"Ucchare Goshogawara" centers on the life of Goshogawara Tsurugi, a high school student with an extraordinary ability to attract chaos and misfortune. Despite his best efforts to live a normal life, Tsurugi's presence often leads to bizarre and unpredictable situations, earning him the nickname "Ucchare" (meaning "eccentric" or "weirdo"). The series explores his daily struggles as he navigates school, friendships, and family dynamics while inadvertently causing mayhem wherever he goes.

Tsurugi's family plays a significant role in the story. His father, Goshogawara Ryuunosuke, is a flamboyant and over-the-top individual who runs a struggling ramen shop.

Together, they form a dysfunctional yet endearing household that serves as the backdrop for much of the series' humor and drama.

At school, Tsurugi interacts with a colorful cast of characters, including his best friend, Kurosaki, who often finds himself dragged into Tsurugi's misadventures. Other classmates, such as the serious and studious Aoi and the mischievous twins, Riku and Rina, contribute to the chaotic atmosphere. The series balances slice-of-life moments with over-the-top comedic scenarios, often involving misunderstandings, exaggerated reactions, and surreal events that defy logic.

The narrative structure of "Ucchare Goshogawara" is episodic, with each episode presenting a self-contained story that builds on the characters' relationships and quirks. Themes of family, friendship, and self-acceptance are woven throughout the series, as Tsurugi gradually learns to embrace his unique identity and the chaos that comes with it.
