|Appears In:||Yu-Gi-Oh! Soul Sound|
Kazehaya Otonashi is the protagonist of Yu-Gi-Oh! Soul Sound . He is newcomer to the game of Duel Monsters.
Kazehaya is above average height. He has slightly tan skin and is slightly muscular. He has tamed, white, single colored hair (as opposed to other Yu-Gi-Oh! protagonists, whose hair is usually multi-colored and extravagant). He has he has heterochromia, with his left eye being green and the other being red. Kazehaya usually wears a black, sleeveless shirt shirt with a cyan trim, black pants (with the same cyan trim as his shirt), a dark-red belt and black shoes. His always carries a pair of silver, over-ear headphones around, usually on his head, but when he's not wearing them, he usually places them around his neck or on a loop he has on his belt. He also wears a pair of dark-blue arm guards that go from his to below his elbow. When attending school, he wears the standard uniform but retains his headphones.
Unlike other Yu-Gi-Oh! protagonists, Kazehaya's name doesn't contain the syllable "Yu". His given name, "Kazehaya", translates to "wind" and "speed". His surname, "Otonashi", translates to "no sound", which contrasts for his habit of always having his headphones on.
Kazehaya is a complete anti-socialite. He keeps to himself, rarely speaks, and keeps interactions with other people to a bare minimum. He'll often use his headphones as an excuse to ignore people and as result, always has them on. Whenever interaction is required, he'll often only move one of the headphones off (usually his right ear) and will return it back to his ear when there is no longer a need for the interaction. He also seems to highly intelligent, scoring the highest on exams, earning the envy of his classmates as they deem him as someone who hardly tries. Beneath this exterior, Kazehaya is shown to be a generally good person. He will usually thoughtlessly (and notably, silently) help a person who seems to be in need and, without any thanks or recognition, will walk away. While he takes very little interest in most things, he seems to find Duel Monsters intriguing as when he participated in his first Duel, his usual stoic expression changed to that of an expression of child-like wonder and amazement.
