The six-year-old Shiro Weimiya has not yet started four battles and his parents are still alive.

very good! The next step is to stay away from the Four World Wars, refuse to be a partner of justice, rely on the grasp of the future direction, embrace huge wealth, and reach the pinnacle of life.

Rescue the parallel world where Da Yuan is gradually disappearing

Smash the conspiracy of the Demon King

Save pan-human history

My path seems to be getting worse…

PS: Four battles → Garden of Avalon → Magic → FGO Five Wars → ? ? ?
