Black Lily Waterpark

The Black Lily Waterpark is a waterpark in Japan owned by the Black Lily Advanced Materials Laboratory.

The park was built on a site that originally only had a small closed down pool but Mr President bought the place sometime before Chapter 81 for cheap and renovated the whole place into a Liminal friendly health resort, which is also open to humans. Suu's mother was instrumental in the construction of the water park, not least because of her ability as an Undine to create infinite water, which reduced the park's water bill to zero.
