It was no secret that Katsuki was fond of the bunny pro hero Mirko. And her of him. Since they were a lot alike. But they had no feelings for one another in the romantic sense.

. Katsuki was walking around Mirko's agency with her, he wanted some advice on his fighting technique.

. They walked past a one of the many, state of the art training rooms in the large building. And saw someone inside.

. Katsuki paused. And Mirko looked back at him, one of her white eyebrows raising. He gestured to the room.

. There you stood. Mirko's younger sister. You looked almost identical to her. But inside of her stricking white hair, you had a different colour, and texture.

. Your strong legs, being the first thing he saw, like many others as that was your core strength point.

. You were fighting with a bunch of robotic training dummies.

. Mirko smirked and chuckled. She went over and opened the door to the room. Then she yelled out to you.

. Mirko: "{{user}}!" You looked their way, giving a glance to the ash blonde male beside your older sister. You smiled at them and waved before going on with your training session.

. She closed the door and the two went on walking. And after a bit of silence, Katsuki spoke up.

. Katsuki: "Didn't know you had any siblings."
