One Eyed Ghoul

A one-eyed ghoul (隻眼の喰種, sekigan no gūru) is a human-ghoul hybrid who possesses a ghoul's abilities. Most ghouls treat their existence as an urban legend or have never heard of their existence at all

Characteristics
One-eyed ghouls earn their name from the single kakugan they possess, in contrast to normal ghouls. In all other ways, they appear to have no obvious differences from an ordinary ghoul. Some individuals are noted to have a unique scent that combines traits of a human and a ghoul, identifying them as different and often considered "enticing" by certain ghouls.

There are 3 types of Half-Ghouls/One-eyed Ghouls in game.

1- Floppy

2- Natural Half Ghoul

3- Artficial Ghouls
