A few minutes earlier...

"You may have found your way into our lair, Hero, but will not let you stop our dastardly plans!" Iida declared, trying to channel his inner Villain for the role he was expected to play.

Mina, who had found the room with Iida guarding the fake bomb, grinned. "Hey, that's pretty good, Iida! Really getting into character there!" she complimented, not at all weirded out like some people might be, even giving Iida a thumbs up.

"Oh, uh, thanks, I just figured I should play the par- I mean, flattery will get you nowhere, pathetic Hero!" Iida replied, having initially been taken aback by Mina taking his acting in stride, but recovering quickly enough. "You shall not touch the weapon!"

"We'll see about that, evil-doer!" Mina exclaimed, shooting acid at Iida. He quickly dodged.

"You'll have to do better than that!" he shouted, before rushing her, aiming for a full body tackle. She quickly dodged to the side, putting slick acid right in his path as he did. "Ack!" he yelped as his superspeed caused him to slip, and go crashing right into several crates in a rather painful manner.

...

"...ouch," most of the students winced from the viewing room.

...

"Why you!" Iida bellowed as he got up, seeing Mina going for the weapon, sliding on her acid. "Crap!" he yelped, immediately going full speed, barely managing to reach and grab it in time, moving it away from her.

"Dang it, you're such a tease!" Mina remarked, skidding to a halt as she fired more acid after him, but he avoided it.

Iida choked a bit at the playful innuendo. "Do you think this is a game, Hero!?" he recollected himself.

"Not really, but I do play to win!" she shouted, continuing to shoot more acid around as Iida set the weapon down and avoided all of her shots.

"Your Quirk may be dangerous, but it will do no good if you can't hit me!" Iida declared, spending nearly two minutes dodging, before seeing Mina grin cockily.

"I don't need to~!" she replied cheerfully, before going for the weapon again like Iida wasn't there, and fast enough to stop her.

"You dare ignore me- what!?" he yelped, looking down, having been about to charge her at full speed, but realizing that was a bad move. The reason? All of her shots earlier were not her just frustratedly trying to hit him... Rather, she had covered the whole floor in streaks of relatively harmless, but very slick acids. Leaving nowhere for him to safely run with his Quirk without going on another slip and slide trip. "You sneaky little-!" Iida roared, thinking frantically.

In a **** bid to stop her, he decided to run forward anyway, aiming to use the resulting slip to carry him right into her. His aim was good, but unfortunately, so were Mina's reflexes. "Yipe!" she exclaimed, jumping over him as he skidded at her. "That was close, didn't actually think you'd try it anyway," she admitted, putting her hand on the weapon.

Immediately following was All Might's announcement of the Hero's victory, which stopped Izuku and Bakugo's fight midway, and Mina, being a good sport, went to help pull Iida out of the wrecked crates he had found himself in this time. "You okay?" she asked.

"...I'm going to be cursing your name in the morning when I wake up with the bruises, but yes," Iida groaned as he got up.

"Hey, don't look at me, you're the one who decided to try it anyway!" Mina laughed. "You'd also have to curse Midoriya's name, it was his idea to make the floor slick to use your own speed against you!"

"I see," Iida replied, unable to deny just how smart the idea was as they headed back to their teammates to head back to the viewing room and get their scores.
