Little Sister Darkness is the third installment of the prank, touching, and sleep rape simulation game.

Recently, my sister became seriously ill. She claims to have a demonic eye, and her actions are completely incomprehensible.
Yes, this can’t be easily cured… it’s Chuunibyou.
She still looks down on you, people say she’s disgusting, and you always make fun of her.

Tonight, show your “true power” and become the demon king of the night!
