Komiyan III is the in-game character of Komiyama, a fourteen-year-old junior high school student who attends the same school as the twin protagonists Shugo and Rena. His avatar is designed to look like a snooty nobleman: it wears oversized armor, a large frilly scarf around its neck, and has a bulbous sneering face, often topped with a pair of goggles. He is almost always seen riding a grunty named Oscar, which he treats as his trusted mount. In personality, Komiyan III is pompous, proud, and self-absorbed, even calling himself the King of Aloofness. He has a distinctive laugh that quickly gives him away offline. Despite his grand airs, he frequently ends up in unintentionally comedic situations because he fails to read social cues. His main motivation is a persistent crush on Rena; he constantly tries to win her attention and affection, though she shows no interest in him. He first appears during a Tanabata event in the game, where he heckles Shugo but soon recognizes the twins as his real‑life classmates. From that point he becomes a recurring comic‑relief character, often trying to insert himself into their adventures in a bid to impress Rena. Offline, Komiyama is simply a classmate who shares the same school environment as Shugo and Rena. His interactions with the twins are mostly one‑sided, as his advances toward Rena are ignored or rebuffed, and he occasionally butts heads with Shugo. Komiyan III does not undergo significant character development; he remains a boastful but harmless side figure throughout the series. His most notable traits are his attachment to Oscar, his unmistakable laugh, and his inability to take a hint, which together provide light‑hearted moments in the story. His abilities as a player are not highlighted; he serves more as a source of comic contrast to the main cast than as a skilled combatant.
