Moshi Ano Ko ga Tracen Gakuen ni Itte Nakattara. Spe Senpai no Baai

This work originates from the expansive fan-created media culture surrounding the 'Uma Musume: Pretty Derby' franchise. It serves as an alternative history narrative, exploring the hypothetical trajectory of the character Special Week had she not enrolled at the central Tracen Academy. Such works are common within the doujinshi community, where creators expand upon the established lore of the multimedia project, which was launched by Cygames to personify historic racehorses as young women.

The volume is illustrated by the artist known as Saboten_Mushi. The design and artistic direction focus on maintaining the familiar visual identity of the 'Uma Musume' characters while shifting the tone toward a specific 'what-if' scenario. These independent publications are typically distributed at specialized events like Comiket, where they are received by the fanbase as supplemental character studies that provide depth to the personalities originated by the core development team.
