Shirou POV

Shirou could only wonder how an outsider could enter Kagetsu-sou. This place was fully booked by the IS academy, especially at night when everyone was asleep.
"What are you doing here?" the woman asked in a surprised tone.
"That's my line."
"This-this-umm?" The woman acted like a child who was caught doing mischief.
"Well, whatever, I will catch you first and think about what to do. After that, I'll think about it after morning comes."
"Just try it if you can!" The woman jumped onto the roof and ran outside.
"hah..." He was quite surprised that the woman had amazing physical abilities but was not comparable to the enforcers from the clock tower or the holy church; with that, he started chasing from behind.

Tabane POv

The man, just because he could imitate her creation, thought he could catch her as if only Chican could match me.
She looked behind her to see if the man was chasing.
"I know that he has poor physical abilities."
"Who?"
"Of course it's..." Since when was he here, she couldn't feel his presence.
Tabane had to admit that this man had the same physical abilities or more than her.
"Give up?"
"Don't joke with me."
Tabane wanted to take out a weapon from her storage, but she felt a heavy blow on his stomach.
"uh..."
She could only see the cold gaze directed at her before she fainted.
end POV

Shirou looked at the woman and took her towards the inn. While on the way to the inn he thought about what he should do with her, he decided to put her near the teacher's room.

in the morning

Chifuyu POV

crip, crip

She heard the sound of birds and started to wake up.
"ark..."
Her head hurt from drinking too much. She realized after chatting with her brother she drank beer to relive her frustration because of the existential crisis she was experiencing, because she couldn't tell the truth about the secret of their birth, the truth that she herself wanted to know the secret that Shirou had, but she was very afraid to reveal the truth, but she still has secrets she wants to keep for her brother's good.
She started to get up from his futon and went outside. Outside, she saw Tabane, who was sleeping outside.
"huh!?"
She was confused about why Tabane was here; she knew that she could come here at any time, but she didn't expect that she was unconscious in front of her room.
"Tabane, Tabane, wake up!"
end POV

Chifuyu tries to wake up Tabane, who is unconscious.
"Uk-urk...Chican" Tabane started to wake up from her fainting state.
"What are you doing in front of my room?"
"uh-huh"
Tabane was confused; she remembered that she wanted to put a surprise after that...
Memories of last night's events began to emerge again.
"Where is that man!?"
"Man?, you mean EMIYA, he's in his room."
"But last night..."
Tabane Tabana started to explain what happened last night to Chifuyu. Chifuyu was silent when she heard Tabane's story; she knew from Ichika's story that EMIYA had the body of a fighter.
"That's enough; it's too early to have a headache; just go look for your sister."
Chifuyu suggested to Tabane that she didn't want to add to her headache because of the mess her best friend usually made, but she was impressed enough that EMIYA was able to stop Tabane.
"Haaaiiii!" Tabane replied in a childish tone.

(The story continues without any surprises from Tabane; Cecilia never meets the inventor of IS, and Ichika remains uncertain about what he should do with his life.)

IS private users and SAM users are gathering; there are Ichika, Lin, Cecilia, Laura, Charlotte, Shirou, and Houki.
From a distance, they saw Orimura sensei and a woman coming towards them.
"Everone this Tabane Shinonono." Orimura sensei introduces the woman with red-purple eyes and long, dark purple-pink hair that extends to her hips with some loose bangs, which cover her forehead. She wears a frilly maid-like blue and white dress, ribboned tights on her legs, a pair of robotic rabbit ears, a lab coat, and Mary Jane shoes (similar to those in Alice in Wonderland), revealing a great deal of her cleavage. She also wears a gray bracelet on her wrists.
"""E-eehhhhhhhh!""" They were all shocked except from Ichika, Houki, and Shirou.
"Ah! That's you, a man who doesn't hesitate to hit a woman,Tabane pointed at Shirou.
"Why should I hesitate to hit an intruder, let alone someone with physical abilities beyond that of an ordinary human? What's more, your clothes are also semi-IS; even if you are hit by a missile, you will survive, he stated from the results of observations and a little help with the magecraft he did last night.
"SHUT UP! I don't want to hear that from someone who is even stronger than me; in fact, I doubt that SAM is a machine, let alone with more energy than any generation, even for the fourth generation that I just built."
"Heeh~, what is a wounded ego I heard? Besides, IS itself has a fatal weakness because too much automation connected to the user's mind makes their natural mental defenses weaken so they are easily hypnotized." "Don't you all believe it? OK, let's take a look at everyone here: Charloote; she has high compatibility with the core of IS after she lost her mother and was not accepted by her father's family; Laura, a test tube baby who was born only to be a soldier even since childhood; Cechilia, a girl from a noble family who knows the secret of their parents' deaths but is afraid of losing the glamorous life they have; then Lingyin and Houki are two girls who are obsessed with their childhood love, which even the person they like isn't aware of; the last one is Ichika and Chifuyu, who weren't even"
"That is enough!" Chifuyu shouted; she looked desperate with a lot of cold sweat visible on her face.
"Well, it looks like I'm revealing too many of your secrets, but back to my topic about IS weaknesses, even though the weaknesses I mean are more towards their users, and that raises questions."
They couldn't say a word; part of them felt angry and also afraid because their darkest secret was being revealed in front of people they could consider friends. At the same time, they were also curious whether the inventor of IS knew about this.
"Do you know about this weakness? And why do you let this problem go, or do you know but let it go? Unless you do it on purpose and you have the tools to manipulate someone's mind."
They fell silent and looked at the IS inventor, who gave a cold look at Shirou, who continued to reason. They could only be surprised, especially those who had known Tabane for a long time because this was the first time they had seen her angry.
"Well, just talking won't prove it, right? Then how about we do a demonstration? I'll hypnotize one of you." Shirou finished his words while observing them until his gaze stopped at Houki.
"EMIYA STOP IT! We are here to do flight practice," Chifuyu shouted, reminding them why they were there.
"OK, OK, I understand; besides, sometimes hypnosis can also be destroyed by itself, even though it takes a long time," before he continued his words and pointed toward Houki, "after all, the only person who will suffer is herself."
"Can I continue with the schedule for today?" Chifuyu looked toward Shirou, who responded with a nod.
"You must be wondering why Houki is here." Chifuyu asked a question and was answered with nods from the girls.
"Because from now on Houki will be a private pilot, and Tabane here will provide the IS."
"Thank you, Chichan, and go die, you meddlesome person!" Tabane answered with a cheerful voice and ended with a hateful tone that she directed at Shirou.
"Now this is what you have been waiting for, especially for you, Houkichan."
With a signal from Tabane, an object descended from the sky and arrived in front of them and turned into a red IS.
"This is Akatsubaki, the fourth generation IS that I created. This is the most advanced IS because it has everything that the previous generation had; isn't it amazing?"
"""uahhh...""" The teenagers there were impressed with the IS in front of them.
Tabane felt very satisfied; she felt better because her creations were admired by teenagers after the man almost revealed all her secrets.
"Come on, Houkichan, we have to adapt it to your body."
Hearing that, Houki approached her sister and started using the IS, while Tabane started to adjust the system.
"Aniki, I want to ask something, Ichika said, approaching Shirou.
"Kid, listen, whatever secrets Chifuyu is hiding, she's doing it for you; after all, a person's life begins with the bonds they form; therefore, cherish and protect those bonds."
"Thank you," Shirou nodded. He heard the arguments made by the girls.
"This is not fair; just because they are siblings, she can get private IS."
Lin said in an envious tone that she felt threatened because there would be more competition for Ichika. To which the girls responded with a nod.
"Hey, hey, why are you jealous? Don't you also have a private IS too? After all, it's not like you guys have expressed your feelings to hump!" The girls covered Shirou's mouth with their hands forcibly so that he wouldn't reveal their feelings to Ichika, who was behind him.
"Emiya San, can you shut up?" Cechilia said.
"We still haven't forgiven you." Charlotte added
Lin and Laura nodded in agreement.
"Puah...OK, OK, I understand." Shirou obeyed them, and Ichika just stared curiously at what was going on. Before Ichika could ask what happened, the sound of IS flying into the sky was heard.

fooosh

They saw from below Houki moving quickly using her IS and firing energy shots from her katana, then destroying all the missiles sent by Tabane.

"ORIMURASENSEI They looked at Yamadasensei, who came in a hurry.
"We have an emergency situation! Please see," she said as she handed a device.
"A rank mission, start looking for a solution to solve this. STOP testing!"
"There's something you have to do," Orimura sensei gives an order.
"Eh who is she?" Yamada sensei just realized Tabane's existence.
"She is Tabane Shinonono"
"EH!"

in Windswept Flower Hall

all the private IS owners, SAM users and teachers gathered. The dimmed lights draw attention to the large holographic display.
"Two hours ago, the third generation of IS Silver Gospel, a joint development between the US and Israel, lost control during testing in Hawaii; we have received news that it is now leaving the test area." "Satellite tracking shows that the Silver Gospel's path will pass through local airspace at a point two kilometers from here in about fifty minutes. The Academy's orders have ordered us to respond"
"Academic personnel will use IS training to cover air and sea routes. Responsibility for the main goal will be handed over to those who have personal IS and that includes you as well Emiya"
"Now we will answer questions about missions. Raise your hand if you want to speak"
Shirou felt funny about this incident, after the younger sisther of the inventor of IS got a private unit, there was a military unit that went out of control, what's more, this unit had specifications that exceeded third generation units, so the most appropriate choice was to send Ichika, who has IS abilities that destroy energy shields, and Houki who has a new generation of IS,especially because Tabane is here, she will make sure her sister shines on the stage she has prepared.
"WAIT!"
Speak of the devil heer she comes trespassing into the room and started suggesting Houki as Ichika's companion in carrying out the mission.
"Excuse me!" Shirou drew all their attention towards him.
"Chifuyu sensei are you sure you only sent the two of them, I just want to remind you that what they are facing is a military unit that will be used on the battlefield, in other words Silver Gospel will not stop until all its enemies are killed" his words got everyone's full attention, especially Ichika and Houki about how risky this mission was.
"That's why Emiya I said we only have one chance, unless you want to help them?" Orimura sensei replay
"As much as I'd like to help I think it's impossible especially as SAM doesn't have an IS network communications system"
"why not?"
"because SAM is not IS, IS itself is connected to one another which forms a unity because of this unity IS can be tracked using satellites, whereas for SAM there is only one unit for one individual and it is quite difficult to track SAM using satellites, how do you think I can use SAM for a long time without anyone realizing it"
"in other words, SAM cannot be used for long distance communications"
"yup" "in other words we will carry out Tabane's plan"

(The incident will be the same as the anime until Ichika faints from protecting Houki)

"Huh, as I thought"
Shirou started walking towards his and Ichika's room.

sreeek

Shirou closed the door and stood behind Houki
"Have you woken up from your fantasy Houki Shinonono" "How does it feel to almost lose the person you love because of your pride"
"shu-"
"I didn't hear you"
"SHUT UP!" "I know this is all my fault, I just don't want to be left alone, I'm not someone like you Emiya san who can create something equal to IS" "I'm always in Tabane's shadow, which is very annoying"
"I don't know, I'm here to give a cruel sentence, 'no one cares' no one cares about other people's suffering except those who have experienced the disaster themselves"
"?!" Houki looked at Shirou and found no one there, only herself and Ichika in the room.

With Shirou

After Shirou finished giving a few words to Houki and left her in his room
Shirou wanted to give the communication device he made during the mission to Chifuyu or Maya but they forbade him from entering the room and told him to be on he thought about leaving it in a box in front of the observation room and giving a message about what it was and an apology because he was about to do something stupid. That's why he was here, on a quiet beach with no one around.
"It seems like I've never changed either"

"Trace On"

with that, ARCHER's black bow and the hero Beowulf's black sword appeared in his hands he himself didn't know where the Silver Gospel was but with Hrunting it wasn't a problem all he needed to know was the target, the rest would be left to this sword. He started doing archery poses, putting Hrunthing on the bow and alter it to make it more arodynamic.

"HRUNTING"

With its real name called, the sword shot towards the target wherever it was.

"Then now, Arcurrend limited off"
His armor appears with the addition of a black shoulder cape and The design and visor both appear to blaze blue flame. The helmet developed horns on its sides, the gauntlet sharpened like a beast claw, and tendrils emerged from the rear of the armor, His armor became visible like a vengeful spirit. He quickly caught up with Hrunting.

in command room
Chifuyu is very worried about her brother but she still has responsibilities that she must fulfill.
"Orimura sensei, we have a problem Emiya san, he went to fight Silver Gospel alone" Maya said in a panicked tone and handed over a box containing a communication device and a letter that Shirou had left behind.
"What?! That's fool what he's thinking?!"
"Orimuar sensei We got a satellite image of the location of the Silver Gospel, there was an attack on it" an operator shows the picture he got, it shows the Silver Gospel being hit by a red light and forcing it into combat mode then it is shown again an unknown black unit starting to fight with it.
Chifuyu immediately used the communication device that Shirou had made over her ears.
"Emiya, Emiya are you hear"
"..." "Chifuyu sensei?"
"What are you doing!"
"Just hunting some bird, Don't worry too much, I'm out"
"Emiya, Emiya, Emiya "
tut tut tut

With Shirou

Shirou followed the direction Hrunting was walking in. He could see Silver Gospesl who was taking cover in an energy dome. Hrunting penetrated the dome without any difficulty at all and before it hit the pilot Shirou dispersed it. Shirou started attacking Silver Gospel, leaving behind blue flames every time he moved, he was still not very used to air combat.
In the battle he heard a voice calling from a communication device.
"Emiya, Emiya are you hear"
Shirou couldn't answer because of the onslaught of laser beams he received from the Silver Gospel which he responded with a shot of blue fire energy from his arm, he approached quickly and delivered a blow to the Silver Gospel to get away from him.
"Chifuyu sensei?"
"What are you doing!"
"Just hunting some bird, Don't worry too much, I'm out"
with that last message he immediately destroyed the communication device he had embedded in his helmet.
"I know that, fighting and talking at the same time is a disaster"

pshhhhh

Shirou managed to avoid the laser attack that almost hit him. Shirou focused his attention on the Silver Gospel and started moving towards it then started shooting blue flames at it when it got close he summoned the Centurion and gave it continuous slashes towards the arms, ribs, thighs and head before he tied its legs with a whip that came from its back and threw it into the sea.

blaaarrrr

Silver Gospel came out of the sea and it form changed because of the second shift he started to have wings of light and made a voice like an angel.
"really an angel? If the magus family who uses the Kabalah found out about this, what would their reaction be?"
Shirou threw the Centurion into the air and hit it with his punch, and it shot out destroying the Silver Gospel's shifting energy shield

prank crass

Shirou summoned Arcurrend's stand-by mode and changed it into sword form and started attacking again using it, which made Silver Gospel only dodge before running away and shooting energy beams in all directions Shirou dodged and blocked easily.

prank

Silver Gospel was hit by a gunshot, Shirou saw the line of fire coming from there, he saw Laura using her railgun and behind her were Cechilia, Lin, Charlotte, Houki ,and Ichika with a new IS form because of his second shift.

"""Emiya san/ Aniki""" they called Shirou and headed towards him.
"ho, you did a second shift kid?" Shirou ask question toward Ichika
"yes"
"Then I'll leave the rest to you"
"""YES SIR""" with that Shirou returned to the inn.
(the story continues as in the anime until Silver Gospel's defeat)

in the inn

"Good job everyone, that's what I would say if you didn't make a big mistake, especially you Emiya" Chifuyu said
Shirou wanted to argue but was cut off by Chifuyu
"Once you return I want you to make a confession report and for you Emiya I want a detailed report about this incident and the reason why you destroyed your communication device."Chifuyu ordered which Shirou responded with cold sweat, he really hated making reports after fighting.
"but it's good that you're safe. After you rest, you'll get intensive training from me, now disband" With that Chifuyu walked away and was followed by Maya
"urk" Those who remained looked at Shirou who was holding his stomach.
"Aniki, are you hurt?" Ichika asked Shirou worriedly
"no I'm not hurt, I just have the trauma of making a detailed report"
"to think that a so-called god of war would be traumatized by making a report" Laura said
"God of war are you kidding who gave that stupid name, after all I'm still human, if they find a god they themselves will be more afraid"
"Aniki, don't you know what you're called after the tournament?"
"How do I know I'm always in the cabin after class"
"What do you mean they will be afraid if they see the god Emiya san?" Charlotte ask
"Charlotte please don't talk about this again and don't ever call me the god of war you all understand"
"umm" Hearing Cahrlotte's reply Shirou started to go towards his room to rest, followed by Ichika and the girls.

in the cliff

Chifuyu is seen chatting with Tabane about the events involving Ichika and entering the IS academy, and the stage that Tabne prepared for Houki and how genius Tabne is to be able to do all that herself.
"No Chican, there is one thing that is not included in my plans"Tabane said while looking at the moon
"Emiya huh?"
"um,Shirou is also a genius Chican, he was able to make a SAM without me knowing and use it in battle without being caught by the government for a long time."
"Shirou? I never knew that you could call someone without adding a suffix, let alone say their first name correctly"
"Maybe I'm in love?"
"Huh?" Chifuyu turned towards Tabane and found no one there.
