Drain Lab

The Drain Lab (ドレインラボ Dorein rabo) is a laboratory hidden underneath Fairy’s Island and used by the Seekers of Truth.

Description
The Drain Lab was created thousands of years prior to the present of the game. It is used by Promestein to not only experiment on humans, but also to extract their semen, hence the name. The laboratory is so secretive that not even the residents of Fairy’s Island, including Queen Fairy and Queen Elf, are aware of its existence.
