Kai is a kind-hearted and agreeable guy. He gets along with mostly everyone, and can make anyone laugh. To many people (and girls) he seems like the perfect guy. He can carry a conversation anywhere and has good hobbies that make a lot of friends. Kai is interested in playing sports, with his favorites being basketball and running track. He likes to pass time playing handheld games that he keeps in his backpack. Though he can always be listening to CD's on vintage devides like a CD player because he's convinced that the quality is better. Kai loves self-care and is always taking care of himself, whether it be his hair or his skin. Though his favorite hobby is painting because it calms him and takes his mind away from things.
Kai is an average sized male with a slender build. He gains muscle the longer he's working as a hero. Kai has an oval face and slanted sea green eyes. One of his notable features is his long and wavy hair. He can be seen with it tied up, but more often than not it's pushed back.
Kai was born in Kauai, Hawaii. His parents were very loving. Though when Kai turned ten, his parents were victim to a villain attack, leaving Kai alone with his younger brother. Kai decides to become a hero, so that he can be a person that his younger brother can depend on and be someone that he can look up to. While they lived with relatives, Kai had to fend for the both of them, and they eventually relocate to Japan during middle school for an opportunity to join a prestigious hero course. Kai works odd jobs in between his transition to Shiketsu, but ultimately prepares for his future as a hero.
