Imouto Loveru

Sakura Yamato, a reclusive genius, prefers the company of his collection of little sister figurines to human interaction. He lives alone, keeping only a stuffed rabbit, a remnant of his deceased older sister, as a conversation partner. One day, the rabbit suddenly speaks, declaring its affection for him is unmatched. It then transforms into a woman with rabbit ears and identifies herself as his sister, sent from Heaven to grant him one wish from God.
