OVA
Description
Seishirō Inumine studies at Ayanagi Academy's Musical Department as part of Team Hiragi. He stands 185 cm tall with short green hair and bright orange eyes. His school uniform is typically worn casually: an unbuttoned blazer, loose tie, untucked shirt, and often missing the standard vest. Training attire consists of a white zip hoodie with black trims, an orange shirt, grey shorts, and white dancing shoes.

His personality bursts with dog-like energy and unfiltered spontaneity. He frequently breaks into song, actively seeks food, and exhibits tunnel vision when focused. While described as useless outside musical performances, he possesses natural talent in music and physical activities. Academically, he struggles profoundly, failing midterms and makeup tests repeatedly, though his artistic strengths led teachers to overlook this. Weaknesses include allergies to clay, poor cooking skills, and difficulty with technology and machinery. Conversely, he excels at rock-paper-scissors and physical education.

His family runs the Chinese restaurant Bow-Wow House in Yokohama's Chinatown, where he acts as the mascot "Shumai Dog" for events. He adores meat, tapioca drinks, and prefers running over cycling due to ignorance of traffic rules. His daily rhythm revolves around singing, eating, and sleeping, which also serve as his stress relief. He habitually grinds his teeth and sleeps with his eyes open.

Within Team Hiragi, Inumine shares a close, though taxing for roommate Akira Ugawa, dynamic. Izumi Toraishi often manages his antics using commands or thrown shoes, directing him like a dog while Shu Kuga watches sympathetically. His interactions extend to other teams; notably, he and Yuta Hoshitani accidentally broke a priceless vase at the Hiragi villa during Season 1, resulting in a distinctive hole patched with mismatched wood in the pantry wall. He nostalgically recalled this incident alongside Nayuki Toru in the Halloween OVA, collectively apologizing for the damage.

His musical performances include the duet "Sparkling Sparkle ☆" with Ugawa and the ensemble piece "Gift ~Curtain Call~." Alternate franchise scenarios feature him: as the Shumai Dog in the "AYANAGI Animal Park Series," a chef at Ryokan Hiragian in the "AYANAGI April Fools Series," and a prisoner in the "AYANAGI IF Series" postcard set.

Across all media, Inumine's core remains consistent: his musical prowess and physical robustness starkly contrast his academic and practical ineptitude. He endures as Team Hiragi's mood maker through seasons and OVAs, fueled by an unwavering passion for singing and performance despite recurring comedic mishaps.
