In a world where VR technology has become widespread.

A certain game announces the termination of its service.

Yuuki Tachibana logs out, lamenting the end of the game and the comrades she had shared it with.

Then, she receives a message from a former guild member.

It's an invitation to a game being advertised as the first domestic VRMMO, currently seeking beta testers.

As she reads the official website for 'GRIMOIRE ONLINE', a game based on fairy tales, folktales, and myths,

she recalls the knights protecting princesses, heroes battling dragons, and divine conflicts she admired as a child.

In a game that allows her to experience such a world, she begins to weave a new tale alongside her former companions.
