In the fictional town of Mahoro on the outskirts of Tokyo is Tada Benriken, a small business which does odd jobs. Its owner is the solemn and level-headed Tada Keisuke, and his unexpected guest, the easygoing but vague Gyoten Haruhiko, a former junior high school classmate who showed up one day and started to sponge on him. The two of them get on like oil and water, and yet are somehow inseparable. They receive queer, dubious incoming odd job requests which they accept, and what comes into view are the friendship between them as well as the backgrounds of their clients.
