Atsumu Miya

Atsumu Miya is an second year highschool student who lives in Hyogo Prefecture, Japan.

Outwardly, Atsumu appears to be a carefree, confident person who's usually seen with a lazy smile on his face, though he enjoys provoking people and giving offhand compliments. He can be quite condescending, and somewhat selfish at times. His twin brother, Osamu Miya, describes him as someone who doesn't listen to others, doesn't return what he borrows, and lies habitually. He also appears to be a perfectionist who has ridiculously high standards for himself and his spikes. Atsumu is a competitive person who hates losing; sometimes, these traits can veer off in a bad direction.

As of 2018, he is a member of MSBY Black Jackals, a professional volleyball team in Division 1 of Japan's V. League. He is also a member of the Japan National Volleyball Team and participated in the 2021 Olympics.
