Last time, Katsu was fighting off a few people from his past. Hironori knows about the swords those twins wield.
So what do you mean? I asked. Who are you talking about? I asked. Well, you girls need to go to the origin of your power and those swords. Hironori replied. I don't know where my words come from. Ally replied. So you guys have to go train in the wilderness? Aoi asked. We have already unlocked our abilities years ago. Aoi replied. Oh, kiss my ass. I replied. You might have unlocked yours through rigorous training. "They" forced you three to learn how to use your weapons. Hironori replied. I know all about the hell I endured. Katsu replied. Seriously, you underwent training. You make it seem like it was pure hell. Ally replied. Yeah, Higanbana was heavy as hell, and her power was so overwhelming. I ended up nearly dying because of all the blood I lost in training. Katsu replied. You almost killed him, Higanbana. Ally asked. His powers hadn't fully developed, so I helped him develop them. Higanbana replied. So you are the reason he came home with bandages all the time? Rin asked. You can say what you like. Higanbana replied. After all, they made him use her to test his skills by killing people. After that, you cloaked him in your darkness. Hironori replied. I did it to protect him. Higanbana replied. After all, he doesn't even have black hair or brown eyes. His eyes and hair color are mmmm. Hironori replied. Katsu covered his mouth. You talk a little too much. Katsu replied. You know you can't erase your hair and eye color. Hell, I'd kill to have your hair and eye color, Katsu. Rin replied. I literally wish we could. Katsu replied. I thought you had black hair and brown eyes. I replied. Well, since I am French, Italian, and Japanese, I'm the only child who took my mom's hair and eye traits. Katsu replied. Wait, you are bi-racial? Ally asked. Now that I look at you, you really don't look fully Japanese. I replied. To be honest, I never thought they would mix you with different races like that. Aoi replied. Well, our dad loved foreign women; he didn't want to date or marry a woman of his race. He wanted to break the cultural barrier, so he did. Katsu replied. Well, we really need to tell Yukimoto about those five. I replied. I already know about them. After all, the leader of that whole bunch was no other than Katsu himself. Yukimoto replied.
