The two fight sequences here justify the entire OVA's existence, each one meticulously choreographed down to the smallest counter and breath. If you've stuck with this franchise through its messy timeline, this is the payoff that reminds you why you cared in the first place. The ecchi doesn't interrupt the action, it breathes with it, the same way the best entries in this genre always have.
Picking up right after Ikkitousen: Xtreme Xecutor, the Nanyo Academy students travel to Kyoto on a class trip, and so do other schools from the Kanto region, including Seito High. The visit turns out to have a purpose: gathering tsuba to boost their spiritual power and physical strength. Old rivalries between the Kanto schools soon flare up, and Kyoto's own fighters arrive in force to challenge the visitors. Between a bus race, bodiless Reikon and the local toushi, the historic city takes a beating in this action-heavy ecchi OVA.
