Multiverse: Starting as Killer Queen

All Roland wanted was a quiet life—working his convenience store shift, home by 8 PM, eight hours of sleep guaranteed. But fate had other plans. Transported to 1994 Fuyuki just as he awakens his Stand ability, Roland finds himself caught in the deadly Fourth Holy Grail War. Serial killers, master assassins, and the infamous "Mage Killer" keep disrupting his peaceful routine. His solution? Simple and absolute: anyone who disturbs his tranquil existence must die. One man's quest for normalcy becomes a ruthless crusade in a world of magic and mayhem.
