Thanatos, God of Death

Regulus of Leo, returned with tenfold power through training beyond human limits, engages Thanatos in the decisive battle to allow Tenma to advance. The Lion's ultimate technique — Lightning Plasma — is a cosmos explosion that defies divine law.

Regulus' sacrifice, ending his own life to imprison Thanatos in a cage of solar cosmos, is a spectacular death freely chosen. His father Lugonis, who doubted himself so long, can finally be proud. Tenma arrives within sight of the Lost Canvas and Alone for the final confrontation between the two best friends in the world.
