Recca declares that he's Yanagi's personal ninja in front of the entire school, which causes all kinds of rumors. Fuko, Recca's rival, decides to see whether there's any truth to the claims.

Recca finds a kindred spirit in the new history teacher, who knows all about the ninja of the past. The visit to the teacher's home, however, goes wrong when enemies show up to kidnap Yanagi.

In order to unlock the secret of immortality for his father, Kurei has kidnapped Yanagi. Recca sets off to rescue her, with Domon and Fuko joining him to settle their own scores.

Unable to accept his team's "easy" win, Recca challenges the leader of Team Kuu, Kukai, to a final showdown to determine everything. But Kukai's not the saint he's described as.
