Kumagawa turned to face Tomura, and for once his ever present smile was nowhere to be seen. In its place was a look of utter loathing. [You seem to misunderstand something.] the teen said as he ripped a screw free from the skull of a dead Villain, blood and brain matter dripping from its point. "When you come at someone with lethal intent, you convey the following message; I want to kill you. I want to kill you enough that I am giving up all moral protections that have shielded me, and I am prepared for that, if you are superior in battle, you kill me. When you attack someone with the intent to kill it means that you are putting your life in the hands of two people, yours and your enemy's. So it's only natural that I respond in kind."
Aizawa along with Midoriya, Asui, and Mineta were utterly terrified by Kumagawa's sudden shift in personality. To think that the ever smiling boy would so easily resort to killing.
[Besides, it's much easier to manage a dead body than a live prisoner.] he finished as his smile returned.
"... You can't be real." muttered Tomura. "No way in hell should someone like you be a Hero. So why are you on their side?"
[It's quite simple really.] Kumagawa said as he juggled the screw in his hands. [I just want to win. That's all. And the Hero's always win in the end. That's just how a Shonen Jump works.]
"..."
"Tomura-san, I think it would be best if we make our escape now." advised Kurogiri.
Tomura looked over to Noumu who was almost free from its bindings as it struggled to rip its arms off. "Looks like we've run out of arcade tokens. No more replays for now. Let's g-"
A loud explosion shook the facility as the front doors flew inward with great force.
"HAVE NO FEAR!" came the booming voice of a familiar Hero. "FOR I HAVE ARRIVED!"
"ALL MIGHT!" cried the students.
"Ahh, and just like that, we get an extra life." remarked Tomura.
"I had a bad feeling in the pit of my stomach, so I cut the principals long story short and rushed over here to check on you all. I happened upon young Iida on my way here and thanks to him, I heard the gist of what transpired." All Might explained as he ripped off his tie. "It's alright now. FOR I AM HERE!"
"We were waiting for you Hero. Or should I say, Hero trash." spoke Tomura. "Change of plans Kurogiri. The Final Boss has appeared at last. Looks like our raid hasn't failed~."
"Tomura-san..."
"You and I will take care of mister unhinged over there." he instructed as he pointed at Kumagawa. "Noumu, I'm leaving All Might to you."
The beast let out a roar as it finally broke free and began to regenerate.
