Kotetsu Miyasaka is a kendo prodigy. While his twin brother, Yayoi, practices the sport, though, he lacks his sibling's skill, enrolling in a different school to try and differentiate himself. When things go wrong at Yayoi's new school, though, Kotetsu finds himself caught up in a potentially life-or-death confrontation -- only to suddenly find himself swept back to Edo period Japan where the stakes are infinitely higher!Taking in by Souzou Sagara and his roshi band of samurai, Kotetsu must find a way to survive in the past and possibly help shape Japan's future!
Kotetsu and the rest of the Satsuma roshi band set out to protect the life of Lord Sakamoto who has been targeted for assassination. Turns out, though, that this isn't the easiest guy to defend! Can Sagara and his men stand against the bloodthirsty Shinsengumi and carve out a more just future for Japan...?
Sakamoto has been successfully scooped off the streets of Kyoto to the safety of the Satsuma mansion once again. But even under constant guard, the Hero of Japan--and his amorous inclinations--cannot be contained! Despite the dangers, Sakamoto ventures out again, heedless of the mounting threat against him--or the trouble he's making for his guard, Kotetsu!
Despite his hopeful ideals for the future of the empire, Sagara remains troubled by his past. With Kotetsu's support, the two visit the home of one of Sagara's former students, Seitarou, hoping to learn what became of him and what may be driving the vengeful Shikyou Kawase to pursue the roshi band. It turns out both Sagara and Kotetsu have a history with Seitarou Miyasaka! Meanwhile, the Satsuma clan takes advantage of Sagara's absence to launch a violent assault, undermining all of the roshi captain's careful diplomatic plans. When the flames are extinguished and the ash settles, the Sagara's fire seems to go out with it. Perhaps through Kotetsu, Sagara can glimpse the future Japan and regain his hopeful outlook, even as his own path darkens...
