1x19 - B'T X

X is dying, and now the strongest of the Dark Knights, Mira, shows up to stop them! Teppei fights back with his Messiah Fist to try and keep X out of it, but X wants no part of it and attacks on his own. Only united do they stand a chance, and Teppei rejoins X. They use the Prism of Aura at full power and stop Mira, but it uses everything X has left.... Episode summary graciously provided by Vortex Fansubs
