Otohana Sumire

Otohana Sumire is a student at Millennium Science School and the head of its Gym Training Department. Standing at 167 cm, her hobbies include gardening and working out. Sumire is an athletic girl with a deep passion for physical training, and she strongly believes that all problems can be solved through muscles and exercise. She takes training very seriously, even referring to Sensei as her "Trainer." Sumire hopes that more people will develop an interest in sports as much as she has.

Sumire has long black hair that reaches her legs, tied into a ponytail with a purple scrunchie, and her eyes are a striking purple. Her halo is a violet, bulky, dashed pentagon with a hollowed five-petal flower inside a circle. Her outfit consists of a shiny white jacket with black lines, a flower-patterned sports bra, black stretchy pants, purple slings with a matching purple belt, and silver sneakers with purple shoelaces and green soles. She also wears a violet flower hairpin on her right bangs, a green belted choker, a green armband, a clover necklace, and an orange visor hanging on her sports bra.

Sumire wields a two-tone Benelli M1014 semi-automatic shotgun with a purple forearm, stock, and pistol grip. The receiver and barrel are painted white. The shotgun is outfitted with a custom handguard attached to the lower grip and receiver. The Millennium insignia is imprinted just beside the ejection port, and the words "Back Home" are inscribed above the grip, though this is not the shotgun's nickname. Instead, Sumire refers to it as the "Latest Millennium-made Dumbbell," carrying it around while exercising. She also occasionally equips herself with training sandbags, designed to be wrapped around the arms and legs, which are surprisingly heavy due to the iron powder they contain.
