Kokage-Kun Wa Majo

Kokage-Kun Wa Majo summary: Yumeko, a high school student, resides in a dilapidated housing complex with her family, where the population is sparse. Oftentimes lost in reverie, she seeks the help of Kokage-kun, the complex manager and a solitary hikikomori residing on the rooftop, who wields magical powers as a witch. Yumeko is inclined to selfishly request Kokage-kun's assistance using his supernatural abilities, such as when she attracts the attention of a charming senior schoolmate who invites her on a date.
