The Drain Lab (ドレインラボ Dorein rabo) is a laboratory hidden underneath Fairy’s Island. Created thousands of years prior, 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.
