Retired Boss Shelter Center

The protagonist, rated as the most useless person in history by the "Union of Superpowers", is actually the only hidden S-class in the world who can "copy the powers of others". He was arranged by his missing father to join a real estate company that specializes in retired S-class bosses. The task is to coax this group of old monsters who have the ability to destroy the world but just want to dance in peace to "voluntarily resign and enjoy their old age."
