No, there's a method to the madness!

"...screw it, I'm going in," Bakugo finally said, and Izuku blinked, before he nodded. That did seem like the best way to get to the bottom of this. "And she better have a damn good explanation for dragging me out here," he added.

"Right, let's go," Izuku agreed. He and Bakugo approached the door, and knocked on it. It swung inward, the latch too deteriorated to keep the door closed against any degree of pressure. That raised no confidence. "...okay, seeing as it's open," Izuku said cautiously as they stepped in.

They saw no one in the first room, even when they looked around. They took a few steps in... before they heard a slam behind them and whipped around. "What the!?" Bakugo demanded as they stared right at Mirko, who had slammed the door hard enough to wedge it shut, partially splintering some rotting wood.

"Tsk, tsk, you both already failed the first test," she remarked. "You completely failed to notice where I was waiting. I wasn't even really hiding. Then again, basic fact about most people... few people ever look up."

Izuku's eyes widened as he looked at the ceiling right above the door. There were some holes in it straight up to the upper floor, not large enough for her to fith through, but certainly servicable handholds. She must have dropped down stealthily behind them once they had passed beneath her. Note to self, develop the habit of looking up in the future.

Bakugo also kicked himself for not thinking of that, but didn't show it. "...and why exactly did you bring us to this dump?" he demanded.

Mirko smirked, and got into a stance. "You see, I borrowed this place from some developers who are going to tear it down tommorrow for our first meeting. Because... you both are about to show me what you've got firsthand... and I didn't want to risk breaking anything nice..."

Bakugo paused, before he grinned. "...okay, that actually makes sense," he replied, cracking his knuckles. Izuku gulped and readied himself as well. He and Bakugo were about to spar against the Number 6 Hero... surely they could handle this, right? She wouldn't go all out, after all. What pro would?

One look into Mirko's eyes, and seeing the eager bloodlust in them made him immediately reassess that line of thought. "...this is gonna suck," Izuku mentally wept.
