Sakura Oshigiri

As a compassionate and soft-spoken member of The Underground Comrade, this young woman is Zakuro's devoted younger sister. Though her selfless nature leads her to wander off to help others, she carries deep guilt over past mistakes involving her brother. After being sent to the White Room following a gaming mishap, she formed a vital bond with Chihiro. Together with Nanami, they survived years in hiding until Kaikoku eventually discovered their secret underground sanctuary.
