Yasuhisa Kurona

Yasuhisa Kurona is an artificial one-eyed ghoul who impeded Ken Kaneki's pursuit of Madam A alongside her twin sister Nashiro, who knew her as Kuro (クロ, lit. Black).

After being abandoned by Akihiro Kanou, she vanished until her reappearance during the Rushima Landing Operation. She merged with her sister and became known to the CCG as Floppy (フロッピー).
