In the modern era, a young man passed away, but was reborn in another world as "Eldo." Coincidentally, this world resembled the virtual reality game he had played before his death.

His familiarity with the world's mechanics came from his previous experience and understanding of its data. With this advantage, will his reincarnation be the key to his strength?
