"I must say, red fire as dark as yours has been quite rare to see. Most fire users generate orange fire, do they not? If I remember correctly, red stars are the colder of their kind too."

Izuku shook his hands and extinguished the flames that had coated them. "Yeah, I remember that from our science classes. And yeah, they can be a bit colder than like the fire our stove puts out. You'd think it's magma for such a maroon color, right?"

The vine-haired girl nodded and her quirk wrapped around in front of her body. "Even then, your flames can still cut through my vines like a knife through butter. I was hoping your temperature would give me a fighting chance."

Izuku looked around the open field and track on their school grounds, tallying each pile of ash and charred hair that piled all over. A short sparring match to test endurance and mobility never hurt anybody, especially when the two in said combat could regrow their hair and/or skin.

"It's not like fighting you is a breeze, Shiozaki. If I didn't have my fire, I don't think any normal blade would be able to cut through your hair. And besides" - Izuku held up his hands and shook them about - "I can only light my hands on fire and I don't have the same flexibility in my shoulders that you do with your vines."

That was a blatant lie. Izuku could ignite his whole body on fire if he so wanted to. The fire wasn't even a quirk. His mother was born with the ability to pull objects towards herself, but she had rarely trained it beyond lifting objects over 15 pounds. The king of Hell doesn't have quirks; he has power. Izuku's ability to burst into a silhouette of flame and burn away his skin to reveal the demonic form his dad gifted him for his thirteenth birthday was one of his holy powers, not a quirk. It had been a bit hard to hide that from a teacher with the ability to erase quirks, he'd admit.

And Izuku didn't hate the red fire his father had bestowed upon him at birth. Sure it wasn't to the intensity of orange or blue flames - fire was still fire and a burn was still a burn - but given it's the maroon flames that dance across the fields of the Underworld that sears visions of horrors and torments into the souls bound to the floor of Hell as easily as it sears their bodies physically, Izuku was happy he had what he had. And he got to control whether or not he forced nightmares into his classmate's consciences during sparring, so using fire at all wasn't a risk for him. He could get away with it.

"I wouldn't sell yourself short, Midoriya." Ibara plopped herself on the ground beside the green-haired teen, her vines twirling around as a makeshift chair beneath her. "Your quirk may be limited to close range only, but you've proven yourself to have the guts to charge in with little hesitation. I would say it's an admirable trait for a hero to have."

"Thank you." Izuku smiled back and bowed his head. He probably shouldn't tell her about the chains he can shoot from his wrists. It'd be a bit awkward now. "I'm happy you have the kind-hearted side of heroism. You'll be an amazing one."

Ibara's returning smile surpasses his own as she stood back on her feet. "Shall we spar another round? We still have some time before dinner." Her vines snaked around the dirt as they traveled behind her and rose into a striking pose. It reminded Izuku of Nagini back home, just a brighter shade of green than the one-hundred-headed serpent. He would have to remember that for later.

Lucifer's son rubbed his hands together until smoke was forming from his palms. He liked her smile. "Yeah, I'm down. Best three out of five?"
