In the Tokyo district of Kinshicho, a reportedly haunted house becomes the unlikely home for three powerful characters from the Monster Strike universe: Neo, Solomon, and Lucifer. Rather than engaging in grand battles, the story follows their everyday, mundane lives as they coexist under one roof.

The manga is a slice-of-life comedy that places these typically heroic figures into ordinary, often humorous situations. Neo is a girl who cannot speak and struggles with expressing herself, often worrying that she comes across as too arrogant. Her daily interactions with her housemates, each possessing distinct and contrasting personalities, form the heart of the story's conflict and comedy. The supernatural elements of the source material are present but are woven into a domestic setting, creating scenarios that are sometimes magical but always grounded in the characters' personal dynamics.

The narrative primarily explores the challenges and warmth of an unconventional family unit. The final volume, the fifth, was released on January 8, 2026, concluding the series' publication run of approximately four years.
