[Redemption: Rebirth at the End of the World]-A story of redemption from the pursuit of the two great forces of darkness and light. 7. " Doomsday's Ultimate Enhancement "-The story of the protagonist strengthening himself during the outbreak of the apocalypse. 8. " Doomsday: Infinite Evolution "-The protagonist returned to three minutes before the end of the world and sought a breakthrough in the evolution of mutated creatures. 9.
