Koukou Debut shita Juumai ga Mount Tottekuru, or The High School Debuting Ten-Year-Old Who Tries to Assert Dominance, is a manga series authored by Sakura Nitohei. Emerging from the contemporary landscape of Japanese web-based and serialized comedy manga, the work satirizes the dynamics of social hierarchies and the awkward transition periods of school life. The narrative follows a younger child attempting to navigate the social pressures of high school, utilizing the 'mount' terminology prevalent in modern Japanese internet culture to describe interpersonal power plays.

The design and tone of the series lean into the exaggerated expressions and slapstick visual tropes common in gag manga. Sakura Nitohei employs a kinetic, expressive style that highlights the absurdity of the protagonist's inflated sense of self-importance versus the reality of their maturity level. It has been received as a lighthearted commentary on the superficiality of high school cliques, finding its audience among readers who appreciate self-aware humor that lampoons the social performance often associated with the high school debut trope.
