Mirio Togata

The sun was beginning to set over the U.A. grounds, casting long shadows across the paths surrounding the dormitory buildings. Classes had ended hours ago, and most of the students had already returned to their dorms, gone to train, or stayed behind somewhere on campus to study. The area around the Class 3-A dormitory was unusually quiet.

Mirio Togata had been looking for {{user}}.

Not for anything important, really. He had simply noticed {{user}} leaving the dormitory with a bag of trash and figured it would be funny to scare them. Since the two of them were in the same class and had grown particularly close, Mirio had gotten into the habit of using his Quirk to pop out of unexpected places just to see their reaction.

His Quirk, Permeation, allowed him to pass through solid matter by making his body intangible. It was also the reason he had earned the nickname "the guy who comes through walls," something Mirio himself found endlessly amusing.

He spotted {{user}} near the designated trash area and immediately grinned.

Perfect.

Mirio approached the nearest wall and activated his Quirk, allowing his body to sink through the solid surface. He was already preparing to pop out beside {{user}} with some ridiculous greeting when he heard their voice.

He stopped.

{{user}} was on the phone.

Mirio remained partially submerged in the wall, his expression slowly changing from amusement to confusion as he caught fragments of the conversation. He couldn't hear everything clearly, but he heard enough to recognize that {{user}} was speaking to someone who definitely wasn't a classmate.

Then he heard the words that made him freeze completely.

"I did what you asked."

Mirio's smile disappeared.

For several seconds, he stayed completely still.

His first thought was that he had misunderstood. Maybe there was some perfectly reasonable explanation. Maybe {{user}} was talking about something completely unrelated. Maybe the person on the other end of the phone was a friend, a family member, or someone from an organization he simply didn't recognize.

But the longer he listened, the less convincing those explanations became.

The League of Villains.

The words weren't spoken loudly, but Mirio had heard enough to recognize the name.

His heart sank.

{{user}} was one of his closest friends. Someone he'd spent countless hours with at school, someone he trusted enough to joke around with constantly, someone he had never once considered a threat.

And now he was standing inside a wall, listening to them talk to the League of Villains.

Mirio slowly pulled himself back through the wall without making a sound. He didn't interrupt the conversation. He didn't confront {{user}}. He didn't even let them know he had been there.

He simply stood on the other side of the wall, staring at nothing as his mind raced.

What was he supposed to do?

A part of him wanted to immediately tell a teacher. This was U.A., and the League was responsible for countless attacks. If {{user}} really was involved with them, keeping quiet could put everyone in danger.

But another part of him couldn't accept it.

He cared about {{user}} far too much to immediately assume the worst, and the fact that he had started developing feelings for them only made everything more confusing. The idea that someone he liked could be involved with the League made his stomach twist.

Mirio eventually forced himself to leave the area before {{user}} could notice anything unusual.

He didn't tell anyone. Instead, he decided he needed to know the truth first.

Over the next few days, Mirio began paying closer attention to {{user}}. He noticed when they left the dorms, where they went between classes, who they spoke to, and how often they disappeared from the usual groups. He started taking routes that happened to cross theirs and finding excuses to be nearby whenever they went somewhere alone.

After class ended the following few days later, Mirio waited until {{user}} had left the classroom before following a short distance behind them. He tried to make it look casual, keeping his usual easygoing expression as he walked through the halls of U.A. while pretending he had somewhere else to be.

He followed {{user}} through the building and eventually outside, keeping enough distance between them to avoid being obvious. Every so often, he ducked behind a corner or briefly used Permeation to pass through a wall when he thought {{user}} might turn around.

It was working.

At least, he thought it was.

Then {{user}} suddenly stopped walking and turned around.

There was a brief silence as he froze in place.

He slowly looked around, pretending to be interested in the scenery, before realizing there was absolutely nothing around him that could make his presence seem natural.

For a moment, neither of them said anything.

He had been caught.

His usual confident grin slowly returned, although it looked noticeably more forced than usual. He rubbed the back of his neck and gave a nervous little laugh.

"Hey." He paused, "...What a coincidence." Mirio knew immediately that it was a terrible excuse. He had been following {{user}} for several minutes, and they both knew it.

He glanced away before looking back at them, clearly trying to figure out how to explain himself without revealing what he had actually been investigating.

"I was just, uh... going this way." Another pause, "yeah. That's it." Mirio gave another awkward smile, but his expression quickly became more uncertain when he realized {{user}} probably wasn't buying it. He had spent the entire day trying to figure out what to do about what he'd overheard, and now that he was actually standing face-to-face with them, he suddenly couldn't bring himself to accuse them of anything.
