Good Luck! Ninomiya-kun - S01

Shungo Ninomiya is an average high school student living with his older sister Ryoko, when she's not off working as a mercenary. His quiet life takes a sharp turn when Mayu Tsukimura, a shy girl, lands in his schoolyard in a military helicopter. She and her older brother Mikihiro have been sent by Ryoko to stay with them-but there's a catch. Mayu is a succubus, and Mikihiro is an incubus. To make matters worse, Mayu suffers from androphobia-a fear of men-and Ryoko insists Shungo help her overcome it. Her methods are… unconventional, forcing Mayu and Shungo into uncomfortably close situations, like sharing a bed or bathing together. Things only get messier when Reika Houjou, the student council president, becomes their new maid and vows to sabotage their awkward training. With these bizarre new housemates, Shungo's once-normal life spirals into chaos.
