Dosetsu is a handsome and well-built man with magenta hair, blue eyes and oval-shaped glasses. He is mostly seen wearing a shirt and a coat along with dark blue jeans.
Dosetsu was born with a bead in his palm. When he was younger, he and Mutsuki Inuyama (also known as Hamaji) were separated. Before that, he promised her to come back and find her eventually. He was given her hair pin. During one night, he was dying in the snowstorm, but a snow spirit named Yukihime appeared before him and asked why does he want to live. He told her about his little sister and stated that he wants to live to be by her side, in which Yukihime granted his wish and saved his life but she sacrificed her own voice for that reason.
Mutsuki/Hamaji's older brother is Dosetsu's younger sister who cares a lot for her.
Yukihime is the snow spirit who saved Dosetsu from death at the cost of her voice and always accompanies him making everywhere around him cold, even during summer.
- "I have a little sister. We were separated when we were younger, but she's still my only sister. «I'll definitely come get you». That's what I promised... But I was never able to fulfill it. So... I have to live... To be by her side." (to Yukihime)
- The reason for Dosetsu's unusual hair color is because he is from the family of physicians. It was customary for them to begin developing an immunity to various drugs starting at an early age and their Magenta hair is the result of it.
- The reasons of Dosetsu and Shino Inuzuka to live was for Hamaji's sake as they both wanted to be there for her.
