Kais is an F- rank lvl 4 psychic who's only power is energy shield. Even though he has such a useful ability, he can't use it effectively because of his low PSY stat. After accidentally bumping in to an S-rank psychic during a guild meeting he was instantly marked for death, who would miss a weak person like him anyways. His own squad mates whom he had know for years left him to die in a PD ( a dungeon) after stealing his skill because they were paid to. Now just a normal human he fears for his life as extra dimensional abominations surround him. Thankfully his innate powers fully manifested. Now he will go from being a lowly F- rank psychic to the worlds strongest and kill the superior beings responsible for the destruction of old humanity.
