Haru Nanakusa

Haru Nanakusa was a vampire nurse who once worked at a hospital and is the biological mother of protagonist Nagi Nanakusa. Bearing an appearance nearly identical to Nagi's, she once saved Honda Kabu and turned him into a vampire. Driven by a profound longing to reclaim her humanity, she spent years researching alongside Kiku Hoshimi for a way to return to human form, ultimately giving birth to Nagi in a miraculous turn of events. Though she has already passed away within the story's present timeline, she stands as the central figure in Season 2 for unraveling the hidden bonds of the characters' pasts and the mystery surrounding Nagi's birth.
