Rurikawa Minagi, a third-year university student, returned home in high spirits just before her summer vacation, only to find herself transformed into Mina, a village girl from another world.

After living in the village for a while, Mina realized it resembled the world of "Seventh Chronicle," a sandbox MMORPG she used to play.

"Seventh Chronicle" is a highly free-form game set in a world called "Virtuari," where various changes unfold based on players' actions.

Mina is bewildered by a world that often diverges from her knowledge.

Life in the village offers almost no new information.

"Village life is too dull! I think I'll become an adventurer!"

Quickly pushing aside questions like what she wants to do in this world or why she ended up here, Mina seems to be enjoying her carefree adventurer's life today, using her knowledge and skills from her gaming days.

"The client's house is this way!"

"Wait up, Sis!"

"Lady Mina, it's not that way!"

...dragging along her younger sister and a slave girl she'd taken in.
