Shirosaki Reito was suddenly sucked in by a mysterious crack and got transferred in between dimensions. He got reincarnated as a baby in another world. He was born in the royal family and was the heir to the throne but he was driven/kicked out of the palace. The reason was that he was born as a Support magician and had "Alchemist" as a job, which was the lowest job that existed in the new world, and people who had that were considered jobless. Luckily for him, there was a secret hidden in that job!!
