Meanwhile, on Kiba's battle with Karlamine, the former becomes surprised when his opponent destroyed his sword.
"Shit! My Holy Eraser!"
Seeing his weapon shatter made Karlamine smile.
"Unfortunately for you, that weapon won't work on someone like me!"
Kiba kept his ground, gripping the hilt of his blade tightly.
"Oh really?! What about this one?!"
He focuses his attention on the top of the hilt.
"Freeze! Flame Delete!"
What happened next made Karlamine adopt a look of shock. After the top of Kiba's hilt shined, blocks of ice began forming upwards and took on the shape of a sword's blade. Afterward, the ice broke apart, making a fresh new white blade.
"What?! You've gotta be kidding!" Karlamine retorted. "There's no way you can have two Sacred Gears!"
Karlamine lifts her flame engulfed sword above her head and attempts to slash down on Kiba. When Kiba blocked her attack, she widens her eyes again to see shards of ice creep along her sword and destroy her blade, leaving nothing but the hilt.
Growling in anger, she throws the hilt to the side and unsheathes her dagger, engulfing that one in flames afterward.
"No matter! I still control flame and wind, as do all from the house of Phenex!"
Karlamine then slashes her dagger downwards at Kiba's sword, destroying that one too.
But he didn't see this as a problem, Kiba only smirked at her as he cocked his hilt to his right side.
"Replenish Calm."
Upon saying those words, Kiba's hilt created another sword blade that had an open diamond-shaped tip with a triangle tip on top and two points at each bottom side.
Karlamine was flabbergasted at the sight of his new blade. Before she could say anything, Kiba held his sword in front of her and had a small black hole appear in the middle of the open diamond of the sword.
Suddenly, the black hole started to absorb the flames off of Karlamine's dagger, causing her to widen her eyes in bewilderment.
"Dammit! How many Sacred Gears do you actually have?!" Karlamine asks him in frustration. "Are you a Sacred Gear possessor who takes Sacred Gears from people and use them as your own?!"
"Nope! It's not that I have multiple Sacred Gears, I simply have the ability to make them at my will! I possess Sword Birth! Have you heard of it?! With it, I'm able to create any demonic sword I choose from!"
After removing the flames from Karlamine's dagger, Kiba places his left palm on the ground and summons a spike bed full of swords, making Karlamine jump back and look on in shock at the number of swords he created on the ground.
"Dammit all!"
Izuku took a quick look at the fight between the two Knights and smiled at his friend.
'I figured he can handle himself.'
"Oi!"
Izuku simply shifted his eyes right when he heard Isabela call to him while charging at him with her fist cocked back.
"Never turn away during a fight!"
But Izuku easily caught Isabela's fist just before it could come in contact with his cheek, making the latter widen her eyes in surprise at how he was able to catch it while barely looking at her direction.
Giving her a stern glare, Izuku grabs onto Isabela's wrist and pulls her towards him. When she got close enough to him, Izuku punches her in her left cheek, knocking her back four feet. He then stares at his Boosted Gear.
"Come on… One more boost…"
'Ddraig I swear stop taking so damn long!'
{Boost!}
'Screw you, it's not my fault you have less strength from before'
Ddraig inside of Izuku's mind with the latter just sighing while getting ready, having boosted enough during his fight with the masked Rook, Izuku extends his Boosted Gear embedded hand outwards and conjured a red ball of power from the palm.
{Explosion!}
Isabela goes in to land another punch on Izuku But before she could manage to do that, Izuku punches the red orb, making a huge red beam shoot at her at high speed.
"Shit!"
Isabela was able to duck down in time before she could be engulfed by Izuku's Dragon Shot. As the beam traveled far enough, the attack blew up a set of trees, followed by an explosion cloud engulfing them.
"What the…" Izuku said to himself, confused on how it was able to cause this much damage. "I could've sworn I've held back a lot of power. That looked like it could take down a Queen or two."
Isabela gets up from the grown and looks at Izuku with narrowed eyes.
"I can't afford for him to use that attack again. I gotta take him down now!"
Seeing Isabela charge at him again, Izuku decided to resort to plan B.
'I was hoping I'd save it for later use against Riser and save energy, but I guess I'll have to use my explosive aura again.'
Izuku then dodges a punch from her right fist and grabs onto her arm with his left hand. He then opened his right hand and struck her in the stomach lightly with his palm.
"Uh… was that supposed to hurt..?" Isabela asked him with a confused expression, only for Izuku to jump back from her and have her notice the black and red magic seal on her belly.
"Not yet!"
Snap!
*BOOM! BOOM! BOOOOOOOOM!*
"GUAAAAAAAAGH!"
Isabela fell to her knees and held onto her stomach in pain.
"E… Explosive magic?!"
Seeing her unable to get up, Izuku took that moment to slowly walk towards her and finish the job. After approaching her close enough, Izuku conjures another red orb from his Boosted Gear, this one being smaller than the previous one to avoid using too much power.
When Isabela lifted her head up, she was surprised to see that Izuku had softened eyes and a gentle smile.
"You fought well, Isabela," Izuku says kindly. "But this is where you retire." Izuku cocks his left fist back to punch the orb. "I hope we can see each other again."
Isabela widens her eyes with a light blush that could only be seen on her left cheek because of her mask.
'He's so kind to me… Why..?'
Izuku then punches the tiny red orb, launching his Dragon Shot at the Rook. Isabela lets out a scream of pain while she's engulfed by his attack, eventually disappearing in a bright light.
Ravel looks on in shock as she witnesses her defeat.
"Isabela!"
"One of Riser-sama's Rooks retires."
Izuku lets out a breath, glad that he was able to defeat her.
"Why are you being nice to the enemy?"
"Eh?"
Izuku turns around to see Koneko with her arms crossed in front of her and narrowed eyes.
"...well it's Because they're not the ones I'm holding it out against. The one I want to smack some sense into is the Yakitori Bird Brain Motherfucker with Stick so far up ass that he might need surgery after to just take it."
Koneko raises an eyebrow at his answer. She then shrugs her shoulders.
"Just don't make a habit of trying to befriend enemies."
Izuku just chuckled at her response while patring her on the head which caused her to blush.
He then looks towards his Boosted Gear in thought.
'Oi, Ddraig, do you think I can still boost myself up without going burst?'
{You should be able to without risking it, partner. After all, you've only boosted once during your battle with the three Pawns and boosted about four times to make a powerful enough Dragon Shot. You shouldn't have to worry about risking a Burst. Besides, you did train very hard with, and without the Boosted Gear, so you're far from risking that happening to you.}
Izuku nodded his head at his gauntlet.
'Okay. Good to know.'
"Oi! Foot soldier!"
Izuku lifts his head up to see Ravel calling to him with a cocky smirk. He raises an eyebrow when he saw her point to her right.
"Just a heads up," Ravel continued. "You may want to look at this."
Izuku followed where Ravel was pointing and widened his eyes in shock.
"What the hell!? Asia! Rose!"
Rias could be seen carrying Asia in her arm while flying down to the top of the new school roof. Landing, Rias shoots Riser a glare.
"Dammit!" Izuku curses, seeing the three at the rooftop. "Riser's up there too!"
Kiba shares the same narrowed eyes as Izuku.
"It looks like he anticipated our move."
"So, I'm assuming you knew I was planning to attack you directly?" Rias asks Riser as she retracts her Devil wings and keeps Asia behind her.
"Ha! A virgin should never underestimate one with this much experience."
Rias rolls her eyes.
"How comforting. You're as vulgar as ever."
"The Princess of Ruin, Twilight Healing," Ravel began scanning the Gremory Devils one by one with a smirk on her face, moving on to the rest of them with every shift of her blue eyes. "Priestess of Thunder, Sword Birth, and Boosted Gear, with a rather menacing black and red aura"
Ravel lets out a devious giggle before continuing.
"Such grand-sounding names when they're all together." She then points a hand at herself. "However, we are Phenexes; immortal birds! And you-"
"Cannot defeat you. Blah blah blah! I get where you're going with this!"
"Yeah," Koneko agrees while glaring at Ravel. "You're sounding like a clichéd villain right now."
Ravel twitches in anger when she heard Koneko call her that.
"Grrrrrr! Don't you two get it?! Your situation here is completely hopeless!"
All Izuku could do was sigh before staring back at her with a stern expression, "I personally wouldn't say that, sister of the Yakitori Bird Brain." Ravel twitches her eyebrow.
"Everybody's got a weakness, especially you Phenex birds. You say you're immortal, but really, I find you to be about 80 to 90% immortal, as you can still die, are still weak by Holy and Light powers, and a nitpick from me, you're underestimating us way too much."
Ravel lets out a yell in rage, getting fed up with the Pawn's words.
"Oh yeah?! And exactly how are you Gremory Devils going to defeat my brother, huh?! Beat the living shit out of him until he's out cold?!"
"Yup."
"Ditto."
Ravel stares at them with a flabbergasted look. Her left eye twitching while processing their responses. Deciding that she's heard enough, Ravel sets her angered gaze at the catgirls.
"Ni! Li!"
The catgirls, the one with blue hair, Ni, and the one with red hair, Li, make a meowing sound in response to her.
"It's time you show those two idiots how wrong they are of their current situation!"
In her command, the catgirls let out another meow as the two charge at Izuku and Koneko.
Izuku wasn't worried, and neither was Koneko. When the former saw Li going for a dive kick at his stomach, he grabs her leg, catching her by surprise, and throws a right hook at her face.
"NYAAAH!"
As Izuku's fist makes contact with Li's face, she fell backwards from him and tumbled six feet away from him.
"Hey! How dare you hurt my sister?! Nya!"
Ni went in to hit Izuku with a shoulder charge but was abruptly stopped when she too got punched in the face by Koneko, who was glaring at the catgirls rather darkly.
"Piss off."
The catgirls got up and shot a glare at the two Gremory Devils. Before any of the two could make a move on Issei, a voice cuts them off.
"Move it! He's mine!"
Everyone turns to see Siris in the air, unsheathing her large sword and charges at Izuku with her weapon above her head. When she got closer to him, Izuku side steps right in time to dodge her slash once she landed in front of him.
Grunting, Siris tries to take him out again with a horizontal slash, only for Izuku to jump back from her, dodging that attack.
"Oi! Koneko! Can I leave the catgirls to you?!"
Koneko nods in response while glaring harshly at the catgirls.
"Sure."
Izuku smiles at her in response, not being aware of her scowl since her back was facing him.
"You're attention should be on me, Izuku-chan!"
"Eh?"
'Why 'chan'?'
He thought as he turns back to Siris and raises an eyebrow at the honorific she gave him.
"Chan?"
Siris flinches and shifts her eyes away from him as her cheeks tinge pink.
"N-N-Never mind that and fight! You did promise to fight me too, you know."
Izuku blinks at her for a couple of seconds before sighing.
"Yeah. No worries, I remember."
Izuku then whistled towards Kiba who simply nods his has and summoned a large seed towards Izuku's direction that planted on the ground near the boy, Izuku then grabs the hilt and holds it in front of him and gets in a fighting position with the blade.
Seeing that he's ready, Siris charges towards Izuku and clashes swords with him, beginning her battle with him.
