The Sunlit Garden (白日庭, Hakubitei), also sometimes referred to as the Garden (庭, Niwa), is a facility owned by the Commission of Counter Ghoul. It is responsible for providing "talented" children with a special education, though it is not publicly disclosed what this means. The organizations V and the Washuu Clan are also involved in the Garden's management.
The facility has not been shown, leaving many mysteries concerning its appearance or location. Flashbacks of the facility feature a field of flowers, though it is unknown whether this is literal or symbolic.
The children of the facility wear a simple uniform, consisting of a white high-collared shirt and black slacks. Other children, such as Rize and Furuta, are shown wearing white hospital robes.
The Sunlit Garden is a facility that breeds and raises half-human children, training them to become talented Ghoul Investigators upon their graduation or to join V. It also houses "bred" Ghouls such as Rize Kamishiro, used to preserve the pure-blooded Washuu bloodline.
