Tsuyu stared in horror as the villian - Shiragaki Tomura? - began to reach for Aizawa-sensei. Next to her, she sensed Midoriya shaking, with fear or anticipation, she wasn't sure. To think, only two hours ago, everyone was excited for the field trip to USJ and meeting Thirteen-sensei.

The attack had obviously been planned for quite a while, especially since Shiragaki continuously spoke about killing All Might-sensei. Looking around, she noticed the black mist (Kurogiri?) reappearing next to Shiragaki, while the disgusting monster continued to hold onto Aizawa-sensei.

Praying fervently, Tsuyu continued trying to think of a way to escape their precarious situation while maybe finding a way to help out their precious teacher.

Anger. Hate. Dark. Kill. Kill them all. Make them pay.

The longer he watched, the more violent his inner nature became.

How dare they hurt a youngling.

I will kill them all.

Feeling himself vibrating with anger, he took several long, deep breathes to try to calm himself. It would do no one any good if he lost control.

Tensing slightly when the...Toumu? Loumu? (Eh. Who cares.) smashed the youngling's face into the ground yet again. A dark growl began to emit from the green-headed boy.

"Midoriya! Come on. We should head towards the exit," whispered Asui. He nodded in agreement, despite the fact that his blood red eyes never left the youngling.

Switching his gaze from the youngling, Izuku watched the white-haired brat mutter, "...Actually, before that, why don't we use the opportunity to take..." With that, the brat suddenly appeared in front of the trio, hand grasping out, aiming for the frog-quirked girl.

Well, damn. While he had no doubt that had he not been exposed to so much sunlight in the past hours, he could have easily killed the brat where he stood, but he was also hiding his true nature, so it ended with him being unable to react fast enough.

Watching in silent anger as the brat reached out to touch Asui, he prepared himself to kill the boy immediately. Out of the corner of his eye, he noticed the youngling's head rising and he relaxed slightly, figuring out that he was erasing the brat's quirk.

"... You really are a cool guy, Eraserhead." The brat muttered, before the abomination once again slammed the youngling's head to the ground.

It was then that Izuku lost all control and set free his instincts, anger coursing through his undead veins.

KILL. KILL. KILL. KILL. KILL. KILL THEM FOR TOUCHING MY YOUNGLING.

Shiragaki Tomura watched with slight interest as the green haired boy began to shake. Was it from fear? He really didn't care, but what was very interesting was the dark aura radiating off the boy. In a matter of seconds, the black waves went from closely surrounding the boy to enormous shock waves that made the entire environment around them shake and rumble.

"We should leave, now!" He heard Kurogiri exclaim. Clicking his tongue in irritation, he ignored the other man in favor of watching the boy.

However, Shiragaki's second of distraction almost costed him his head.

Biting back a curse, he jumped back, barely avoiding having his head ripped off by the mysterious black claw-like that surrounded the boy.

"We need to go NOW!" Kurogiri yelled, attempting to wrangle a struggling and angry Shiragaki.

Kill them, whispered the bloodiest, angriest, and wildest parts of his brain.

Tilting his head slightly, he told Asui and Minata, "Get to the exit and find help. Hurry." Then, he faced the rest of the villains, all staring at him, slack-jawed. Chuckling, Izuku cracked his neck before facing those who hurt the youngling.

As Asui and Minata ran to the exit, Izuku sensed the presence of several other heroes getting closer to the USJ.

"Hmph. Since the other heroes are close, I'll just take you all out quickly," he muttered. Then he smirked. It wasn't a nice smirk, nor was it one that anyone ever thought would ever grace the face of Midoriya Izuku, a well-behaved, kind, and gentle student of UA. However, this wasn't Midoriya Izuku, UA student, but rather Izuku, a very old vampire with ancient roots.

"Kukukuku… YoU'rE All AbOUt tO HavE a vERy BaD TiMe~"

Toshinori wasn't sure what he expected when he and the other heroes stormed into USJ. Maybe lots of injured students, maybe villains everywhere, but under no circumstance did he think that he would find the scene that he did.

When he first entered, anger and guilt rushed through his veins as he looked at his now hopeful students. Almost immediately, he noticed that Midoriya wasn't with the group students.

"Where is Midoriya?" He asked the students, mind racing as he inspected each of the students, noting Thirteen's battered state and the absence of Aizawa.

"H-he's down there." One of the students told him. A sudden rush of worry filled him and after reassuring himself that the rest of the students were safe and were in the capable hands of the other heroes, he rushed to the center of USJ, hoping that he wasn't too late.

When he reached a cliff that lead to the center, he took in a deep breath, ready to proclaim his standard catchphrase, but paused when he took a close look at the scene.

It wasn't a scene he'd ever expect to see and he felt like a bit of his understanding of the world shatter a bit.

Standing at the center, surrounded by bodies of villains and covered in blood was one Midoriya Izuku, who was holding Aizawa closely, as if protecting the older man from an invisible enemy.

Shocked and gaping, he silently stared as Midoriya noticed the number one hero. Both looked each other in the eyes, one frozen in shock and the other blinking in quiet embarrassment. Both were silent as other heroes and students began to approach the scene to see what was wrong. Midoriya opened his mouth, despite rather softly uttering, his voice echoed in the eerily silent building.

"... Ah. Well, this is quite a predicament."
