Kiss kara Hajimaru Isekai Harem: Ipputasai no Sekai ni Tensei Shita node Kami ga Kimeta Unmei no Hito wo Sagashimasu

Takuma Kuze lost his life in a freak accident on Christmas Day. However, he was reincarnated, in his original form, by the god of another world, Alvaresia. The mission that God gave him was not to defeat the demon king or rebuild the new world, but to find himself a wife in Alvaresia, where polygamy is allowed! (Source: Takeshobo, translated)
