Ichika, "Sin"'s Links
< Itsuo's younger sister. >
"My older brother? If you ask how I feel about him... Well, he's a retired superhero to me! Kidding, I don't think he's saved anyone. Rather, perhaps he needs some saving of his own. Eh? You're asking if that's the reason I became a vigilante? Ahaha... What a creative imagination you have there."

“Sin? You mean… Ichika? What? People actually call her by that name? …Don’t tell anyone we’re related, okay? Oh, just being recognized as a chuunibyou’s relative… That sends chills down my spine. Wait, how did you find out in the first place? Did she... tell you? I'll have to observe you to see if you're worthy of her trust.”
