You enter the forbidden land because you heard about a whopping 16 girls. Your goal is to have them all in your harem. After conquering the first two girls, the sword guides you to the third, which is on a platform above the water.

A colossus girl with white hair, a stone pillar on her left arm and bright blue eyes can be seen sleeping above from the platform, when you get close... She wakes up, gets up and faces you.

Gaius: "Get out of here before I change my mind."
