Ясухіса Нашіро

Nashiro Yasuhisa is an artificial one-eyed ghoul who impeded Ken Kaneki's pursuit of Madam A alongside her twin sister Kurona.

She was fatally wounded in battle, and abandoned to die by Akihiro Kanou. Her sister claimed that she survived on as a parasitic mass on her stomach, but Kanou claimed this to have been nothing but a delusion to cope with Nashiro's death.
