Notes

Hey guys, this is a worseman and this is the third part of the first arc in this crossover fanfiction.

Sorry to post this chapter this late due to my busy life that I needed to do.

Anyway, this chapter is honestly a mess that I ever wrote but I don't regret it even though I do regret it.

If you spot any grammar errors or spelling in this story, I will try my best to improve my story.

The Chaldea group, Sougo, and Geiz charged into the largest empty room in the cavern and saw a sight of an uphill slope with a glow at the top.

"What is that thing?" Ritsuka asked, pointing at the uphill.

"An exclusive Magecraft reactor core? Could this be the Holy Grail?" wondered Olga.

"That's impossible. How on earth is this a Holy Grail Cup?" Geiz asked the Chaldea in disbelief as he was looking at the uphill.

"It might be, but right now, we have to stop it. What about destroying it?" Sougo replied with a serious suggestion in seriousness.

"We possibly can, but we're not sure if it has the worst after-effect after being destroyed?" Ritsuka denied Sougo's suggestion of destroying the grail as he worried that the outcome would be fatal due to its size and magical energy.

"Nonetheless, we have to stop it," said Olga with confidence.

"Oh-ho. That is an interesting Servant there."

The group looked up to see a figure standing at the top of the hill. It turned out to be a petite young woman. Her hair was a pale blond, her eyes were a sinister yellow shade, and her skin was also pale. She wore a set of black armor with red, blood-vessel-like markings, her skirt was a black hue and she wore a lower mask plate. Her demeanor gave off something sinister and threatening.

Ritsuka felt a cold sweat from his body after looking at the woman. "Is that Saber?"

"What an incredible amount of prana!" Olga said in shock as she never met anyone with such a presence.

Sougo and Geiz took out their ridewatches in their hands. They turned the dial, revealing their transformation watches, and pressed the top button.

ZI-O!

GEIZ!

Sougo and Geiz slotted their watches to the right sloths and pressed the button on the belt making it tilted. Their belt's screen began to flash. Sougo moved his right arm back while his left hand rose level to his head. Behind him, a see-through clock appeared seemingly from nowhere accompanied by gears that traveled around the clock's edge and the clock hands traveled around anti-clockwise. Geiz threw his both arms forwards, recalled, and spun them around until his left hand clasped the upwards tilt of the Driver and his right clasped the underside. A large see-through, digital clock with red four zeros that act as a timer with smaller digital clocks reading the same time on the side, mirroring Sougo's transformation sequence.

"Henshin!"

Both Sougo and Geiz spun their belt around in three hundred and sixty degrees and it locked in place. On Sougo's side, the clock and gears balanced out and landed on twelves, before the hands split off and pointed to ten and two respectively, with pink katakana appearing on the clock-face. On Geiz's side, the digital clocks spun around right side up; the clocks began to turn red as yellow hiragana lettering appeared behind him.

RIDER TIME!

Silver watch straps appeared and surrounded Sougo, glowed with pink energy while it also did happen to Geiz except it was red and black watch-straps, covered with red energy.

KAMEN RIDER ZI-O

KAMEN RIDER GEIZ

Both Sougo and Geiz turned to Kamen Rider Zi-O and Kamen Rider Geiz as their respective letters stuck to their faceplate.

This caused the Chaldea group to marvel at the transformation of Zi-O and Geiz.

"Amazing!" Both Ritsuka and Mashu said at the same time.

Zi-O and Geiz summoned their weapons and positioned themselves in their battle stance while Zi-O shouted at them, "Everyone, get ready!"

Mashu readied herself putting her shield in front of her body.

"A shield, is it? Be ready to wield it, unknown Servant." Saber stated with an angered and eager expression. "With this sword, I will test if your protection…"

Saber readied her sword in front of herself. "...is true!"

"Mashu! Prepare yourself!" shouted Ritsuka.

"Understood, Master!"

Zi-O, Geiz, and Mashu charged forward as Saber jumped off the hill with her sword ready to swing.


2004

Fuyuki City, Japan

Caster landed in front of the temple before he looked up to see Archer falling and fending off a projectile attack by Ghost, who was now in another form. His parka was replaced with a green parka with a golden yellow trim, a yellow feather on his right side of his hood, and the faceplate was now a shooting arrow and bow downward; Kamen Rider Ghost Robin Damashii. He wielded a gun with a long bird-shaped barrel and two limbs which were on top and below that acted like a bow.

[~~~~~~~~]

Meanwhile outside of the temple, Wizard and Build managed to fend off and defeat the Dragon Tooth Warriors but their numbers were slowly dropped down. As Build dodged the attack, took out his tank fullbottle from his driver and inserted a light blue fullbottle to replace it.

DIAMOND!

Build grabbed the lever and quickly turned it around.

ARE YOU READY!

"Build up!" proclaimed Build.

Build's blue tank armor was replaced with electric blue armor with a shiny diamond across upward and a diamond-shaped armor pad shoulder; Kamen Rider Build RabbitDiamond Form. He quickly lifted his hand and created a projective crystallized diamond-shaped shield and blocked the incoming shot from the warrior's wielding bow. Wizard jumped over the warrior while slashed its back and landed on his feet. He took his ring on his right hand out and placed another ring. He flipped a right switch on his belt.

LUPACHI MAGIC TOUCH GO! LUPACHI MAGIC TOUCH GO!

Wizard hovered his right hand over the center of his belt.

COPY, PLEASE!

Two red magic circles appeared on his left side in the stack and began to move. As the first circle passed through him, the second circle created his duplicate. However, he repeated the process.

COPY, PLEASE!

Wizard had summoned a total of three duplicates and they began to charge and swung their swords at the warriors around them to finish off quickly.

[~~~~~~~~]

As Archer was falling, he deflected Ghost's projectile bullet towards Ghost, who managed to dodge it and nocked it onto the bow. He aimed at Caster below and fired a destructive shot. Caster slammed the tip of his staff into the ground, creating another large spell. Several tree roots formed from the ground and created a large shield around him. The arrow collided with the shield, causing an explosion. Some warriors were annihilated by an explosion near them and Ghost was dragged away while shielding his eyes with his arm where he held his weapon. The shield was, fortunately, able to protect Caster from the destructive force of the attack, leaving a scorched mark on his clothes.

Archer landed in front of Caster on the roof of the temple with a drill sword nocked on his bow. The sword transformed into a thinner spear-like arrow to be fired at Caster. Upon being launched. The recoil shattered the roof along with the arrow transforming into a very large energy shot. However, Caster grinned as if he anticipated the moment Archer fired that specific arrow.

"Here we go! Grand Scale!"

Caster slammed his hand onto the ground and a magic circle with hourglasses and unknown letters formed underneath the three. Archer's arrow had stopped in front of Caster and disintegrated into nothing. Another three magic circles formed and surrounded the battle area. Archer did not know what Caster was planning, but he would not dare fall for it.

Seeing an open opportunity, Ghost moved his weapon to his belt and scanned.

DAI KAIGAN!

GAN GAN MINAA~!

Ghost aimed at Archer and moved his hand to grab as if it was a bow. He then pulled it, materializing a green energized bowstring in his hand. As his weapon was completely charged, he released his grip from the string and pressed the trigger at the same time.

OMEGA STRIKE!

A green energized arrow blasted out of Ghost's weapon and flew towards Archer. Archer noticed the energized arrow coming towards him and quickly jumped into the air from the rooftop to evade. It exploded on the roof upon its impact. Suddenly, his back crashed into an invisible wall in the sky, causing him to fall. He crashed into the center of a crater and he painfully lifted himself when the dust cleared.

"You put Runes in the air!" Archer said loudly as he lifted his head to glare at Caster.

Caster smiled in response. "Yeah, my mentor had a spell that summoned the Gate of the Underworld. I ripped her off. Besides, it won't do us any good to shoot at each other at long range too long. From here, let's go all out and do our usual fight!"

Caster prepared his staff for battle and entered a spearman stance as Archer stood fully up.

"Don't get in my way, Ghost," Caster said without looking behind Ghost.

"Got it!" Ghost replied as he began to aim his weapon at Archer.

"Heh. One's cleverness and tastes are two different things!" Caster announced as he already charged towards Archer and clashed with Archer.


2004

Fuyuki City, Japan

Zi-O flew backward and hit the ground on his back with a thud. He slowly stood up to see Geiz clash with Saber many times until Saber swung her sword to knock him back with full force. She focused on Mashu and charged towards her with her swinging sword. Mashu's shield clashed with Saber's sword, creating a large shockwave that threw up dust and shattered a smaller layer of the ground in pebbles. Sparks flew as Mashu stumbled a bit before she stood her ground for the next sword swing from Saber who looked more willing to crush her. Saber's next swing was stronger than last and sent debris all over the place. With quick thinking, Olga moved forward and took an enchanted stone from her stone. She then threw it into the ground to create a yellow shield of light in front of them to block the flying debris.

Saber swung her two-handed sword relentlessly onto Mashu's shield, each sword-swinging was even and powerful.

"What's wrong? Won't you come forward?" asked Saber as she was about to swing another strong attack until she was hit by an incoming shot. She stumbled back and turned around to see Geiz with a glare as he was pointing his bow at her. Noticing Mashu's top shield coming up towards her face, she dashed back to dodge and continued to attack Mashu while dodging and deflecting Geiz's attack at the same time.

Zi-O took out a dark blue ridewatch with a silver dial design and twisted the dial around, revealing a mixture of silver rhinoceros beetles and a spade-shaped mask with two red eyes. He then pressed the top button, creating a hologram of a mask.

BLADE!

Zi-O began to run towards Saber while slotting Blade Ridewatch on the left and hit the button to tilt his belt. He spun his belt and reached in front of Saber to protect Mashu. A dark blue and light grey armor suit materialized and he punched it; shooting the pieces out and hitting Saber with multiple small hits before attaching himself to him.

ARMOR TIME!

(Electronic Pop mixed with Blade's Opening theme)

TURN UP! BLADE!

Zo-O's feet were light grey armor with dark grey heels, his shins were light grey armor, pale blue knee cap guards, dark blue and light grey thigh-guards, black waist armor pale blue-grey armor and grey sectioned armor on his torso, his arms were covered in grey almost block-like armor, his shoulders had red-backed cards displayed in a fan shape and held by a silver and blue clasp. His helmet was identical to the mask from the ridewatch except a pink katakana word saying 'Blade'. Kamen Rider Zi-O Blade Armor.

Zi-O charged towards Saber and raised his sword. Two blades clashed, creating a spark. Both tried to push their bodies forward by pushing each other back. Unfortunately, each clash had made him lose his balance by her amount of force in her sword. Noticing Zi-O being trembled, Geiz switched his bow to axe and ran towards to assist Zi-O and Mashu. However, he was too late as Zi-O lost his balance by Saber's attack and received a slash across his chest. Mashu ran and tried to attack but Saber made her first move by swinging harder to break her guard. Mashu gritted her teeth as she tried to hold her own against the powerful attack, but unfortunately, Saber then swung from a lower angle and up, sending the shield into the air along with Mashu. Mashu sailed through the air for a bit before landing painfully on the ground with her shield tumbling next to her. Geiz jumped at Saber with his axe striking down at her, but her sword swung and clashed with his axe, sending him flying back in the air.

Ritsuka could not stand still as he realized Mashu and Kamen Riders' lives were in danger. He prepared to charge forward to help Mashu, but Olga raised her hand to stop him.

"If you intend to go help them, you'll only be in the way. No, worse than that."

"But director! Mashu is…"

"Then prepare your resolve."

Mashu looked up from her position and saw Saber closing in with her sword ready to end the fight.

"I understand how you feel. Painfully so… You're her Master. And she is your Servant!" Olga started as Mashu lifted her shield and stood up to continue fighting.

Olga stood with worry but knew she could not do anything to help Mashu in the battle. Ritsuka also felt useless after watching Mashu on the ground along with Zi-O and Geiz. He turned away for a second as his thoughts filled with fear and agony of their death.

"Don't look away!" shouted Olga who continued witnessing the fight, causing Ritsuka to open his eyes and turned to her. "Look straight ahead! Hold your head high! Right now, what should you be doing as Master?"

Zi-O quickly stood up to his feet and summoned two cards that were identical to the part of his shoulder, his hand. They revealed a black lizard with a giant blade that acts as a tail and a deer with its large golden antlers that were shaped like thunder. The two seemingly creatures came out from their cards and went straight through Zi-O's chest to possess. He readied his sword as its blade coated with blue lighting and began to charge towards Saber. Saber reacted faster as she saw him charging at her and blocked his attack with both hands on her handle of her sword. However, his lighting-covered sword caused her to knock back from him.

"Are you alright, Mashu?" Asked Zi-O as he looked back at the beaten-up Mashu.

"I'm alright, Mister Tokiwa, and thank you," Mashu thanked Zi-O, who nodded in reply and readied his sword at Saber. She stood up and lifted her shield once more with a determined face.

Feeling relieved at the sight, Ritsuka was glad that Mashu was being protected by Zi-O while taking in Olga's words in his heart and stood strong for her who supported him. He looked forward with his eyes filled with courage. Geiz joined Mashu and Zi-O and stood beside Zi-O with his readied axe. "I never thought we'd got our ass kicked by a girl who isn't human."

Zi-O chuckled, "Well, she is a servant just like Caster."

"Anyway, is she that powerful because of her class, or was she empowered by something else?" questioned Geiz.

"Saber was probably powered by something that Caster had mentioned before," Mashu answered Geiz with her theory. Her eyes focused on Saber and she pointed, "However, we need to defeat her now."

"Agree," Geiz agreed with Mashu.

"Seems like we don't have any choice to retreat because we have to save this world," said Zi-O as he worried about Mashu's well being and he already decided his first action. He turned to Mashu, "Leave it to us, Mashu. We will handle her ourselves"

Shocked, Mashu was against Zi-O for being asked to rest while letting him and Geiz handle it on their own. She cannot allow herself to be resting in the middle of the desperation battle and needs to assist them whether she was injured or not because this was her duty as a Demi-Servent. She tried to stand up while beginning to retort, "But…"

"If you died here, who was going to protect Ritsuka and Olga if we two are unable to defeat her completely?" Zi-O interrupted, making sense to Mashu while his eyes were focusing on Saber.

Mashu stopped standing with a sudden realization. She should have known better than anyone including her several injuries on her body despite being Demi-Servent. The worst possible scenario in her head played out as she imagined if she and two riders died, both Ritusak and Olga would then be killed off by Saber. Since she had nothing to retort to any further, she sighed and looked away for a moment until returned to Zi-O. "Understood, Mister Tokiwa."

"And please call us our first basic name if we might have a chance to survive," Zi-O told Mashu with a smile under his helmet.

Mashu nodded again but with a small smile in return to Zi-O.

Zi-O began to charge towards Saber with his sword readied while letting his battle cry out. Geiz took a light cyan blue and white ridewatch and turned the dial, revealing the faceplate to be a knight-like helmet with large yellow eyes behind. He pressed the button as it was announced.

BRAVE!

Build thrust his drillcrusher towards the dragon bone warrior to its chest and pierced through it. He pulled his drillcrusher back and slashed across, destroying it. He stepped back from the attack when another one tried to strike him and slashed it before it attacked again. He threw his drillcrusher away to the right and took out a brown fullbottle while taking out his rabbit fullbottle. He shook it and twisted its cap. He inserted it into the left empty slot.

GORILLA!

BEST MATCH!

Build grabbed the lever to twist around while dodging another attack from the warrior.

ARE YOU READY!

"Build Up!"

(Tropical rock music)

KAGAYAKI NO DESTROYER! GORILLAMOND! YEAH!

Build's red rabbit armor was replaced with brown armor with his right hand armed with large reinforced gloves. Kamen Rider Build GorillaMond Form. He swung his glove fist to the right, destroying the warriors into pieces. He summoned his shield and blocked an incoming arrow when he noticed the warrior archers started to shoot their bow. He then punched the shield into shard pieces, sending it towards the bow-wielding warriors for a hit.

Wizard and his duplicates pushed down the thumb to open the black hand palm out of their swords.

COME ON A SLASH, SHAKE HANDS! COME ON A SLASH, SHAKE HANDS!

They hovered his left hands over the black open palm hand to activate their finishing move.

FLAME SLASHING STRIKE! HII HII HII HII HII HII!

They began to charge towards a couple of warriors and cut them down.

[~~~~~~~~]

Caster swung his staff which was lit in flames at Archer who dodged his attacks. From behind him, Ghost fired his shot to hit him but he blocked the shot with one of his swords which were knocked into the air. He dashed past Caster to attack from behind, but his swinging sword was blocked by Caster's staff and kicked to his chest to push him away. Caster, fortunately, dragged his feet to stop himself from flying back and groaned in pain from his kicked chest. He positioned himself to strike but noticed the amount of power that was being given off from the cave. His action also prompted Ghost to look at the energy that was seen as a purple and red pillar.

"What on earth?" Ghost asked in surprise as he sensed a maliciousness from the pillar.

"You've got that right. You've all come this far and you're worried about someone else."

Ghost's eyes glanced up to notice that the white sword that he knocked out of Archer's right hand was spinning through the sky and towards…

"Caster! Look out!" shouted Ghost as he raised his weapon to aim to fire the falling sword.

Fuyuki City, Japan

Saber's sword clashed with Zi-O's sword with a spark of fire and light. Saber swung her sword down to push Zi-O with her full strength but suddenly noticed the point blade flying towards her chest and blocked it with a quick second. She dashed back away from Zi-O and Geiz, who was in his rider armor. It was similar to Ex-Aid Armor except main pink color replaced with cyan blue, black shi and kneecap guards, cyan blue and blue leggings; his cyan blue cartridges with a silver protrusion, his left forearm was armed with cyan blue small shield gauntlet while his right forearm was covered with a black gauntlet, his white and cyan blue knight helmet visor and his yellow hiragana spelled, 'Brave'. Kamen Rider Geiz Brave Armor. His right hand holding a sword which its blade covered in flame and the control pad with light orange and blue buttons that acts as its hilt.

Geiz charged towards Saber with his thrusting sword to her chest, but she dodged his attack and struck him. However, he parried her attack and they began to exchange their attack to each other. He gritted his teeth as he could not handle his sword against her powerful attack despite knowing the basics of swordsmanship. He misstepped his right foot and trembled back, revealing an open area for her to attack and she instantly took the chance. He received a slash in his chest but fell to the ground next to Zi-O.

"Geiz!" Zi-O shouted with concern at Geiz's condition.

"I'm Okay, Sougo," Geiz said while standing up with the assistance of his sword.

"I'm surprised that you two can take a huge beating despite being normal humans, but you won't stand a chance against me, especially my foolish round table," Saber complimented Zi-O and Geiz.

Zi-O widened his eyes with shock at the last few words in Saber's sentence. "Round Table? Wait, are you King Arthur Pendragon of Camelot?!"

"Eh?! Is he a woman in this world?" Geiz asked in shock and turned to look at Saber, 'Arthur'.

"Once before but no more," 'Arthur' answered coldly as she gripped the handle with her two hands and moved her sword backward. She began to charge towards Zi-O and Geiz while her blade coated with a mixture of red, black, and purple energy.

Geiz quickly pressed the light blue button of the hilt of his sword.

KOI CHIN!

Geiz stabbed his sword to the ground, releasing cold air and spreading it around to cover with ice. An ice wall constructed upward in front of him and Zi-O, hoping to stop Saber's incoming attack but unfortunately, Saber's sword smashed it into pieces and sent them flying backward away from her.

"Sougo! Geiz!" Shouted Mashu as she ran towards Zi-O and Geiz.

Groaned, Zi-O tried to fully stand up with his hand palm on the floor but the pain stung him to keep him at bay as well as Geiz. They looked up to Saber who readied her sword and raised it above her head. As Mashu arrived at the almost-defeated riders, she jogged forward and stood behind them with her shield readied in her position.

"Mashu-San?" said Zi-O.

"Don't worry, Sougo. I will protect you and Geiz." Mashu reassured Zi-O and Geiz without looking back.

"I shall answer those eyes." 'Arthur' stated in response to Mashu's defiant eyes as she held her sword in a two-handed grip. "And to the heart, that means to protect its Master!"

An energy surrounding Saber caused the air itself to stir and it traveled to her sword, transforming the blade into the energy of darkness.

"Please endure it Mashu!" shouted Olga with worry, knowing that Saber had activated her Noble Phantasm.

Ritsuka was reluctantly hesitant to go to Mashu and the riders due to both seeing Saber's Noble Phantasm ready to release and simply being afraid of being killed off. However, he gripped his hand into a fist, loathing himself for his fear and so he decided to do something foolishly.

'Screw it!'

Ritsuka ran forward with Fou gripping on his shoulder as he ran towards the battle site.

"Wait, Ritsuka!" Olga shouted but it fell deaf to Ristuka's ear.

"Excalibur Morgan!" shouted 'Arthur' as she swung the sword of darkness towards Mashu which turned into a large beam of darkness. The attack impacted the shield creating a large shockwave that blew apart the wind and caught Ritsuka and Fou off balance. Mashu held her ground as the attack impacted her shield continuously.

Ghost was worn out from the fight against Archer with Caster, but fortunately, Wizard and Build had arrived with the only Build who had changed back to his default form. However, they were placed in a difficult position as Caster was held captive by Archer with his sword at his neck. if they or Caster made a sudden movement, this could result in the death of Caster.

"It looks like this is the end," Archer stated while Ghost tried to think of a way to help Caster.

"Will that shield resist the sword? Or will that sword pierce the shield?" Asked Caster.

"A long time ago, I heard something similar to that," Archer responded impatiently.

"Oh? And what was the answer?" asked Caster.

"The answer was a 'paradox.' Only a contradiction was produced," Archer responded.

'Are they referring to Mashu and Saber?' Ghost thought as he gave a glance to the area where the purple light was still bright.

"Hah. I don't know about that. I always think the same thing about the story. If both things are equal, then isn't it all down to the skill of those who use them?" Caster wondered aloud. "Or let me put it another way. If you're losing because of the weapon's performance, then it's humans that compensate with wisdom, yes?"

Caster lifted his hand and flicked a stone in front of Archer's face. Suddenly, the stone flashed with light before exploding, blinding Archer, forcing him back, but he stabbed his sword into Caster's back, much to the horror of the Riders.

"Caster!" Ghost shouted in horror.

"Ghost, Wizard. Get ready!" Build shouted much to their surprise and grabbed his lever to turn.

Archer smirked but he gave a confused look as he couldn't move his swords and hands. The reason was that roots were growing out of Caster's back which wrapped around his hands. Caster's seemingly corpse turned into the wood before he moved his flesh and body out of a line splitting the statue although he gave up his upper fur coat and shirt.

"Don't underestimate a Sage of the Forest!" shouted Caster as he fully jumped out of the way and Archer was forced to discard his current swords as the statue flashed into light, before exploding in a cloud of ash.

"Now!" shouted Build as Ghost and Wizard ran through the cloud and both slammed and kicked into Archer's stomach.

Build finished turning the belt's lever and ran forward. As He hops up, he smashes down to the underground, and a white energy chart flying up to the surface with the dotted line securing Archer in his place. He launched back up to the top of that chart while announcing loudly, "The laws of victory have been set!"

READY GO!

VOLTECH FINISH! YAY!

Build launched up and pointed his left leg as he dived towards Archer locked into the chart. The treads on his left leg grind into Archer's chest and explode, sending him into the ground with pavement bricks smashed and dust erupting into the air. When the dust cleared, Archer slowly stood up despite feeling the effect of surging energy throughout his whole body.

"Sorry. This is all new to this!" Caster said as he landed on the roof of the temple. He pointed his staff at Archer as a red flash before a circle of fire surrounded him. A large wooden hand erupted upward and grabbed Archer and crushed him in its grip before slamming him down into the ground.

"Is it over?" Wizard mumbled, waiting for the outcome.

Caster dismissed the hand and Archer was seen on the ground unconscious with heavy wounds on his body. Archer slowly disappeared into light and particles to the earlier Servants.

"Caster! You're all right!" shouted Ghost as he jogged towards Caster who jumped down from the roof.

"Sorry about the scare," Caster apologized to Ghost.

"So, that's your plan involving Sento including us to trick Archer into your trap?" questioned Wizard.

"Of course, even though he knew my plan with a glance," Caster answered, pointing to Build.

"Well, we can't blame you for this situation," Build said. "Besides, where did you get that stone? It helped us out otherwise we would have been stuck there all night."

Caster tossed the stone he still had and caught it. "True. It's just better than nothing. Now then, let's go assist our friends back there."


2004

Fuyuki City, Japan

Mashu's shield was held strong against 'Arthur's' Noble Phantasm's beam. Ritsuka, Olga, and Fou stood there and just watched the scene. They were helpless to assist Mashu in battle including the injured Zi-O and Geiz who tried to stand up. Mashu gritted her teeth in agony by a powerful force from the beam. She does not know if she could stand her ground over time and hoped for Saber's Noble Phantasm to be run out. However, she fell to her knees on the ground out of sudden as her strength slowly dimmed.

"Mashu!" Zi-O shouted as he tried to get up fast despite the pain slowing him down along with Geiz.

Mashu tried to stand up but her vision became blurry and she felt dizziness in her head. She had lost her focus in front and her eyes became heavy and closed as she could barely hold against the beam.

'I'm sorry, everyone. I failed,' Mashu thought in regret as she was about to fall into a slumber.

Suddenly, a hand was placed on top of Mashu's hand while the other touched her back. She instantly opened her eyes to turn around to see that it was Ristuka. He held her hand tightly to her shield not to fall while his eyes looking forward, filled with courage. She was shocked to see him here and wanted to tell him to get away but she could not as she was happy that he was there to help her.

"Sempai..."

Ritsuka's eyes looked to the right where Mashu was and his mouth turned into a smile. "I believe in you."

A Command Seal began to glow brightly where Ritsuka's left hand was with Mashu's shield and a white aura covered her entire body and began to glow as well. She felt her strength regained before disappeared and her body became lighter. As the white aura dispelled, She became determined and stood up with the assistance of Ritsuka to protect him, Zi-O, and Geiz

"Please watch me, Master, and the Riders."

Mashu's shield began to glow with power and light than a massive circular shield made of light formed from it. The shield of light expanded until its diameter nearly reached around the length of a semi-trailer truck. Saber's Noble Phantasm's Beam was unable to be overcome by the power of the shield Noble Phantasm, protecting her, Ritsuka, and the Riders from its destructive beam.

"The Noble Phantasm…" Olga stared in awe at the manifestation of Mashu's shield Noble Phantasm.

Zi-O and Geiz successfully stood up to their feet and they were captivated with amazement by Mashu's Noble Phantasm.

"Wow," Geiz mumbled with surprise while Zi-O stood quietly without saying the word.

Mashu's Noble Phantasm transformed into a hard light stone wall akin to castle walls that were around the size of the circular shield. Mashu roared out as the beam impacting the wall was deflected and sent back at 'Arthur's'. Upon seeing the wall, 'Arthur' realized to her shock what made the shield so familiar to her.

"That shield is…"

'Arthur's' was hit by her Noble Phantasm attack, blasting the ground she was standing on to dust creating a large debris cloud. When the dust cleared, Saber was seen standing, but she appeared to be injured from the blowback of her attack. Frustrated and angry by her attack being deflected so easily, 'Arthur' gritted her teeth.

"We did it, Mashu," Ritsuka sighed in relief and turned to Mashu but only found her to be exhausted after utilizing her Noble Phantasm.

Mashu tried to stand straight, but her regained strength was fading fast, possibly due to activating her Noble Phantasm for the first time. She slouched forward and Ristuka had to catch her while supporting her grip on her shield. The wall started to deteriorate to the response of her weakened state. "Mashu!"

Zi-O and Geiz saw 'Arthur' who was looked ready to kill them once and for all as her energy flared and she lifted her sword above her head. "Excalibur…"

"We need to finish her now before it's too late!" Zi-O shouted as he pressed the button of both ridewatches on each side of his belt.

"Got it" Geiz agreed as he does the same as Zi-O.

FINISH TIME!

BLADE!

BRAVE!

Both Zi-O and Geiz pressed the button in the middle of their belt to make themselves tilt and spun it around in three hundred sixty -O summoned three cards in his hand which one of them was deer but the other two were new; one was a locust whose font was black and had wings while its back was green and had a huge leg and the last was the golden jaguar with a rocket booster. Three seemingly creatures came out of the card and possessed through Zi-O's chest. He stabbed his sword into the ground and a red and blue sparkling along with his suit until it gathered in his foot. Geiz grabbed the hilt with both hands, positioning himself towards 'Arthur'. Zi-O ran forward with his speed due to one of the cards' abilities.

CRITICAL TIME BURST!

Geiz swung his sword down, manifesting a flame projectile slash and firing it towards 'Arthur'. 'Arthur' stopped her noble phantasm when she saw the projectile slash flying towards her and blocked it in time but she was unable to endure it due to her injury. The projectile slash exploded in flame in front of Saber, making her stumble back. Zi-O jumped up to the air and forwarding his left leg out, which was coated with lighting, for the finishing move.

LIGHTNING TIME BREAK!

Zi-O's foot landed on 'Arthur's' chest upon impact, sending her to fall to the ground. Zi-O landed on his feet safely and looked at her in her defeated state, but despite her furthermore injury, she would not dare not to lay down to surrender. She glared at the riders and the chaldea with fury and she would still want to kill them no matter what. The Chaldea and rider groups stood at the ready for one final clash. But then a chant was heard throughout the cave.

"My Magecraft is a Cage of Flames. A flaming yet verdant giant. Retribution. A shrine that purifies the evil of human affairs."

Caster rushed forward out of nowhere from behind, passing the pair of Ritsuka and Mashu along with the arrival of Build, Ghost, and Wizard who also stood behind them.

"I'm proud you've held out this long." Caster commended as he jumped through the wall and landed in front of 'Arthur' who was going to use her Noble Phantasm. "The one who destroys… WICKER MAN!"

Caster spun his staff and the top of it flashed red similar to his finishing act against Archer. Under 'Arthur', a magic circle formed before a giant humanoid statue made of wood with a cage-like torso came out. Due to its summoning being under her, 'Arthur' was now standing on the wood statue's head. She quickly jumped off as the wooden giant raised its hand to grab her only for it to miss as she agilely ran on the arm before preparing to chop its head, but it quickly grabbed her in its other hand, preventing her from moving her limbs to attack. It opened the gate on its torso before throwing her into the cage. After closing the gate, it fell forward onto a bed of flames that quickly engulfed it and the victim inside. Everyone present felt a vacuum of air as the flames grew strong before the now flaming giant burst into a pillar of fire that went through the ceiling of the room and into the cloud.

When the fire ceded, the ash and smoke cleared, 'Arthur' stood silently tall despite the damage she incurred from the attack. She stared at Ritsuka and Mashu as they stood on the opposite ends of the shield. Ritsuka stood on the right side while Mashu stood on the left.

"Victory for the power that protects? I see… Such as that innocent one…" 'Arthur' smiled peacefully to the surprise of the group, a reverse of her threatening demeanor earlier. "Ultimately, no matter how fate changes, I face the same end when I'm alone."

'Arthur's' body slowly disappeared into a golden light different from the Servants that the group defeated earlier.

"What does that mean? Do you know something?" Caster asked as he wanted to know why 'Arthur' restarted the Holy Grail War.

"Eventually, you will come to know, Ireland's Child of light. The Grand Order…" 'Arthur' denied Caster's question except for her short answer which surprised Olga. "And the battle over the Holy Grail has just begun…"

'Arthur' gave her glance at Ritsuka to Zi-O and Geiz and chuckled. "You two are the fine but persistent warriors to continue to fight the impossible. And you, Master, if you require my service, look no further than the summoning system."

"Did she praise us two?" Zi-O asked Geiz.

"I think so unless her word is a taunt to us," replied Geiz uncertainty.

"Hey, wait! What do you mean by…" Caster asked but felt that he was also disappearing into the light. He turned around to face Ritsuka and Mashu. "Kid, young lady, I'm leaving the rest up to you!"

"Caster!" shouted Ritsuka.

"If there is a next time, summon me as a Lancer!" shouted Caster as he rested his staff on his shoulder. He made a smile before he and Saber disappeared which the group could only silently sadden for the sane servant who helped them through the conflict of Fuyuki.

"Confirmed. Saber and Caster are both gone. Did we… win?" Mashu wondered.

"Look like it," replied Zi-O who took Blade Ridewatch off his belt to return back to his default form and Geiz did a similar action with Brave Ridewatch.

A beep sound from Ritsuka's communication bracelet snapped Ritsuka and Mashu out of the blue. He pressed the button to switch on and heard Roman's congratulating voice. "Well done, Mashu and Fujimaru! It looks like I can't get any visuals from there so I can't see your happy faces."

This made Ritsuka, Mashu, and the riders smile.

"Director, now we don't have to worry about Singularity F…"

However, Olga was in her full thoughts of worries, ignoring Roman's voice while Fou looked at her with both curiosity and worry. "Grand Order… How did the Servant know that name?"

Ritsuka, Mashu, and the riders walked towards Olga and Fou, who was the only one who turned its head around to them.

"Director?" Ritsuka called Olga.

Olga snapped out of her thoughts when she turned to the group who looked worried when she did not respond earlier. She gave a small smile to hide her worries and congratulated the two. "Oh… Well done, Mashu and Fujimaru."

Fou decided to jump onto Ritsuka's shoulder before the director continued her congratulations. "Mashu. Even if you're inexperienced, or even if you're a temporary Servent… You still made a wish and the shield opened to you."

Mashu nodded in response.

"Even if you do acquire the True Name, you didn't have the slightest interest in becoming that Heroic Spirit. I'm sure that's why the Noble Phantasm responded to you." Olga turned away with a sigh before gesturing to hand out that a miracle in Mashu's time in need. "That's some fairy tale."

"Eh?" Zi-O said for Ritsuka and Mashu.

"I'm just teasing you. Never mind me." Olga gave a tired glance towards Ritsuka and Mashu. "Nonetheless, it's inconvenient using a noble phantasm without a True Name, I'll think up a good speed for you. Let's see…"

"What about 'Wall of Humanity' because her shield protects anyone?" Zi-O suggested the name to Olga for the name to Mashu's Noble Phantasm.

"Hey! I'm thinking! And no, your suggestion is stupid," Olga scolded and denied Zi-O with narrow eyes.

Zi-O felt dejected by his denied suggestion from Olga's harsh words. He does not know every alias he came up with was rejected many times. Geiz patted his shoulder and said with little sympathy, "Sorry, but the director is right. Truth to be told, your naming admittedly sucks."

"That's not comfort, Geiz," Zi-O replied, looking at Geiz with little disappointment.

"Ah… What about Lord Chaldeas?" suggested Olga with a smile. "The name Chaldea has a meaning for you too, doesn't it?"

"Yes! Thank you, Director," Mashu gave a smile and a short bow to Olga. She turned to her shield, now dubbed: Lord Chaldea. "Lord Chaldeas…"

Ritsuka gave the name some thought before nodding in agreement. "That's a pretty fitting name, Director."

Olga gave her smile in return to Ritsuka who complimented her smile too.

"Well, I guess it ends well, I suppose," said Zi-O.

Suddenly the sound of the clapping was heard, catching the group's attention with shock and worry on their faces. The group stared up to see a silhouette standing at the top of the hill. They gave a serious and cautious expression at whoever was clapping on the hilltop. A voice began to speak as the Chaldea group heard the familiar voice that they recognized. "My, I never thought you would all get this far. This is an unforeseen element that goes beyond what my tolerance allows."

"You're…" Ristuka's eyes widened in surprise at who was standing far in front of the group. The silhouette revealed to be a man in his forties. His dark auburn hair was shaggy and long that reached over his shoulder and his eyes remained close as it did not reveal his color eye's iris. His outfit was a dark green coat with both a black tie and a white shirt.

Mashu looked hopeful as she looked up to the man. "Professor Lev?"

"Professor Lev, you say?" Roman asked over the communication bracelet device.

"That's impossible. How the hell did he survive? We didn't find his body," Kota said dumbfounded.

"A friend of yours?" Zi-O asked as he turned to Mashu.

"Yes. I'm glad he's fine." Mashu replied.

"Something isn't right," Wizard muttered as his sense was tingling violently coming from Lev. "And I don't like it."

Wizard was not the only one who found it odd as Build and Geiz also noticed something wrong with Lev.

Olga was stunned as she stared at the familiar form of the Professor who stood at the top of the hill with a dark expression. Her eyes watered with tears of happiness as he ran forward to meet him. "Lev… Lev!"

As Olga ran with a happy expression, there was something ominous about Lev. "Lev! Thank goodness, you're alive! Without you, I don't know what I'd…"

"Hi, Olga. It seems you've had a rough time, too," Lev said with a calm tone and smile.

"Yes, that's exactly right, Lev!" shouted Olga with her present smile. "With all the unexpected events, I thought I would go crazy!"

As the group watched the exchange, Ghost noticed a dark aura surrounding Lev as if he was not human and Olga was running towards him which helped him to conclude with a terrible feeling. He began to run off the group while shouted, "Director?! Get back, he isn't human!"

Ghost tried to reach Olga but only to be hit by an invisible wall with a purple light that shocked him a bit.

"Ghost!" shouted Zi-O as he ran to the electrocuted Ghost along with Geiz who however just ran past them while summoning his weapon.

"The director… She's in danger!" Ghost replied with worries as he stood out with a little help.

"What?!" Zi-O shouted aloud as he turned to Olga with worry.

Geiz slotted his transformation ridewatch to his bow and aimed at Lev. Geiz pulled the trigger backward, creating yellow projection energy, and fired.

FINISH TIME:

GEIZ

GIWA GIWA SHOOT!

A yellow projection arrow flew up to the air towards Lev but only exploded upon impact on the barrier. Geiz clicked his tongue in irritation, "Damn it!"

[~~~~~~~~]

Olga stopped at his feet and turned around to see a cloud of smoke slowly disappearing in the air with surprise. She looked down to find Geiz aiming his weapon, Zi-O helping Ghost to stand up and the group ran towards them with haste. She was clueless at the scene and their action until Lev spoke out, "It seems that they somehow found out about my true intention."

Olga turned back to Lev and asked, "What do you mean, Lev?"

"I'm so furious with all these unexpected events," Lev sighed in fury, ignoring Olga's question. "Romani, I told you to come to the control room right away."

"Lev?" Roman wondered to his surprise.

And you, Olga…" Lev said to Olga, wh looked up with wonder and a hint of fear in her eyes due to seeing him vexed as he continued, "I planted the bomb under your feet. I can't believe that you're still alive."


Extra Notes

I do not know what Blade Armor can do but I guessed that it can summon the rouse card and does the same action as the riders in the KR Blade Series. As for Brave Armor, I think it's similar to Kamen Rider Brave's power and abilities in the KR Ex-aid Series.

I made little changes to the scene to make this story a little different from their mobile game, manga, and anime versions. However, it will retain the original storyline.

I'm not sure if this fight scene that I wrote is good to catch your interest. I technically tried to write the rider to be a little weak against the servant as most of the riders are human (Except a few are not human anymore) while the servants are heroic spirits that can easily kill a person whether they are a mage, magus, or not. However, I made the riders be on the half level of the Servant but some of their multiple forms can somehow defeat them including some of their final forms.

If you all have a problem with it along with my story, I will try my best to rewrite it to suit your taste.
