At first, I was confused because I couldn't figure you out. I was on guard because a kid I couldn't read came up to me smiling. Though I soon let my guard down. After I found out you were a Child of the Kishin, I distanced myself. Because we'd eventually have a sad parting. Because Oni have short lifespans. But it didn't work. Your eyes looking at me when I suddenly distanced myself were so vivid, and that face with the fading smile got stuck in my head. Damn it, I'll stay by your side, so don't make that face. . . . ...But what am I supposed to do if you leave first?

I can't forget that moment. You were hesitating more than usual that day, and then you said with a slightly awkward smile, 'They say I'm a Child of the Kishin.' I know, of course I know. Child of the Kishin. Overwhelmingly strong, but with a short lifespan. From that day on, I developed a conviction. That I wouldn't let anyone around me die. Don't worry! I... I'll definitely save you. . . . ...I lived thinking that way... Why... why didn't you wait for me? You idiot.

I brushed it off coolly, but I couldn't sleep in my room that night. A kid who smiles so warmly. Dying once the mark appears in adulthood. I'll protect you until the end before that happens. Well, if it gets annoying, I won't. . . . Hey, where exactly are you looking that's different from us? Don't just smile, you bastard. Once we're back from this mission, it's a week of rest.
