A Kagerou Project character.
Appearance and outfit
He has short black hair that may extend between eyes, black eyes with bright pupils, and a mole under eye. In the anime, his school uniform consists of a white collared shirt, a green cardigan, and a black-blue plaid pants.
He is what Konoha used to be. A friendly and sickly boy with a weak heart, Haruka was friends with Enomoto Takane and attended the same classes as her. He later befriends Tateyama Ayano and Kisaragi Shintarou (with Haruka confiding him about his terminal illness). He suffers a fatal heart attack in class while Enomoto wasn't paying attention, and in the Heat Haze world wishes for a stronger body. He gets this at the cost of becoming Konoha, losing his emotions and pain receptors in the process.
