Genya is an ill-tempered, arrogant, stubborn, and caring individual who doesn't possess a breathing style to slay Demons, instead he does it the old-fashioned way. Genya is the younger brother of Sanemi Shinazugawa, the Wind Hashira. Genya is known to have a caring attitude at some times, being overprotective of his loved ones and making sure they're safe and will get mad if they aren't. Although he's tough and mean and bitter to others, he is secretly sweet and has a sweet heart.
