Inari Saionji, the eldest son of the Saionji Marquis family, immediately regained memories of his past life after turning fifteen.

This was the world of "Call of Magic Knight," a game he had thoroughly played. And to his surprise, he was... a character loaded with attributes: a narrow-eyed, villainous noble affecting a Kansai dialect.

He began to act to change his utterly miserable fate: one where he thoroughly provoked the protagonist in the early stages only to suffer a crushing defeat, and was then effortlessly vanquished even after abandoning his humanity.

His goal: to defeat the protagonist in the event battles he was destined to lose, and continue provoking him until the very end.

Through his life as Inari in this world, he had developed a surprisingly good nature. He honed his unique skill, Demonic Sword Creation, and aimed to become the strongest.
