Chūshaku Kometani, a student at Itan Private High School, serves as a narrative observer and commentator. His name, combining kanji for "loyalty" and "explanation," homophonically mirrors "comment," reflecting his role. Physically, he sports short black hair with three distinct tufts and a featureless face that underscores his deadpan demeanor, though rare flashes of a bright, transformative smile reveal unexpectedly youthful charm. Positioned often at scene peripheries, Kometani dissects events through dry, fourth-wall-breaking remarks delivered in square narration bubbles—rounded only during his infrequent smiles. He navigates friendships with Shisuto Naruse, Hitohito Tadano, and Makoto Katai, mediating their dynamics while deciphering slang from figures like Manbagi Rumiko. His perceptiveness bridges character motivations and audience understanding. Heir to a temple priesthood, Kometani balances familial expectations with academic mediocrity, prioritizing minimal effort over high achievement. Despite self-assessed average athleticism, he excels in snowboarding and dominates the fictional game *Great Struggle Numabukuro Brothers*. His two sisters, both romantically involved, remain tangential to his explored relationships. Blending snarky bluntness with quietly considerate gestures, Kometani critiques Naruse’s antics yet advocates for his virtues, nudges Tadano toward empathy, and safeguards peers’ secrets. This pragmatic loyalty earns trust from figures like library head Ringo Hayashimi, who tolerates his silent narration in study spaces. Initially peripheral, Kometani gradually integrates into Tadano’s circle, securing a place on Komi Shouko’s friend list by their second year’s end. He vocalizes preferences for "reliable" individuals and casual observations on physical traits but deflects romantic speculation. Across official narratives, he remains a stabilizing anchor, clarifying plot threads without direct entanglement. Subtle growth emerges through increased social participation and fleeting emotional candor, epitomized by his disarming smile—a stark contrast to his trademark stoicism.
