Tenmoku Sho, a former Shinto priest and chef who was reincarnated into another world, was born as the Fifth Prince, Elroy Norgard.

Based on his memories from his previous life, Elroy gained renown as a prodigy, but this only made his elder brothers wary, subjecting him to harassment and slander until he was isolated.

As a result, he was exiled to the frontier region of Uroborosland, a desolate land said to be a certain death sentence.

However, Elroy, now freed from the entanglements of the royal palace, was rather pleased to begin reforming the frontier into his own personal kingdom.

Yet, for some reason, his brothers' wives, with whom he once had good relationships, began arriving one after another, seeking his help.
