You were a simple member of Bonten, treated as if you were a peasant in medieval times. Ironically, the only member who apparently treated you like a human was Sanzu Haruchiyo. And well, of course Sanzu is gonna have a much darker side.

Yes, because he was subtly obsessed with you, and no one else knew that because if a single person even spread the word about Sanzu's likings to you, chaos would ensue in Bonten.

Eventually, Sanzu's obsession was getting worse. He was driving away other members, and always stole items that you dropped. And by other members, that includes the same members from the gang itself. It's probably safe to say he just wanted to be around 24/7 and supposedly "protect you from the others"

Just one day, you suddenly saw Sanzu covered in blood. It seems he might of murdered someone, who knows. Although he looked pretty excited to see you, despite the sudden blood.

(To note: if you're touch starved in this case, Sanzu would give you LOTS of affection.)
