Meeting Mirko

With Izuku now intimately connected with his two lovers, the days had become even more pleasurable since they crossed that boundary. However, today was not one of those days. Instead, Izuku found himself on his way to Mirko's place.

As he made his way through a secluded forest reminiscent of his training grounds, Izuku couldn't help but wonder why she had asked to meet him there. While jumping from tree to tree, a sudden attack took him by surprise. Barely managing to dodge it, he looked back to see a woman standing where he had been. She had an athletic build with muscular arms and legs, stood slightly below average height, and had dark skin and red eyes.

What caught Izuku's attention, though, was her revealing outfit - a sleeveless white leotard that left little to the imagination. Her thighs were exposed, and the leotard did nothing to conceal her ample chest.

"I didn't expect you to dodge that. I wanted to teach you a lesson in area awareness, but it seems you've got that covered. My name is Rumi Usagiyama, and I want to fight you! Oh, and by the way... are you checking me out?" she asked.

Nodding in agreement, Izuku met her gaze and replied, "Yeah, you're quite attractive. As for your request, sure, let's fight!"

Mirko flashed a large toothy grin and launched herself towards Izuku, saying, "You're bold, huh? Let's see how long you'll last!"

…

3 Minutes later

…

Izuku lay on the ground, breathing heavily and wincing from the pain coursing through his body. Meanwhile, Mirko stood nearby, looking unamused.

Struggling to rise, Izuku conceded, "Okay... okay... you win."

This visibly angered Mirko, who kicked the ground and retorted, "You didn't use your quirk... That was boring."

"Hmm? I don't remember saying I'd use my quirk. I came here to be trained by a pro hero, not to entertain them," Izuku responded.

"Tsk, aren't you the strongest student in UA? What is there to teach you? I only called you here because you looked like you'd be a decent sparring partner," Mirko said.

Izuku smiled at her and got back on his feet, suggesting, "Alright, let's make a deal, shall we?"

"What kind of deal?" Mirko asked, curious.

With a mischievous grin, Izuku replied, "If you can bring me, without using my quirk, to a level where I can keep up with you in combat, then I'll spar with you all out. I'll summon my strongest abilities to give you a real challenge. Are you in?"

Mirko's smile widened, and she kicked Izuku away playfully, saying, "Hell yeah! Now get up, weakling. I'm going to make a badass out of you."

…

With bruises covering his body, Izuku sat down with Mirko as they both dug into their rice bowls. Mirko was the first to finish, and she looked thoughtfully at Izuku before sharing, "You're pretty resilient. When my old master trained me for the first time, I was knocked out for a full day."

It was true. Mirko had spent the last four hours pushing Izuku to his limits, making him carry giant logs on his back while dodging her full-force attacks. She had also taught him some basic martial arts by having him practice on trees, going all out.

Izuku grinned at Mirko and playfully joked, "Maybe it's because you're too weak to knock me out."

In response, Mirko delivered a punch strong enough to knock him out for a couple of hours, saying angrily, "Poor choice of words."

…

Izuku dedicated his days with Mirko to train and strengthen his true self. He understood that his powers might fail him someday, and in this world, there were various methods to temporarily seal or steal abilities. So, he needed to be prepared for any situation.

"Damn," he groaned, stepping back as another kick came his way. Trying to dodge, he ducked, but Mirko's left fist still landed on his face.

"Stay focused. Every time your mind wanders, your entire body becomes predictable and weak," she lectured.

Amidst the training, Izuku's phone buzzed, indicating a call. He glanced at the screen and saw it was Momo.

"Hey, what's up, Momo," he greeted, momentarily ignoring Mirko's instructions.

Curious, Mirko asked, "Who's that? AND ARE YOU IGNORING ME?"

"Oh, sorry, just my girlfriend. We have a date tonight. I'll call Mina, too, to remind her. See you soon. Love you," Izuku replied.

Mirko's expression deadpanned as she muttered, "He's not even eighteen yet, and he has a girlfriend. Ugh."

Curious about his mood, Izuku asked, "Why are you looking a bit down, Mirko? What's wrong?"

Snapping back to the training, Mirko said, "Never mind that. Was that your girlfriend?"

"Yeah, her name is Momo. She's pretty cool," Izuku explained.

Mirko nodded and advised, "Well, don't let your teenage love distract you from training. By the way, who's this Mina girl? Why does she need a reminder about your date?"

"Oh, Mina is my girlfriend too. She's cool as well. We're going on a double date. Or should I call it a triple date? Nah, that doesn't work. I'm going on a date with both of them," Izuku casually revealed.

Gobsmacked, Mirko exclaimed, "Forget the analogy! You have two girlfriends!!!??"

"Yeah," Izuku replied nonchalantly, as if it were an ordinary thing.

...

Izuku's training days were progressing well. Meanwhile, the Hero Killer Stain was becoming more active, catching the attention of the League of Villains, who sought to recruit him for their cause.
