Koitsu ni Dakarenakya Harapeko de Shinu Rashii: Narikawari Incubus no Maou Henjou Keikaku

A brilliant lawyer was working late into the night on a case when something strange catches his eye. His hands are becoming transparent...?!He dismisses it as exhaustion, but the transparency creeps up his arms until... He suddenly finds himself in an unknown world. In a room resembling an ancient castle, he was unsettled by the dim, eerie light. When a strange voice called out, "Lord Zofi," he turned to face it. Looking into the mirror, he was stunned to see... A tail? Horns? And these scandalously revealing clothes?! Wait... Is this me?! He soon learns he's in the demon realm, having switched souls with Zofi, an incubus next in line to be the Demon Lord. Before he can even process this revelation, a formidable demon named Belial, who practically embodies the word "monster," pins him down. Kudou must adapt to his new life as an incubus, including their unique dietary needs and the strange demon culture. His only chance of returning home is a joint scheme with Belial to make him the new Demon Lord instead. But maybe things won't go quite as planned...?
