Seiren's Links
very concerned about why he chooses to continue killing as a profession, knows he doesn't tell her everything about his emotions, curious about his past (which is seemingly dark).
loves how she's a great listener, wants to tell her details of past but afraid to endanger her, often forgets how capable she is of fighting on her own, overly protective of her. he also tries to help Seiren fix bikes... but he has no clue what he's doing and usually fails.
