Mimasaka, Ryou

美作涼

Ryō Mimasaka, known as "Gorgon Shell" (石化の盾, lit. "petrifying shield"), employs "Oshiroibori" (白粉彫り) tattoos that are nearly invisible to the naked eye to hypnotize opponents, slowing their metabolism to the point of paralysis. She is very close to Sano Yasuyoshi, having known him since their school days, and works under him. She sacrifices herself to save Sano from being killed by Nike.
