"No matter how much you change, Takane, I'll always like you."
A character from the Kagerou Project. He appears in the second novel.
Basically, he is the previous incarnation of Konoha.
He is Enomoto Takane's only classmate in the special needs class. He has a mole under his right eye. He has gentle mannerisms and goes at his own pace. He talks like an airhead, and Takane usually winds up being his tsukkomi. He is good at and likes drawing pictures, and his skill level is fairly high.
He suffers from a "serious disease" that will kill him if he ever has another attack. Perhaps because of this, he is very self-contained despite his airy personality, and is not good at asserting himself. Concerning making a project for the school festival, he says "I'm very weak, so if I collapse all of a sudden I'll just cause trouble, and looking at everyone else it seems like preparing takes a lot of effort, so I don't know if we can do it..." and Takane has to motivate him out of his negativity.
Also, ever since the school festival, Takane gets him hooked on a certain online game, and he even creates his own custom avatar.
Even though he is frail, he is a big eater, and is apparently the type who will never get fat no matter how much he eats.
Haruka himself appears to be too dense to notice it, but Takane actually likes him.
Past (Spoiler Warning)
He dies from an attack of his disease.
At that time, he is drawn into "Kagerou Daze." He is possessed by the "Me wo Samasu (目を醒ます)" snake, and obtains the ability to recreate his body as an idealized form.
