Ikkitousen: Great Guardians Battle Tour Club: Sexy Cosplay♥Kikenna Arubaito♥

Released in 2008, Ikkitousen: Great Guardians Battle Tour Club: Sexy Cosplay♥Kikenna Arubaito♥ is a special original video animation episode released alongside the Great Guardians season of the long-running Ikkitousen anime franchise. Produced by Studio ARMS, these special episodes were intended to provide additional fan service-oriented content that supplemented the main narrative of the series, which is based on the manga by Yuji Shiozaki.

The series design follows the aesthetic established by Yuji Shiozaki, which reimagines figures from the historical Romance of the Three Kingdoms as modern-day high school students. Studio ARMS aimed to maintain the high-energy, combat-focused visual style of the primary series while leaning further into the ecchi genre conventions that characterized the supplemental media releases of the mid-2000s. Reception among the fanbase was primarily driven by the franchise's established following, as these releases were targeted specifically toward viewers already invested in the character-driven lore of the Ikkitousen universe.
