The Salvation Organization That Started as the Riddler

Rean was summoned from death and told that the world would be destroyed in three years. "I stand on the ruins of civilization and say this to you. From now on, everything is up to you~" After being assigned the main mission by his irresponsible self in parallel time and space, what greeted him was: The exotic swordswoman who never speaks through her brain; the late-stage chuunibyou who thinks she is the protagonist of a shounen comic and rushes to her with "Wow!"; The second-generation kid who is obviously weird but always believes that he is the real savior; the super-rich second generation who has an explosive personality but can't offend because of the organization's funds... Many years later, Rean, known as the person responsible for the fate of mankind, the first shield of civilization, the leader of the savior, the ineffable succubus, and the prophet with only half a mouth... Will always think of the afternoon when he first decided to save the world. "Oh, I didn't know this task was so simple at that time~"
