The moon's light proudly shone downwards the forest that housed the spider demons. Demon Slayers were brutally massacred from their own hands and their teammates' hands.

Giyu Tomioka stood still with some dead Demon Slayers in the area while the only ones who were saved were still audibly alive.

"Were you acquainted with any of them?" Shinobu asked. "There's only a few here that survived miraculously."

Giyu ignored her question and continued to look at the few dead bodies.

"We were advised that several rookie Mizunoto had joined the battle, but they might be dead now, don't you think?"

"Let's go" Giyu said in a dull tone, completely debunking what she said.

Soon, the two Hashiras took off in a sprint in search for the Mizunotos they seek to provide support. Giyu, in his head, had a feeling that whoever the Mizunotos are were the ones responsible for saving few skins this night, and they might not be dead to what Shinobu claimed them to be.

"Isn't the Moon lovely?"

Shinobu asked to her partner. It wasn't a question, to be exact. In fact, there was a hidden message behind it that indicated Shinobu's feelings towards the Water Hashira.

Giyu didn't answer her. He kept running while thinking about the mission's priorities first.

"Since we've been given this joint mission, let's try to get along." Shinobu said, hoping to be on more friendlier terms with him.

"I'm only here to slay some demons." Giyu said, not even slightly interested to what she said.

"How callous of you!" Shinobu secretly remarked him even if she had to put on a smile to compensate for it.

"All right, then, let's split up here. I shall proceed from the west." Shinobu suggested.

"Agreed." Giyu accepted it. Within matter of seconds, Shinobu instantly vanished with incredible speed, leaving the Water Hashira to run off alone in the depths of the forest.

'It feels really cold from the west. Kocho must've felt it too. Just what was that?' Giyu felt a disturbance from the west and thought about it. He entrusted it to Shinobu to whatever it may be from there. After all, she's an Insect Hashira.


Returning to where Tanjiro and the elemental duo are fighting the huge brute, they had unleashed their strong attacks towards the Father Spider Demon with every ounce of their strength they can put in. However, it's not remotely enough to cut, pierce, or even sever at least any of his limbs.

"It's no good! The blade won't go through!" Tanjiro exclaimed, even with their combined forces.

The Father Spider Demon goes for another hard jab directly to Tanjiro's face. Yet, he had forgotten about Earth and Fire for a moment that he had let his guard down to focus only on Tanjiro. Fire joined with Inosuke to bring down their blades onto the raging arm the demon is going to attack Tanjiro while Earth added in his own mixed with his Earth Breathing.

"So hard!" Inosuke fought and struggled to cut off the arm. Fire scuffled, doing the same.

The Father Spider Demon easily repelled their attacks despite them outnumbering the demon. He sent the four flying in different areas and landed smoothly.

"I can't slash him even if I use an attack! What should I do? What should I do?" Tanjiro frowned and narrowed his eyes towards the big brute.

"Eiko wasn't kidding! Even at his base form, he's still a force to be beckon!" Fire remembered her words about the demon they're currently facing. 'I don't wanna imagine the other form she mentioned. If that happens, then we're basically gonna have a rough time with this demon!'

"Don't come near my family!" The Father Spider Demon hurled another fist at Tanjiro. "Stay away!"

Tanjiro braced for the impact since the demon is close to him. He closed his eyes to feel the blow he will about to receive, but it didn't arrive. He heard someone taking the blow for him and opened his eyes to see Earth defending him.

"Earth!" Tanjiro immediately caught him with his arms and carried him to the riverside. "You shouldn't have done that!"

Earth only chuckled. "And let you get hurt in the process? I don't think so."

The demon growled. Seeing that he got one of them made him thirst for more blood on his hands. Before he can attack any further, two shadows loomed above him and the demon glanced up to reveal two barbaric slayers coming down on him.

"What are you looking at!? I'm over here!" Inosuke shouted and readied his dual blades. "Curse you!"

"You hurt Earth!" Fire was angry that Earth took the impact for Tanjiro and he's ready to pay him back for that. "I'll cut you up for that!"

Earth gasped. "No! Don't!"

His plea fell on deaf ears as they rush downwards at the demon. The latter swatted them away like flies and they both slide on the water.

"Ouch! All that force with just one swipe of its arm! It's no good! I'm not at full power! Not to mention, the bleeding's making me stumble!" Inosuke uttered with fatigue overtaking his tone of voice.

"Ugh... I never knew he was that strong! Looks like I need to be more careful this time!" Fire grits his teeth and gripped on his sword with a fierce look on his face.

The demon did another snarl to the boys on the water and opted for them to run away from him. Fire would've fought back but seeing as Inosuke profusely bleeding and wounding himself, he'll hold it off for a while then he can unleash hell upon this brute.

Tanjiro and Earth ran from the side to give them the support they needed. It was Tanjiro that suggested which Earth would most likely agree to.

"Water Breathing, Second Form... Improved, Lateral Water Wheel!" Tanjiro sent a single volley of sliced liquid water directly at the tree, making it tumble towards the river.

Fire and Inosuke were both running from their lives away from the demon twice their size. Fire, with his enhanced hearing, heard a tree beginning to crash down on them from the side. He looked at the ones responsible for bringing it down and were relieved to see Tanjiro and Earth giving them backup.

"Inosuke, run faster!" Fire screamed and Inosuke mimicked. The tree came crashing between the boys and trapping the demon underneath it, earning a grunt of pain from the big brute himself.

"What was that? What's going on?" Inosuke said as he fell on his butt on the water with Fire beside him standing.

"Guys! Are you okay!?" They heard Tanjiro calling for their safety.

"We're good! Thanks!" Fire flashed them a thumbs up.

"That's great!" Earth heaved a relieved sigh.

'They did that?' Inosuke stared, wide eyed at them. 'That was some move, dammit!'

Rippling splashes and bubbles were seen where the demon is currently trapped under the fallen tree Tanjiro made. The Father Spider Demon struggled to escape from the heavy weight of the tree as he is gasping for air.

"Tanjiro! Let's get him while he's still under the tree!" Earth ushered Tanjiro on while they still have the chance to deliver their finishing blows at the trapped demon.

"All right!" Tanjiro then closed his eyes and begins to concentrate for his strongest final form of the Water Breathing Technique.

'This might be the only time I'll ever get to use this form.' Earth thought and went into his usual stance. 'The only technique I can fully focus on making it. The most powerful form of my Earth Breathing.'

With that thought out, Earth shuts his eyes completely and inhaled air with his breathing pattern in sync. He had never attempted to use this form before. It was when he had practice back at the wisteria household, not in the battlefield.

Fire and Inosuke watched with curious stares.

'Look at 'em! They're really putting this into effort! Let's hope they can bring this demon down!' Fire thought, although it was biased.

After a few more moments of getting their breathing in control, Earth and Tanjiro snapped their eyes open and prepared for their ultimate attacks. They jumped off the riverside and dashed over to the trapped spider demon with swords held firmly behind their backs.

'Total Concentration... Water Breathing/Earth Breathing... Tenth Form!'

As soon as they leapt into the air, the big brute managed to lift up the heavy log with raw strength, making their attacks hit only the log instead of the demon. They snarled at the failed attempt but kept doing it anyway to defeat the demon.

"L-Look out!" Inosuke shouted. Fire knew what he meant as the demon had thrown them using the log as a swinging mechanism. They yelped in surprise.

"EARTH!/KENTARO!" Both boys on the ground cried out for them simultaneously.

"I-INOSUKE!" Tanjiro yelled.

"FIRE!" Earth yelled in unison to Tanjiro.

"DON'T DIE UNTIL WE GET BACK! THAT'S ONE OF THE TWELVE KIZUKI!" Tanjiro shouted to get the message while falsely claiming the one they're fighting is one of the Twelve Kizuki.

"DON'T DIE! DON'T DIE! WHATEVER YOU BOTH DO, DON'T DIE!" Earth's yells were drown out by the growing distance between them.

Now it was just the two troublemaking Slayers in charge of bringing down the Father Spider Demon. Fire sweats profusely. Eiko's words echoed in his head. Apparently, it was suppose to be all of them that can defeat this demon.

Unfortunately, fate has other plans scheduled for them.

"This is not looking good..." Fire muttered, feeling a bit discouraged without Earth or Tanjiro with them. But at least he has Inosuke with him. Somehow, it didn't ease his worries a bit.

Speaking of the boar, the latter stood there, staring at the direction where the other two Slayers were flown to a great distance. Inosuke shivered a bit before bringing his sights at the demon again.

The Father Spider Demon growled menacingly at the both of them. Fear struck their hearts as they found themselves paralyzed in their spots. The only option for them now is to run away from his line of sight. The demon let out a loud scream when he brought his huge fist down on the two boys.

"Oh, crap!" They exclaimed.


Meanwhile, on the near depths of the forest lays a hanging house which formerly housed the Older Brother Spider Demon, which he was slain by Zenitsu and BoBoiBoy Ice. Speaking of Zenitsu, the poison had reached the next stage of shrinking Zenitsu nearly enough. His arms and legs are noticeably shorter than what they seem, leaving the clothing remains to be left there. They don't fit anymore.

It had been like an hour since this whole thing happened.

Ice watched with an intense worried look directly at his friend. Death's door is nearing his reach. No matter how many times he told himself that he'll survive, second thoughts always imbued his mind. He's not going to succumb to it. No way, no how!

Zenitsu's breathing is barely audible. He's trying his very hardest to stay conscious. Even with Ice here, Zenitsu is encouraged enough knowing he's not alone to suffer. He's very thankful.

"Keep holding on, Zenitsu." Ice whispered. He lifted up Zenitsu's sleeve and held on to his shrunken unpoisoned hand. He made sure to not freeze his hand despite Ice's chilly hand.

The spiders that were supposed to be frozen, melted and looked up towards the house, or more specifically, looking at Ice and Zenitsu with a somehow sad look. Even though their intellect was taken by being an arachnid for who-knows-when, they still displayed an act of sympathy.

His breathing slowly came to a stop.

"Zenitsu...?" Ice's grip on his hand squeezed. "Zenitsu... don't do this to me... Don't give up!"

Ice's eyes were leaking tears and kept holding on to his limp hand. He wouldn't want to lose his friend. Not yet!

Zenitsu really reminded him of his long lost best friend, Gopal. If he were to die, it would break BoBoiBoy. And he's not going to have it either way.

To his relief, he can see Zenitsu's eyes flutter open slightly. Ice figured he heard him to not take the easy way out just yet. With a relieved sigh, he sat back down near him to give him space. However, it wasn't long when Ice hears something flying in the sky.

'Were those... wings fluttering?' Ice fixated his eyes towards the moon. He envisioned a butterfly slowly swooping down towards them gracefully. A weird sight to behold. There were no butterflies to be seen in the forest, much less in the dense parts of it.

The butterfly's form had taken shape of a young woman flying towards them in a form of butterfly's wings, mostly because of her haori's butterfly pattern embedded. Her feet taps the roof where Ice and Zenitsu is at and she gave a slight bow.

'Who is she?' Ice found himself enthralled with this unknown woman.

"Yoo-hoo!~" Still resuming her position, she leaned her hand near her face and called out for Zenitsu. "Are you all right?"

Ice had taken note of her voice tone. She speaks in a soothing, clear, and sweetly manner. But there was some part of it that is really unoriginal. Her voice lacks any intent of politeness. More like it's forced.

"Who are you?" Ice spoke up.

"Hm?" Shinobu almost wavered her purple eyes to Ice. She donned her signature smile to him.


Tanjiro and Earth were still flying in the air after being thrown by the big brute himself. Tanjiro sees a chance to blunt the impact by doing a Breathing Technique.

"Water Breathing, Second Form!" He double grips his sword and water was clearly seen from the blade. "Water Wheel!"

He aimed his attack to a tree and successfully landed with minor setbacks.

"Tanjiro!" Earth cried out for him. Tanjiro heard and swerved to and fro to catch him from the ground.

The result was that Tanjiro had caught Earth, but due to the landing speed, it caused them to crash down to the ground. Earth emerged with a slight head trauma and Tanjiro getting hurt in the process with dust on his clothes.

"Ow..." Earth held his head in pain.

"Are you all right?" Tanjiro extends a hand to the fallen earth elemental. He accepted the gesture and the dark redhead raised him up from his spot.

"My head hurts but I'll be okay." Earth said to not make Tanjiro worry. If it were the other way around, Earth would have been fine and Tanjiro would've survive the fall due to his thick head.

'It's not like I wanted Tanjiro to get hurt because of me. I don't want to make him worry.'

Somewhere near them, they heard a piercing scream that alerted them both and gained their attention.

"I beg of you! Please stop!" A feminine voice cried and pleaded.

Both boys walked slowly to the source that situated near their location. They came to a full stop when they spotted two demons with the female demon kneeling down while covering her face and sobbing underneath and a male demon with webs tied in his hands and looking down on her.

"What are you two looking at?" He asked as he looked at the shocked duo. "This isn't some show, you know."

Tanjiro knew this demon isn't like any other. He answered. "Wh-What are you doing? Aren't you two allies?"

"Aliies? Don't put us in the same category as something that flimsy. We're family. We're joined by a powerful bond. And besides, this is between me and my sister. So don't interfere." Rui directs his webbing on them. "Or I'll carve you two up."

Tanjiro isn't intimidated by that fact. He knew what it's like to be family. The way he is treating to a family member is entirely false. The next thing he'll say will throw Rui off of his game.

"You're wrong! Whether it's your family or an ally, if you have a strong bond between you, then either one should be just as precious! Calling it flimsy if you're not related by blood... That's not true at all! Not only that, but those who have a strong bond give off the scent of trust! But all I'm picking up from you two is the scent of terror, hatred and repulsion! That's not what you call a bond! It's counterfeit! It's forged!"

Hearing his words caused everyone around to be surprised. The Older Sister Spider Demon gasped when she heard it, causing her to pause her crying. Rui's facial expression slightly became unsettled.

'Seeing him hurting the girl really agitated Tanjiro to the point he'd prove to him what a bond is about... That's maybe because the only family he have left is Nezuko.' Earth mused. He heard something from Fire not too long ago when he told him about the family's pretend roles to be biased. It's not something a family should do. Earth experienced it.

"You..." Rui muttered, visibly trembling in anger.

Earth heard footsteps approaching and turned his head to the side to see an unknown Demon Slayer entering the scene.

"Hey! Look at that, a demon that's just the right size. Even I can take down a kid demon like this one." He smirked and resume his basic fighting stance, sword in both hands.

"No! Just stop right there! It's not safe!" Earth attempted to reason the Slayer that the demon they're facing is dangerous.

"You can just back off! I want to take the safe route up the ladder. Since once you move up, you get more money from the top guys. My unit's practically been wiped out, but I'll slay myself a decent-sized demon and head down the mountain." The Slayer then charged forward to Rui. "Take this!"

"Don't do it! Stop!" Tanjiro yelled but it was all in vain. Rui raised his threads towards the Slayer and instantly, he got cut in multiple pieces, making his remains fall immediately to the ground.

'He just got killed instantly! By his threads! How did he...' Earth thought. An anxious feeling rose within him as he sees a Demon Slayer shattered to pieces in an instant.

"Hey, what did you say?" Rui asked to Tanjiro. They gotten their swords ready and fully faced Rui.

"Look, you... What was it that you just said?" A menacingly tone accompanied with a terrifying look. Normally a person would faint from fright just by looking at him and hearing him.

'What a horrifying sight... Only that look alone can send shivers down to anyone's spine! It's so intimidating! The air here just got heavy all of a sudden! Is this really the Twelve Kizuki Fire told me?' Earth lightly flinched when he sees Rui's intimidation factor.

"Tanjiro, be very careful with this one. He isn't some demon we faced in the past!" Earth whipser-yelled.

"I get that! Let's just hope Inosuke and Fire are still fine while we're dealing with him!" Tanjiro replied.

"Hey, you... What you said just now... Let's hear you say it again." Rui asked none other than Tanjiro. "Come on. Say it, will you?"

"Sure! I'll repeat it as many times as you want! Your bond is forged!" Tanjiro shouts with determination.

Earth frowned. He did not like the look on Rui. Not one bit. He spared a look to the female spider demon. She's still kneeling on the ground, not looking at them.

'Why am I getting the feeling that things are about to get worse?'


Fire and Inosuke retreated somewhere beyond the location from the river and both hid behind some trees for a place of regaining their lost breath. The masked boar breathes heavily due to his wounds taking a great effect on him. Fire breathed in the same manner by having to run away from the Father Spider Demon.

Meanwhile, the big brute is on the lookout for both of them.

'Damn! Inosuke left behind a trail of blood that leads right to us!' Fire worriedly feared for the worst when the demon had already found them hiding behind some trees thanks to Inosuke's blood trail. The demon gnarled loudly, indicating that he is now going in for the kill.

"O-Oh, crap!" Inosuke cursed and feels the demon slowly walking towards their spot.

"Inosuke, you still holding up alright?" Firespouted little worries to the boar. Inosuke gave him a slight glare.

"I don't need you keeping an eye on me! I'm fine without you!" He spat at him. "But still, how pathetic is that we are hiding ourselves from the demon!?"

"Keep your voice down!" Fire tried to keep Inosuke's voice to a down low.

"Argh! We gotta come up with a way! How do we slash someone who's sword-proof?!" Inosuke is starting to panic. It's not everyday Inosuke is scared about something.

"It's okay man. We'll find a way to kill that demon." Fire said. "But for right now, we need to worry about not getting ourselves kilâ "

The demon had smashed their hiding spot, which resulted them to sprint away to another place they can think of. Inosuke panted really heavily.

"This is bad! This is really bad!" Inosuke nervously uttered. "Until... Until they get back, we gotta somehow..."

Then something clicked in him. Inosuke completely stopped in his position, making Fire stop in his tracks and gaze at Inosuke.

"What's going on? Why'd you stop?" Fire asked.

The reply Inosuke gives him is different.

"WHAT THE HELL KIND OF ATTITUDE IS THAT?!" Inosuke screamed.

"Huh?!" Fire is entirely confused. He wasn't sure if that statement is for him or for himself.

Inosuke did the unthinkable and charged in, straight first to the demon they're running away from.

"Inosuke! The hell is wrong with you?!" Fire reluctantly joined his side.

"DON'T MESS AROUND, DAMMIT!" Inosuke yelled and lunged at the demon then planted one of his blades to the demon's arm.

"CURSE YOU!" Inosuke exclaimed and banged his sword's blade with his other sword repeatedly and ranted. "LOOKS LIKE I GOT INFECTED BY TONTARO'S GERMS! MESSING AROUND LIKE THAT... THAT WAS WAY TOO CLOSE A CALL! USING MY HEAD?! THAT'S SO NOT ME!"

Fire sighed. Things aren't easy with Inosuke around.

"Looks like we're doing this the old-fashioned way!" Fire also did the similar thing and implanted his sword on the demon's chest.

"Fire Breathing, First Form, Flaming Combustion!" With his sword's blade inside the demon's chest, Fire had produced flame inside his opponent making the skin burn and rapidly spread around his entire body. The demon harshly let out screams of pain and tried to endure it all.

"Do it now, Inosuke! Slice his arm!" Fire encouraged the wild boar. Hearing those words, Inosuke fueled his strength to give one mighty slice and the arm gave way, making it fall down into the ground.

"All right! Slashed you!" Inosuke said proudly.

The demon recoiled when he senses lots of injuries in his entire body. One would be his visibly sliced arm and multiple 3rd degree burns erupting out of his skin.

'If this is how the demon's base form is like, then the transformation would be disastrous! I gotta finish this before it's too late!' Fire hurriedly gathered more air to ensure this attack will end the demon.

"Hey! Stop doing that!" Inosuke headbutted Fire, causing him to spew out saliva.

"Wh-What... What the hell are you doing, Inosuke?!" Fire angrily asked while holding his aching stomach.

"I'm gonna kill this demon myself! I don't need you doing it for me! Now get outta my way!" Inosuke puffed out smoke from his mask's nostrils.

Fire couldn't believe what's he's hearing right now. He wouldn't let him have his way. "Don't be crazy! You saw how strong this demon is back at the river! What chance do you get if you fought him by yourself?!"

"Well it's gonna be really simple! If you can't slash something with one sword, all you gotta do is pound it with another sword! I mean, look! I have two swords!" Inosuke boasted, then let out a hearty laugh. "I'm the almighty!"

Fire facepalmed. "That's not how it works, you idiot! You only did that because of my help!"

"That's bull talk!"

"Oh yeah! Look who's talking who, you dumbass!"

"I can kill this demon with my bare hands if I have to!"

"Not without me, you're not! You'll get yourself killed!"

The demon, having heard of their arguments, suddenly did the unexpected and ran away from the duo. It left them with confused expressions, wondering why the demon suddenly took off like that.

"Huh?! Are you running away on me?! Hey you! Come back here, dammit!" Inosuke pursued the fleeing demon, leaving Fire alone.

"I have a bad feeling about this." Fire nervously said and followed after Inosuke. A demon shouldn't run away like that. There is something very off from that and Fire didn't like it one bit.

He hoped Inosuke wouldn't do any risky tactics when he manages to catch up to the demon.


Rui swings his threads towards the moving Demon Slayers as they are obviously trying to avoid getting sliced into bits by the threads' unknown strength. He managed to graze his threads onto their skins, letting blood trickle down their faces. One of the threads hit Earth on the arm, making more blood to let out.

"Aaaaahhhhh!!" Earth writhed in massive pain when he felt his arm bleed. It's a very good thing his Demon Slayer uniform protected his arm from being cut off but still enough to cause blood to spew. Earth wrapped around his wound with a spare bandage he had in store inside his haori.

"I just want to let you know... I don't kill you both in one blow. After ripping you to shreds, I'll carve you up." Rui dropped them a reminder.

"But... if you take back what you said just now, I'll do you a favor and kill you at once." Rui suggested to Tanjiro.

"As for you, boy." He turned to face Earth. "You'll joining with your friend if you don't comply with what I said. However, if you don't, I'll be sure to make you suffer one last time before killing you."

"I won't take it back! What I said was the truth! You know who's not making sense? It's you!" Tanjiro said in-a-matter-of-factly.

"It's clearly you who is mistaken! You can never understand what family truly means until you knock some sense into yourself! Rui!"

Hearing Earth mentioned his name made Rui widened his eyes by a fraction. The webs in his hands barely shaken.

"Boy... How in the world did you know my name?"

Earth realized what he just said and covered his mouth. It was a mistake to call him out like that. Fire had told him that the demon they're battling is Rui. Fire told Earth to be very careful not to say his name out loud or else, Eiko's life would be endangered if he found out she betrayed him.

Rui noticed the lack of response to his question. He slowly pieced together the silence and the statement Earth made. It is making a little bit of sense, but then he realized. Someone in his pretend family had spill the beans. It wasn't the Older Brother Spider Demon since he find it very unlikely, it wasn't the Older Sister Spider Demon since she's right here, it also wasn't the Father Spider Demon since he's narrow-minded.

He came to the only conclusion.

"Mother..." Rui quietly said.

The Older Sister Spider Demon trembled when she felt her brother's aura menacingly getting heavier. She found herself frozen to her spot and looked at Earth of what he had done.

"Earth, I detected a scent of vengeance and betrayal far stronger than before coming from that boy! Did you... say something bad?" Tanjiro felt the tension arising in the atmosphere. Earth switched his attention to Tanjiro. The former is dead worried because of one fatal mistake.


Turning back to Inosuke and Fire, they were still on the lookout for the demon who ran away from them. It was very odd, but then to Fire, he feared for the worst of what's going to happen.

"Damn it, Inosuke!" Fire blamed the one who was responsible for not letting him finish off their opponent. "Thanks to you, I should've killed that demon minutes ago!"

He followed Inosuke behind as he kept searching for the demon. He got down on one knee due to his injuries getting to him.

"I'm telling ya! This doesn't hurt! What doesn't hurt, doesn't hurt!" Inosuke stubbornly said.

"Would you cool it down for a minute?! We still need to find the demon!"

Inosuke stared at Fire panting for air and gave a glare to the fire elemental. He tried to extend a hand to the boar but ended up swatting his hand away.

"Why are you still getting in my way?! I said I didn't need your help!" Inosuke shouted. "I would've handled all of this myself! Stop trying to give me the help I don't want, you damn moron!"

After everything Fire tried to resist himself, he finally snapped.

"ME?! GETTING IN YOUR WAY?! INOSUKE, YOU ALMOST DIED FROM THE LAST DEMON WE FOUGHT! YOUR WOUNDS ARE WHAT'S CAUSING YOU TO EXHAUST YOURSELF! YOU TRIED TO KILL ALL THOSE DEMON SLAYERS BACK AT THE FOREST BECAUSE WE TOLD YOU NOT TO! AND YOU DONT WANT MY HELP?! THEN FINE! IF YOU THINK I'M GETTING IN YOUR WAY, YOU BETTER THINK AGAIN! I SAVED YOUR ASS FROM GETTING KILLED A BUNCH OF TIMES AND I EXPECT NO THANKS FROM YOU EITHER! YOU THINK YOU'RE ALL THAT POWERFUL?! THEN HAVE IT YOUR WAY! I'M DONE WITH YOUR SHIT TODAY!"

He calmed down after his enraged outbursts. Inosuke hung his head down and thought about it for a minute. Fire spoke what he needed to because Inosuke annoyed the hell out of him for the last time. He almost felt bad for doing it to the boar. His pride was in the way of making smart decisions. Fire shouldn't have shouted at him the second time.

But of course, Fire is still angry. His outburst didn't exactly calm his boiling anger. Eventually, his hearing senses picked up whimpering and shivering from up top. Glancing his head up, he found the Father Spider Demon holding on tight to a tree branch while shaking what presumably would be; fear.

"Hey!" Fire exclaimed. "You damn coward! Come down here and fight me! Trying to run away, you think you're that tough, huh?! I'll burn you into millions of crisps!"

The big brute began shaking at a rapid pace. It doesn't sound right to Fire and he put on his guard, not liking the sounds the demon is making.

The big brute underwent a different transformation. His dark purple skin melted and was replaced with a greyish-metallic version of his previous skin. His body size buffed up and his arms had multiple spikes. Razor sharp teeth

"Holy crap..." Fire's breath left him from the horrifying sight in front of him; the demon.

No... This isn't a demon.

It's a monster.

'We're... We're gonna die, aren't we?' Fire trembled. Inosuke also trembled at the monstrous sight as well. 'I'm shivering down to my bones. This never happened to me before, right?'

The monster growled. It was only a growl but it left them with a sense of dread and defeat. They're stances ceased, and they're too focused on the thought of dying to even noticed their arms sinking gradually to their sides.

'We can't win... we're gonna die... we're gonna be killed...'

The monster had his fist ready to punch them.

'Is this it...?'

He thought, like this would be their last moments. In the midst of their train of thought, one memory raced in his head and recalled it.

First, there was Tanjiro, back at the wisteria house when he was still BoBoiBoy.

"BoBoiBoy, remember two years ago? That we'll always be together until the end? I'll still keep holding on to that promise until Nezuko finally becomes a human again." He smiled in his memory.

Second, there was old lady Hisa, back at the wisteria house and to the entrance before seeing them take off on their mission.

"Always live your lives with great pride. I wish you luck in battle!" Her words of wisdom resonated in Fire's and Inosuke's heads.

And finally, the person Fire has been hoping to see again, Tok Aba.

"I'll be waiting for you to come home, BoBoiBoy. Good luck out there!" Tok Aba said as he watched his grandson going inside the commander's spaceship for another mission.

The memories served as a driving force for them to bring back their battle spirits again.

"No...!"

Fire grasped onto his sword tightly.

"No way I'm gonna lose today!"

He resume his stance and Inosuke did as well.

"I'm not gonna lose! No way am I gonna lose!" Inosuke proudly stated his next line. "I'm Inosuke Hashibira of the Demon Slayer Corps! Just bring it, you dirtbag!"

Fire smirked at him. At least now he finally has the courage to face the monstrosity of a demon.

'I'll apologize to him later. But for right now, it's demon slaying time!'

His thoughts were cut out when a blurred fist sent them ricocheting into some trees. Neither of them knew what happened but knew it was the work of the monster's punch's force.

They crashed into a tree and soon, the monster quickly caught up to them in an instant and hurled another punch towards them. Inosuke front flipped in the air while Fire crouched down to avoid getting hit. Inosuke is in a pretty good position to deliver a strike to the monster's nape area.

"Beast Breathing... Fang Three, Devour!" He swung his dual blades in an X fashion but the blades not only do much damage to the nape area but only snapped his swords due to the monster's steel-like body.

"It snapped!" Inosuke gaped. His swords were now broken. The monster swatted him away like a fly and crashed into a tree.

'Oh, crap! I failed to go on the defensive with my breath attack!' Inosuke is having trouble getting back up.

"Inosuke!" Fire sensed Inosuke's life in peril and tried to lunge at the demon.

"DAMN YOUUUUUU!!!" Fire inhaled sharp oxygen to the point he inhaled every air around the area.

"Fire Breathing, Second Form... Torching Slash!" He swung his basic offensive slash at the demon. It didn't do much but left a burn mark on the demon's chest.

His world was blurred when he felt a hard jab directly on Fire's abdomen that caused him to vomit out blood. Fire then crashed into a bunch of trees and hit his head on the tree bark. The impact rendered him unable to move now.

"Ino... suke..." Fire robotically reached out for the wild boar. He felt his head getting crushed then lifted up by the monster himself. He then proceeded to grab Inosuke's head and together with both boys on his hands, he crush their heads slowly.

"Don't come near my family! Stay away!" The monster said as if that's the only sentence he knows.

"I'm not gonna die...!" Inosuke blurted out. "Beast Breathing, Fang One... Take this! Pierce!"

Inosuke stabbed his two broken swords into the monster's neck yet, he didn't flinch nor feel the pain.

"Get a load... of this!" Fire's idea is to stab his sword onto the monster's eyes hoping it would work and as a last ditch effort to do any sort of damage. However, the monster crushed his head enough to make him drop the sword. Fire desperately tried to claw his way out of the death grip.

To no avail.

Inosuke's attempt didn't go as what he had in mind. The monster then slowly tortured them by crushing their heads until they pop.

Their bodies twitched.

Fire's hands stopped clawing their way out.

They're going to die.

Die but never forgotten.

"I'm sorry."

Inosuke experienced his life flashing before his eyes.

"I'm sorry, Inosuke." A woman, presumably to be Inosuke's mother, cried on Inosuke as an infant wrapped in a loincloth and on her arms.

Images flashed into him. On showed Tanjiro, Zenitsu, and BoBoiBoy all looking at Inosuke with a look of empathy.

Another is old lady Hisa back at the wisteria house offering him and BoBoiBoy their kimonos.

And lastly, it showed him pointing up on the sky and a dragonfly on his index finger.

"I want at least you to survive, Inosuke." She dropped her son down on the cliff and unheard words escaped fron the mother.

"Wh-Who are you...?" Inosuke muttered weakly and blood flooded out of his mask.

Fire widened his eyes from seeing Inosuke spewed out a huge amount of blood out from his mask. For seeing him this lethally wounded brings an unspeakable emotion out from Fire. Combined with the situation they have with the monstrous demon, that too sparked a reason to save Inosuke from getting killed.

On his wrist, his power watch glowed. On the screen, labels are shown: Infusion complete. Secondary tier and Third tier form transferred to host. Activating desired element.

Blaze.

A surge of heat made the monster let go of his right hand and tried to cool down the fiery feeling. Although, it didn't leave his hand as the fire is still there and melting his hand immediately.

He then grabbed the sword that was on the ground and sliced off the arm that was holding Inosuke by the hand. Inosuke dropped down to the ground and was knocked out unconscious.

The demon recoiled back and took a good look at the boy he was holding on his right hand. His sword was violently swarmed in flames. His haori had changed from patterns of fire into the shape of a fire this time. His eyes are a raging redish-orange. He glared intensely at the demon.

"BOBOIBOY BLAZE!" Once he shouted, a wave of flamed erupted behind him, making the grass around to light up in small embers.

The monster flinched, completely baffled by the new change. Soon after that, he regenerated his lost limb and went towards the fire elementalist.

Blaze dodged with ease. Thanks to the watch's failsafe recovery, he can swiftly take on the monster with no worries.

"Over here!" He lured the monster away from Inosuke so that he won't get hurt in the process. The monster took the bait and went after the blazing Demon Slayer. Once he catches up to him, the monster brought down to of his fists directly above Blaze.

"Blaze Breathing... First Form... Explosion: Blazing Geyser!" Once Blaze leapt away from being pummeled to the ground, the last spot he was at had erupted a giant geyser of flames accompanied by an explosion that came with it. The flames consumed the monster completely but wasn't enough to completely evaporate him into existence.

The monster recovered slightly from the attack and went for another blinding punch towards Blaze. The attack was a bit sluggish and Blaze had enough time to move out of harm's way.

"Too slow!"

Blaze acrobatically went behind the ginormous brute and jumped up to finally end this monster's life with his last attack.

"Blaze Breathing... Fourth Form... Improved, Sacred Magma Slash!" The sword had temporarily enhanced to morph into a form of lava and swiftly struck it to the monster's body. He screamed in extreme pain and blood seeps out from his sliced parts of his body. Due to humidity around the area, it caused only a few trees to cause fire and quickly died out due to Blaze controlling it.

The monster let out one last scream until he is completely dead. The lava remains had consumed his metallic flesh and finally, he evaporated into ashes.

The battle of the Father Spider Demon is finally over.


I'm back with another chapter, minna-san!

Well, how was it? Good or bad? Either way, I had fun writing it as much as I hope you had fun reading it too!

The "Blazing" entrance was a bit rushed and I wasn't good with fight scenes that much. But I managed. I don't know, did I manage better? I guess so. But maybe the details I put will suffice for now.

Anyways, I'll see y'all in the next chapter!

~ s a y o n a r a ~

And by the way, to all you moms who are probably reading this (...which I find it very odd and unlikely but hey, I can't judge xD) and to all the people who treated others like a mom here in the internet and the moms themselves who they aspire to be. (Lmao, what am I saying xD)

Happy Mother's Day!
