Kuroha looked with surprise at the one who opened the door for him. Mirko, the hero ranked fifth. A very powerful woman. Kuroha wasn’t a fanboy like Izuku and Nighteye, as such his knowledge of heroes was rather sparse, but it was hard to not know her since Minagata had a larger poster of her in her Hero costume in his room.

Right now, she wasn’t wearing her hero costume, but rather a pair of tights jean and a beautiful grey shirt. 

“Oh! So you’re one of my juniors Master talked about? Enter.”

She opened the door wide and stepped aside. Kuroha didn’t mind her and did as he was told. Anyway, he didn’t have too much luggage on him. The interior of the room was rather large and luxurious. It was clear that Mirko didn’t lack money. What more if his suspicions were right, the totality of this building belonged to her. This was rather astonishing

Kuroha looked around a little before finally settling down and took a seat on one of the chairs and stayed silent. He didn’t really care about what she would do. As long as she gives him shelter and something to eat he would be happy. In the worst case, he would simply be at Himiko's home. Her might not be as large as Momo, but it was still large enough to be called a mansion.

Meanwhile, Mirko was looking at him with contemplation. Milienia wasn’t someone anyone could take as a master. If it was a game, she would be the equivalent of the super powerful old master full of mysteries who trained the hero and transformed him into a super fighter with some weird and painful, very very painful training regiment. In fact, from what she knew, Milienia trained a very large amount of heroes throughout the world, and many of them reached a rather high level.  

But, even then, all of them were nothing more than playing in Milienia's eyes. Well, a plaything was a little derogatory. At most they could be called pass time that she enjoyed for a while before becoming bored. Only a very select few of those she trained could call her master. The criterion wasn’t strength, nor talent, but rather simply liking. If she liked them she would take them as a disciple. If she didn’t, she would just teach them some little things before going away and redo everything.

Mirko was one of the select few. She wasn’t Japanese from birth, but rather from a war-torn country in another part of the world. There, it was a dog eat dog type of world. In that country, she already stood out as a powerful figure and was revered by many. But, once she met her, she was crushed so mercilessly that she had a nightmare for the following week. Worst, after Knocking her out, Milienia actually kidnapped her before sending through the world as a mercenary and then telling her to go to Japan.

That was why she didn’t form a team and agency. She didn’t know why her master wanted her to play the hero in Japan, but she knew that it wouldn’t be pretty. What more, in her eyes heroes who join teams were nothing more than cowards. One should only rely on his or her own strength to go through any adversities.

Anyway, she really wondered what Master saw in him. After all, even though the two of them were disciples. Mirko could feel that the love master had for this boy was far greater than anything else. When she talked to her about him and how amazing he was, she felt like her master was taking Kuroha as her own child or something even closer.

Looking at the boy in front of her, the first thought that flashed through her mind was how alike they were. The same red eyes, the same tanned skin, the same long white hair. Apart from her rabbit ears, anyone who saw them would think that they were related in some way or another.  Well, of course, that was impossible. She might be an orphan, but she knew who her parents were. Just that they were killed during the war. Still, she would be lying if she said that his appearance didn’t make her feel closer to him.

This wasn’t all. She could see it, this kid was different. His mind was different. When he saw her, apart from a mild surprise, he showed no other emotion. Few kids could be as calm and as bold as this one. For her, more than their matching appearance, and the fact that they had the same master, seeing him so calm was what pleased her the most. She hated how wishy-washy most heroes in Japan were. she nodded to herself

(If he is half as amazing as the master said, then he being here won’t be boring.)

She was about to open her mouth and speak to him when one of her phones rang. She had two phones, and this one was exclusively used for work. She frowned a little before temporarily ignoring it.

“Look, kid, I need to go. I wrote my number on the fridge and left a magnetic card for you to enter the building.  This entire apartment building belongs to me. The first and second floors are reserved. So search for a room on this floor. Any room you like. It will be yours later. When I come back tonight, we will discuss it more thoroughly and I will give you the magnetic card for the room you will choose. Are we clear?”

Kuroha looked at her for a short while before simply nodding,

“Yes.”

Mirko simply went to change, and roughly ten minutes later, left the house, with Kuroha alone in it. 

----

Kuroha now alone, didn’t directly go search for a room. He didn’t particularly care about it. After all, it’s not like he would sleep in it, and since apart from reading and training he had no other hobby, he didn’t need something fancy. 

Right now, what he needed to do was to reassess his situation. He needed to see things from a higher and broader perspective. He also needed to plan his future as a vigilante and if he would ever wear the Crimson Devil armor. 

All those were decisions he needed to plan for carefully, sadly he had no one to confine to. At the same time, he remembered how he missed his previous meeting with Ferrum Femina. But, well, she should understand that he couldn’t appear right now. What's more, with his current identity, he didn’t think that she would still want to team up with him.

Finally, he sighed before taking his phone. Yesterday, he received a message from Momo asking him to come to meet her today. He didn’t want to just teleport to her like he did with Himiko. It would be pretty awkward to suddenly appear in front of her parents or something like that. He dialed her number,

“Hello, Momo are you free right now? Yes? Ok, then I will reach you soon.”

After hanging up, he vanished and went toward Momo's position.

Meanwhile, the situation in the conference room was rather heavy. Last time, the conference was full of screams and bravado, this time it was so calm it was eery. Right now, only the top ten heroes, as well as the executives of UA and shiketsu were present.

After deep and relentless analysis, it becomes clear how they were unable to receive any information about the attack and were still in the dark. The same as to how the mastermind could grasp such an accurate timing when they were. Only two answers were possible...Either they were very incompetent, or, and most likely, there was a traitor in their midst.

(AN: OK. For you to understand how OP Mirko is. You must think back to the Nomu. Nomu are classified and the black Nomu all might fought in USJ was a high level one.
Mirko Destroyed three of them in just a few minutes and before that she exterminated a group of low levels nomu(The one who attacked during the stain arc). Basically you can say that Mirko is equal in power and most likely stronger than the weakened All Might.)
