Power: Life Coagulation
A young man who's heart was hardened after [Hinagiku](https://anilist.co/character/319954/Hinagiku-Kayo)'s kidnapping. His Guard is [Itecho](https://anilist.co/character/319957/Itechou-Kangetsu), 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.
