No one P.O.V

Y/N and Enji looked at the three Nomus surrounding them: the Winged Nomu, the Black Nomu and the Horned Nomu were slowly getting closer to the two Todorokis, bringing them back to back. The Black and the Winged charged at Endeavor and Ragnarok, Y/N didn't waste any time, put himself between his father and the creature and did the Zai kuji-in. His left eye glowed a bright red light while his flames bursted out of him and drastically increased the temperature. His flames turned a bright and beautiful shade of blue and purple, the concrete around him started melting and Y/N gathered his flames on the tip of his right index finger.

"Kagutsuchi: Gehenna Blast!" Ragnarok said, his fingertip touched the Nomu, the light shortly disappeared before a first shockwave blew everyone away, except Endeavor who was watching with great awe his son. Barely a second later, another stronger and hot shockwave spread again, this time even making the Flame Hero fall on his butt, while a bright and extremely hot explosion engulfed the Nomu and blasted in away on a great distance, turning the creature into a sort of shooting star soaring the night sky at great speed. "Hm, better."

Witnessing the dangerous flames, the Winged Nomu chose to step back, grabbed a defeated Pro Hero and flew away with them in its claws.

"Ragnaro-" Endeavor started, Y/N snapped his fingers and reinforced his father's fire, cutting him off and the older Todoroki smiled before pursuing the flying Villain. Enji threw a first fireball at it but the Nomu evaded it with a quick turn. The Flame Hero melted his feet into a building in order to scale it and once he was high enough, he jumped off the building to reach for the defeated Hero but failed to catch them. Endeavor then gathered his flames into a spear and threw it through the Nomu's eye, forcing it to drop the Pro Hero. Enji caught his colleague, landed safely using his fire and but the Pro Hero down while he looked at the fleeing Winged Nomu. "Ragnarok. I'm chasing this one. You go get the Horned one. The others who can stand up and fight, go to the district four." He said, Y/N nodded and immediately left. He ran into the streets, looking for both the Black Nomu and the Horned one.

Ragnarok looked around, felt a fire burning near so he walked to that place and found the Black Nomu's corpse being completely calcined and still burning.

"I don't know if Sakuyan will be able to examine it in this state... I still need to adjust the output while using the Zai." Y/N sighed, poked the Nomu and it turned to ashes making him grimace. "Welp, still have another one." He said to himself and continued to look around. A few minutes later, he heard people screaming and running away from a building. He ran into the said place, saw it was an university and texted Sakuya to tell her he would need help to evacuate people or make sure no one was hurt and sent her his location.

The boy quickly ran into the university and asked the few students that he saw what happened, to which one answered that a monster had barged in one of the amphitheaters at the back. Y/N asked them to wait outside in a safe place while he would take care of it. He checked a first amphitheater then a second and found nothing. He then walked to the third place as he got closer, he heard muffled yet panicked noises so he broke open the door and saw the Horned Nomu slowly walking to a group of students then one of them recognized him.

"Y/N!" Natsuo shouted and Ragnarok shook his head side to side.

"I'm working for my internship at the moment so call me Ragnarok, thank you." He sternly said and looked at the Nomu, who had turned around and was growling at him. "Helios." He uttered, the flames composing his long coat intensified then reshaped into the fire lion, whose roar increased the temperature. The Horned Nomu didn't even have the time to move as Helios pounced on it and gruesomely chewed it like a mere toy, making all the students expect one gulp.

"Wow..." Natsuo trailed off as he looked at his younger half-brother taking care of the Villain effortlessly. Helios walked back to Y/N and sat in front of him, slightly wagging its tail.
