Maiden's Mystery Chest

Hidden deep within an ancient dungeon rests a mysterious box sealed by powerful magic. No one knows what lies inside until it is opened. When the seal is broken, the box summons a random girl from another world whether she's a loyal maid, a skilled elf, a powerful mage, or someone even rarer. Every opening is a new surprise, and fate decides who will answer your call.
