UPDATE (Jan 27, 2025): I've finally created some Ice Breathing forms! They're still in it's early stages, but it's basically what I've been envisioning for him. I'll get around to creating a reference for the breathing form separate from Fuyuki's character page for people who need it ^^

A demon slayer with a cold face and a warm heart. Ever since he passed his Final Selection, Fuyuki has spent many years trying to pinpoint the whereabouts of the demon that had took his family. All the while pushing away people that cared about him and wallowing in his grief. Fuyuki is still learning to let people back into his life and live without the sorrow controlling it.
