Yohei Masuzaki (枅岢 葉平 Masuzaki Youhei) is one of the doctors who saves Kirito Kamui's life after he survives the Mount Kumataka plane crash during his childhood.
Masuzaki is a male of average height and build in his 50's. He has deep-set brown eyes with puffy underlids and blond combed back hair. He is typically seen wearing a white lab coat with gray piping over a brown-checkered collared shirt and brown pants.
He is a highly skilled surgeon, and a kind and caring person.
- In May 2099, Masuzaki is one of the doctors who transplant various parts of the 184 children who die in the Mount Kumataka plane crash into Kamui's damaged body. Eventually, he cannot stand being a doctor anymore which causes his crime coefficient to rise. To prevent being labeled a latent criminal, Masuzaki begins to take drugs and is later saved by Kamui, who manages to clear him.
They share a positive doctor-patient relationship.
