Well enough, Yumi enjoys herself!

"So, let's get started!" Kirishima grinned, hardening himself. "Hit me as hard as you can!" he told Yumi.

"Bad idea!" Izuku hastily cut in. "What part of "can trade blows with All Might" did you forget?" he asked Kirishima, who paled.

"...right, good point..." Kirishima admitted, chuckling sheepishly. "My Quirk isn't that strong yet... Okay... maybe ten percent then?"

"That might still be a little much," Mina teased as Yumi smiled and drew her fist back.

"I can take it!" Kirishima grinned, bracing himself. WHAM! He yelped as he was sent flying back, and was embedded in the concrete wall of the training room. "...ow..." he whined.

"...too much?" Yumi asked Izuku, a bit concerned.

"...nah, he has a hard head. He wouldn't have learned otherwise," Mina giggled before Izuku could answer.

Yumi smiled and admitted, "Okay, good... that was actually pretty fun."

"...dang it, I'm stuck!" Kirishima shouted, struggling to get out of the him shaped hole in the wall.

"Just turn off your Quirk!" Kyoka shouted.

"...oh, right," he replied, shutting his Quirk off, his body shrinking slightly as he fell out of the wall. "...that's gonna hurt in the morning..."

Mina went next, deciding to practice her acid attacks with Yumi, who provided a moving target... a fast moving target. "Dang it, hold still!" Mina pouted as she fired another wave of acid, everyone else standing off to the side.

"That would defeat the purpose~!" Yumi taunted. She was clearly having the time of her life, enjoying the spar.

"...looks like she's becoming a combat junkie," Momo giggled.

"Yep," Izuku grinned, albeit a bit nervously. Yumi's personality was developing nicely, though he certainly hoped she wouldn't like fighting too much.

Mina eventually gave up, panting. "Well, dang," she remarked. "You're hard to hit for someone built for durability..."

"My original makers clearly wanted their bases covered," Yumi mused as she stretched. "Who's next?"
