Rosei Kantsubaki

Occupation: Agent of Winter
Power: Life Coagulation

A young man who's heart was hardened after Hinagiku's kidnapping. His Guard is Itecho, a trusted older brother figure of his since childhood. He is known to be rash with his powers, using them to protect others rather than to solely bring Winter.

Rosei begins a relationship with Hinagiku after reuniting with her. Out of consideration for Hinagiku's assertion that she is different from her old self, he begins to call her 'Hina', a nickname she only allows Rosei to use.
