Isekai Tensei Soudouki

In the Kingdom of Mauricia, Bard Cornelius has fallen ill, and the reason is because two different people have been reborn into his body. He has his own personality as “Bard”, and there are two other personalities too! A miserly feudal warlord, Sadatoshi Okasanai, and a nerdy high school student, Masaharu Oka, who has a fetish for animal ears!

Three souls as one; he is able to fight, start his own business and manage the lands with such competence as if he's using cheat codes…!
