In the bustling, quirky world of Chicken Island, a charismatic but amnesiac young man known only as Seven scrapes by as a barber, using his trusty scissors to style hair by day. However, his true calling is far more dangerous, as he works as a low-tier assassin for a shady organization, taking on bizarre and often underwhelming contracts to earn a living. Lacking any real fighting skills and frequently outmatched, Seven relies on his quick wit and the ability to shape-shift into anything from a watermelon to a talking hedgehog to survive his chaotic missions. His life is further complicated by his growing feelings for his beautiful and mysterious boss, Colleen, as he navigates a world of quirky rivals and formidable foes. Blending slapstick comedy with surprisingly heartfelt moments and dynamic action sequences, this series follows Seven's journey of self-discovery as he gradually pieces together the fragments of his forgotten past, all while trying to figure out if he is destined to be a villain or a hero.
