Tokyo Ghoul Manga Dub
Moldy Man for Nishiki Nishio
Nishiki is a diligent student and prodigy. He has an insensitive attitude with a knack for abrasive language. He also demands that people younger than him show respect for their elders. He joins Anteiku so that he is provided with food and doesn't have to kill humans to eat. After the time skip, Nishiki is primarily noted as a ghoul hunting other ghouls, showing little regard for the lives of both humans and ghouls alike. He is ruthless in dispatching those he considers troublesome or useless, killing those unfortunate enough to encounter him.

(Moments after Nishiki had just cleanly kicked a ghoul's head off in front of Kaneki)
"Didn't I just see you at the convenience store? Oh... you're a ghoul. Guess I didn't have to be so nice. I would've eaten you if you were human."
(Nishiki mentally spares with Kaneki, wondering if it was only a matter of time before he decided to eat Hide)
"The moment you betray an idiot who believes in you and when their anguished expression emerges the looks of hopelessness and such from other humans, just doesn't stimulate ones' appetite the same way right?"
(Nishiki begins panicking whilst being stabbed repeatedly by Kaneki's kagune)
"Stop it! Stop it you fucking idiot! I'm dying, I'm dying! I'm dying! I'm dying! I'm dying! I'm dying! I'm dying! I'm dying! I'm dying!"
