Arthur Grail, a hardcore player of the VRMMO Trinity Star Online, woke up one day in the body of Gerard Astoria—a petty villain fated to die before the main story even began. To make matters worse, Gerard's death was a crucial event in the game's narrative. If he didn’t meet his predetermined end, it could disrupt the story entirely, leading the universe toward one of the countless "bad end" routes!

Unwilling to leave his fate to chance, Arthur decided to take matters into his own hands—recruiting the "player" as his partner to help him clear the game and rewrite his destiny.

But wait—"Why is the player not a dude but a sharp-tongued beauty instead?!"

Follow Arthur's odyssey, filled with trouble at every turn, as he works to uncover the mystery behind his awakening in a universe eerily similar to Trinity Star Online's setting, all while trying to save the entire universe… without forgetting to enjoy himself!
