Both Izuku and Riser let out a battle cry as the two charge at each other. Izuku notices that Riser was aiming his fist toward his gut. As the two were three inches close, Izuku uses his quick reflexes to dodge his punch and slash at his back, earning a roar of pain from Riser.
While the slash did hurt Riser, and a small amount of blood did spurt from the cut, the injury was immediately healed by his regeneration. However, Kiba made a discovery on how it was healed while watching the two battle.
"Riser's injury from Izuku's Blade took longer to heal than the ones from your attacks, Buchou."
"But of course," Rias replies while keeping her eyes on the two fighting each other, with Izuku and Riser switching from offense to defense every five seconds. "What Izuku is doing, he's somehow using his aura to coat the blade and give its opponents a long lasting effect that will harm them badly"
Riser turned around to face Izuku after recovering from the latter's attack. He then notices that his Scale Blade was now engulfed in his black and white aura.
"Heh! You might as well get rid of that aura, boy! Riser is fully aware of what it could do to me!" He then points towards Izuku's gauntlet. "Same goes for your Boosted Gear! It can double your power every ten seconds and can transfer power to your buddies!"
All Izuku was keep his stare on the Phenex Devil, not at all phased by his words.
"I don't need you to tell me how to fight! Dragons"
Izuku then lifts his aura engulfed weapon above his head and then slashes it downwards.
"…Wrath!!!"
"It's no use!"
Ravel and the Gremory Devils look on to see how big the Red crescent with a white outlining was, amazed by what he can do with his aura. As for Koneko, she watched the aura with the same eyes she had when she first witnessed her senpai's Dragons Wrath.
As a vertical shaped crescent rushed towards Riser, he dodges to his left, smirking at how easy it was to dodge such an attack.
"Heh! Like dodging a boulder!"
*SHFF!*
"!"
Izuku appears behind Riser with speed similar of a knight, surprising the latter!
'Shit! It's his promotion! But the speed is much faster than a Knight's and Queen's combined!'
"Don't be distracted by how you were able to dodge it easily, Riser."
*SLASH!*
Izuku curs off the arrogant pricks legs with a horizontal strike of his Blade. Blood spurts from Riser's stubs for two seconds before his regeneration began to make new legs. Izuku took that chance to punch the Phenex Devil's skull with a downward punch from his left fist, slamming his face on the ground with a loud thud.
Izuku then jumps away from Riser in case he was planning to fry him while on the ground, keeping his stare on Riser.
After his legs were reconstructed, Riser gets up from Izuku's punch and tries to keep balance on the rooftop. After getting his balance, Riser looks at Izuku, or more particularly, his Blade.
"You sly Devil," Riser says with gritted teeth. "If you didn't have that sword with you, then this victory would go to Riser."
Izuku just rolled his eyes with Ddraig just sighing at the Phenex's arrogance.
'Partner for the love of things that are bloody and gory...PUT THIS WASTE OF ARROGANT PIECE OF SHIT IN HIS PLACE!!'
Izuku just smirked, 'With pleasure'
While looking over to Riser.
"Really? Is that how you see it?" Izuku asks as he sheathes his weapon and puts his fists up. "Okay then, let's put that to the test."
"With pleasure!"
Izuku stood his ground as Riser charges at him with his Phenex wings sprouted from his back. As he got closer, Riser aims his fist towards Izuku's face, only for the latter to dodge to the right.
Seeing that he dodged it, Riser attempts to counter with a backhand. Seeing it, Izuku grabbed his fist and threw his own at Riser, punching him in the face.
Riser spun around from the impact of his fist but was able to stop himself and attempted to kick Izuku in the stomach. He then dodges and throws a punch towards Riser's face, only for the latter to dodge the punch. It was rinse and repeat with their strikes, Izuku dodging and blocking his punches and kicks while taking some blows, and Riser, doing the same.
After dodging another attack from Izuku, Riser grabs onto his arm and attempts to break it.
"Now I gotcha!"
Riser then lets out a yelp when Izuku sweeps his right leg across Riser's, causing him to fall over and let go of his arm. While he was still airborne during his fall, Izuku grabs him by the collar of his shirt and balls his right hand into a fist, slamming it hard into Riser's gut.
"BWAAAAH!"
Riser spat out a small amount of blood due to the impact of Izuku's punch. As Riser sees his blood fall on the ground, his eyes start to develop rage.
But before he could do, or say anything, Izuku removes his fist and opens his hand to where the palm can be shown. He then proceeds to strike Riser in the chest, and stomach multiple times while keeping a good grip on his collar. While he was hitting him with his palms, Riser didn't pay attention to the seals being planted on the areas he's attacking.
'Okay, hopefully, that's enough seals.'
Nodding to himself, Izuku kicked Riser in his stomach hard enough to knock him away from him by six feet.
As soon as Riser gets back up from the kick, Izuku snaps his fingers and watches the magic happen.
As he did so, Riser notices the black and white seals on his torso glow.
"What the fu-"
*BOOM! BOOM! BA-BA-BA-BOOM!*
"GUUUUAAAAAAAAAAAAGH!"
Riser screams in pain as his body becomes engulfed by the explosive aura from the seals.
"Onii-sama!"
Ravel's eyes widen in fear as she sees her brother suffer the explosive attacks from Izuku's aura, the same aura that she witnessed taking on the from of a dragon from behind Izuku earlier at the club room.
"Ara ara! Izu-kun's explosive magic must've caused a great deal of damage for Riser to scream this loud," Akeno comments while staring on at the sight of the explosion.
Kiba nods in agreement.
"But whether or not that's enough to finish him off is what we have yet to find out."
While Kiba and Akeno were watching with narrowed eyes, Rias, Asia, and Koneko looked on at the scene with softened eyes.
"Izu…"
"Izuku-san…"
"Izuku-kohai…"
While the explosives have stopped going off around Riser, the red and white aura was still roaming around the area, leaving his current condition unknown until the aura clears up.
After ten seconds of waiting, Izuku and the Devils watching see that the aura has evaporated, revealing a bleeding Riser Phenex.
Riser was panting heavily as he could feel pain all over. When he scanned his eyes down his body, his eyes widened to the size of saucers when he saw how badly damaged he was, thanks to some of the aura stuck onto him like glue.
But what made Riser angry, was the fact that blood, his blood, was all over the rooftop due to the damage he took from Izuku's explosives.
As Riser slowly gets up from Izuku's magic attacks, he still kept his eyes on the injuries the red and white aura prevented his healing factor to heal.
His eyes widen in anger, followed by grinding teeth of rage as he witnesses his blood covering his body.
"Blood… My noble blood, spilled by the sheer luck of reincarnated, Low-class trash?!" Riser clenches his fist as he becomes more angry by the second. "And the fact that this was this particular one's second time spilling it… with the first time being back when I first saw him… is starting to PISS RISER OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOFFFFFFFFFFFFFF!"
Everyone, minus Izuku winced when they heard Riser's blood-curling scream of rage.
'Oh no…' Ravel says in her thoughts. 'This is not going to end well.'
Riser points an angry finger at Izuku while glaring at him with eyes of fury, making the latter slightly widen his eyes.
"YOUR INSOLENCE HAS COST YOU YOUR LIFE, MIDORIYA! I'LL TURN YOU INTO ASHES, AND THERE'S NOTHING YOU, NOR YOUR PRECIOUS FRIENDS CAN DO TO STOP MEEEEEEEE!"
With a roar of anger, Riser sprouts his Phenex wings and takes flight above him.
"He's gonna what?!"
Rias became shocked at Riser's declaration. She, along with everyone, including Ravel, could not believe that he would go this far just to claim Rias as his bride.
'Dammit, Onii-sama,' Ravel says in her thoughts while glaring at Riser. 'If you kill him on purpose, you'll be disqualified, and you'll ruin your reputation!'
As soon as he got high enough in the sky, Riser's body becomes engulfed by his Phoenix flames, taking on the form of a large bird.
"Behold, Midoriya! This is the power of the Phenex family! The flames of the immortal bird burns within me! The Hellfire of my clan will SCORCH YOU TO DUST!"
Izuku kept his narrowed eyes on Riser while clenching his left fist.
"You think I'm scared of you, Riser?!" Izuku asks. "Sorry, but that fantasy of yours is shut down!"
Izuku then shifted his eyes towards his gauntlet.
'Ddraig, I think this is the appropriate time to use it, don't you think.'
{I agree. Just know you have much time than before...so don't waste it otherwise you will become fatigue due to how much stamina it takes. Also, while it will protect you from the flames of the Phoenix, the armor will get scratched up by them, so be careful, partner.}
All Izuku was nod his head in understanding while keeping his stare on Riser, who was laughing uncontrollably after Izuku told him that he wasn't scared.
"Even so, what do you hope to do?! Like I said before, you're nothing but Low-class trash who has mocked me for the last time!"
"Hmph! Simple, Riser! I'm going to use the power of a Dragon, YA BITCH!!"
Riser raises an eyebrow at him while staying quiet, allowing Izuku to continue.
"I've used my ten days wisely to be prepared for the likes of you, but unfortunately, I believe it won't be enough. That's why I've decided to do something back in the new school building in order to finish you off!"
Izuku unsheathes his Blade and places his Boosted Gear embedded arm in front of him with his palm facing towards him.
"I was aware of what would happen to me if I did this, but as long as it means I can save Rose, that's all that matters to me!"
Izuku proceeds to ball his left hand into a fist and punch upwards.
"Shine! Overboost!"
Upon saying those words, the gems on his Boosted Gear glow bright green.
{Welsh Dragon! Overbooster!}
After hearing Ddraig announce this, everyone, plus the three girls watching in the Student Council room, widen their eyes when they see parts of a red armor in the same shade as the Boosted Gear appear out of thin air and piece itself together onto his body. It started at the chest region, then to his arms, and now to his legs.
After those parts of the red armor formed, with a green gem in the middle of the chest plate, and one on each knee, arm, and elbow, the armor took on the shape and motif of a dragon, with a gauntlet on each hand, and boots looking like dragon legs and feet. On the back of the armor, there appeared to be a pair of what appeared to be jet thrusters for flying, and a dragon-like tail attached to the tailbone of the armor.
"This is the power of the Red Dragon Emperor!" Izuku announces as the helmet for the armor appears on his head. The helmet had two green eyepieces for Izuku to see through and two golden horns attached to the front mouth of the helmet.
"Balance Breaker! Boosted Gear: Scale Mail!"
"Balance Breaker?!" Rias wonders with a shocked expression.
"Amazing…" Ravel says as she stares at Issei's armor. "This is the Boosted Gear's Balance Breaker…"
"How did Izu obtain this form..?"
Rias jumps when she felt a tap on her shoulder. She turns her head to see Akeno looking at her with softened eyes.
"I think I can explain that, Rias."
~Flashback~
{So, you've decided on making a sacrifice?} Ddraig asks aloud for the Gremory Devils to hear. {You sure you want to do this?}
"Yes, I do," Izuku replies, earning gasps from Akeno, Kiba, and Koneko. "Are you in, or out."
{Like I said, I will grant you a power worthy of your sacrifice, if you do this, your left arm will permanently be that of a Dragon's. Can you handle that?}
Izuku nods his head in reply.
"Is there a way for me to transform the arm back in its human form?"
{Yes, there is. Because your arm will be that of a Dragon's, you're technically turning yourself into a Humanoid Dragon. However, it will take a very long time for you to take control of your arm's transformation.}
That was what Ddraig said but in reality...Izuku knew that what Ddraig was actually saying, "You're stronger than the transformation so you will be Alright"
After letting this information sink in, Izuku gives Ddraig another nod.
"Alright, let's get to it."
~Flashback end~
Rias and Asia were taken back by Akeno's explanation, with Rias being the most surprised.
"Izu did this for me?" Rias asks as her eyes soften at the armored Izuku, tears threatening to leave her eyes.
"Oh, Izuku-san…" Asia began while having a sad expression. "To think that you'd go this far…"
