I Reincarnated as an Alien Monster. Re:Alien

Kikuchi Yukiko, died at age 24 because of brain cancer. When he reached Heaven, "God" told him about the reincarnation cycle and told him to live a new life in another world. He just went along the flow and accepted, just before he was told that his reincarnation body would be set as random. Hoping not to be a lowly worm in the next world, he spun the Wheel of Life and ended up chosen as a [Monster].
