I am looking for a manga where the main character gets summoned to another world with some people and gets the class 'god', which lets him be able to do anything. Then he gets summoned again along with some people by the demon lord and get a class 'demon lord' or something, which gives him the power to manipulate reality.
Summoned to a parallel fantasy world many times
It might be "めっちゃ召喚された件" (in romaji "Metcha Shoukan Sareta Ken THE COMIC"), translated as "Summoned to a parallel fantasy world many times".
First volume cover
Guy's whole class gets summoned to another world, except he's the only who one was transferred to a different one. Just when he gets used to his new life, he gets summoned to another world again, and again.
