キスからはじまる異世界ハーレム　～一夫多妻の世界に転生したので神が決めた運命の人を探します～

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)
