Shachiku-chan to Seikatsu Kaizen-kei Shota Akuma

Hanabishi Inori is a talented office lady who is overwhelmed with work. One night after work, she eventually reaches her limit. She opens a book she bought in Jimbocho to summon demons and wishes for her company to burn down. Then, a small demon with the appearance of a shota (young boy) appears before her! Inori, who has been busy with work and neglecting her private life, begins a strange life of cohabitation with the slightly absent-minded but devoted and cute demon.
