Hinagiku Kayou

Occupation: Agent of Spring Power: Life Stimulation

Hinagiku went missing for around ten years, taking the season of spring with her.

[She's been in love with [Rosei)(https://anilist.co/character/319955/Rosei-Kantsubaki) since childhood.]

She later reunites with Rosei and enters a relationship with him. Because she sees herself as a different person from before her kidnapping, Rosei begins calling her 'Hina'—a nickname only he is allowed to use.
