Kongouji-san wa Mendou Kusai

Kongouji-san wa Mendou Kusai, known in English as Kongouji-san is Troublesome, was written and illustrated by mangaka Toyoda Minoru. The series began serialization in Kodansha's seinen magazine Monthly Afternoon in 2017. Toyoda crafted the narrative as a quirky, philosophical romantic comedy that centers on the titular character, a high-achieving and somewhat intense girl who navigates life with an overwhelming, almost aggressive sense of sincerity and earnestness.

The series is celebrated for Toyoda's distinctive, energetic art style and his ability to weave deep thematic questions about human nature and society into the framework of a school-life manga. Critics and readers frequently noted the work for its unconventional pacing and the protagonist's unique, often exhausting personality, which subverts standard romantic comedy tropes. It concluded in 2019, leaving behind a reputation as a highly regarded, cult-status title within the seinen demographic.
