A man reincarnated into another world. Leveraging his in-depth knowledge of a game he mastered in his previous life, he struggles to survive, protect his family and territory, and ultimately alters even the fate of the villainess.

Born as the child of a noble, Ars displayed talent from an early age, and by the age of ten, he was hailed as a prodigy. However, a certain secret lay hidden beneath the surface...

"Huh? Don't tell me... is this world I reincarnated into Greacias?"

Ars was, in fact, a reincarnator. Moreover, his destination was Greacias, the world of a game he was obsessed with in his previous life. This game was notoriously difficult, known as a "brutal game" with a terrifyingly high difficulty. To make matters worse...

"Wait a minute, a large-scale war is about to break out across the entire kingdom!"

By the time Ars realized it, it was already too late. The "War Event," a pivotal event in Greacias, was fast approaching.

"I can't just stand by! I must act to prepare for this event!"

To overcome the imminent war and protect his family and loved ones, Ars must leverage his cultivated game knowledge. Can he achieve a feat no one else could?

He refuses to be a mere background character. Witness his magnificent ascent.
