Half-human

A half-human (半人間, ...) is a human-ghoul hybrid. They are specimens with mixed blood from a ghoul and a human.

Origin
Half-human individuals are stated to hail from the Sunlit Garden, where they are bred for the purpose of hybridization.

Characteristics
Individuals are labeled as "half-humans" because they are neither a ghoul or a human. They cannot manifest kagune or a kakugan, and can consume normal food. Their special attributes are highly developed physical capabilities and a shortened life span.

Even when heavily injured by being pierced through the abdomen, Hairu Ihei kept on fighting, albeit in a chaotic state.

Half-ghoul cases such as Eto Yoshimura are very rare, and most of the "failed" experiments are classified as "half-humans"

Kishou Arima claimed that the reason for the impairment in his vision is due to an illness called glaucoma, which is a well known illness among the aged and elderly.

The only known way of giving birth to a half-human is through special breeding conducted at the Sunlit Garden.
