There are those who still roam the world aimlessly trying to survive with every last breath, though well hidden in their demeanor, Ringo and Ohji fit this description but even people such as them have something to hope and believe in. Meanwhile their are those who believe in something completley different, and also search for Luna for opposite reasons, these are bandits of Dio's army who search to live and conquer the world. Even with this army by his side, Dio believes that he can only become all powerful by defeating Casshern himself.

Dio's conquest is once again interrupted by the news of an attack on his army, while searching for Luna is serveants were attacked, much to Dio's surpised. Followed by Leda, Dio searches for the assailants as a way to learn more about Luna.

She leaves Dio, leaving him alone to remorese his defeat until he is interrupted by the arrival of his former commander, Braiking Boss. The tyrant reminds Dio that his rage is pointless and his obsession with Casshern has made him vulnerable to facing his own kind.

Braiking Boss finishes by telling the fallen warrior that the reason he is considered weaker then Casshern is because of Casshern's former lack of emotion as a pure killing machine, but now he and the two assailants both have goals, instead of obsessions. Dio is inspired by Braiking Boss' words to prove that he will achieve his ultimate "goal" of defeating Casshern and sets off to reclaim Leda.

Dio successfully learns from the error of his ways and gains strength from his true ambitions. Just as Casshern and his group do, once they stumble apon the former home of the Sun..Luna.
