Storyline
In the barren world of Vulvaldia, swordswoman Rachel Sparkle works as an adventurer, accepting various requests from the local Adventurer's Guild. Her routine changes when she is sent to investigate a mysterious portal.
When Rachel approaches the portal, its barrier suddenly collapses and a powerful figure emerges from the other side. Rachel soon finds herself caught up in a conflict involving the Demon King Charlotte and a mysterious world-threatening force.
Rachel joins forces with Christina von Raincast, and together they begin a journey to protect seven powerful crystals scattered across the world. Their quest takes them through several regions and towns, where they encounter dangerous monsters, hostile rulers, mysterious dungeons, and increasingly powerful enemies.
As Rachel and Christina continue their journey, they uncover more about the forces behind the crisis and eventually return to the portal where their adventure began. Their final confrontation with Charlotte will determine the fate of Vulvaldia and the world they are trying to save.
