fami (chainsaw man)

Fami is a member of the Devil Hunter Club. She is later revealed to be the Famine Devil, embodying the fear of famine and hunger, as well as a member of the Four Horsemen. By extension, this makes her the big sister of Yoru.

In chapter 198, her true identity is revealed to be the Death Devil, who was using the real Famine Devil's name and identity as an alias.
