Komiya Yuuta

He's an ordinary boy but raised was overprotected just a bit too much when raised. He is interested in sex (a little too much) as a boy of his age, but on the surface he seems serious.
He is not averse to learning, and is able to apply his knowledge easily once he has been taught the basics, and is rather clever.

He has a magnificent gem, as is typical of the protagonists of erotic games. He is capable of rapid-fire shooting, however, it seems that it's too much for a boy his age, and he is not able to handle it well.

His semen has aphrodisiacal effects, that'll make anyone do as he says.
