Hi☆sCoool! SeHa Girl: Dai-54-Kai Hanpa Jano! Zenryoku de Guu! Youshou Suru no wa Only You! Subete no Gakkou Gyouji o Kako ni Suru! SeHaGaga Gakuen Taiikusai

Released in 2016, this OVA episode serves as a supplemental entry to the Hi☆sCoool! SeHa Girls project, a collaborative multimedia initiative between Sega and ASCII Media Works. The franchise was conceived as an anthropomorphic reimagining of Sega's iconic hardware—specifically the Dreamcast, Sega Saturn, and Mega Drive—portrayed as students attending a specialized school. The series blends high-energy slapstick comedy with meta-commentary on gaming history, aiming to honor the legacy of Sega's consoles while introducing them to a modern anime audience through vibrant, 3D cel-shaded animation.

The production sought to capture the chaotic energy of the original series while leaning into the absurdity of school-themed tropes, with this specific episode focusing on an over-the-top athletic festival. Designed by the creative team at TMS Entertainment and Sega, the visual style prioritizes expressive character models and rhythmic humor. Upon release, the episode was received primarily by the franchise's established niche following, serving as a nostalgic celebration for long-term Sega enthusiasts who appreciated the deep-cut references to gaming peripherals and classic titles.
