The immensely popular VRMMORPG, Crest Online (Creon), is an action game where players fight against various strong enemies using the crest they chose during character creation as a weapon. I, the world's number one ranked player in Creon, was suddenly reincarnated 1000 years into the game's future. Reborn as Zelos, the second son of the Sylphid Marquis family, I received the "Null Crest," a useless gift that everyone despises. Despite the disappointment of my family and the ridicule of my brother, I, with my memories and knowledge from my past life, know that the Null Crest is the "strongest ability" capable of learning all skills. I aim to become the world's strongest once again in this world! Using my game knowledge and the Null Crest, I rapidly gain strength, surpassing even my past self and becoming the strongest, dominating this world.
