Tokumitsu Shintaro is a typical high school boy living alone in a modest apartment when he encounters Towa, a gentle and pure-hearted girl who appears on his balcony one day, claiming to be an angel sent to learn about humans. Despite his initial skepticism, Shintaro lets her stay, and their sweet, innocent cohabitation begins. As they navigate daily life, their bond deepens, but the arrival of other quirky characters—like a snow spirit classmate and a vampire with a flair for drama—adds chaos and charm to their routine.

Beelzebub, a ditzy yet powerful demon lord who adores all things fluffy, rules the bureaucratic underworld of Pandemonium, where she’s served by Mullin, a serious and pure-hearted attendant who idolizes her strength but is flustered by her quirky habits. Surrounded by a colorful cast of demons—like the silent, teddy bear-loving Azazel and the nervous Belphegor—Mullin strives to keep Beelzebub on task while grappling with his growing feelings for her. Set in a whimsical hell filled with oddball characters, this charming tale blends comedy, romance, and lighthearted antics, following a demon lord and her loyal aide as they navigate work, love, and the fluffy chaos of their daily lives.
