Mermaids (Patreon)

Naritsa the Mermaid finally gets to swim in a real lake after having to live in a city for a long time.

This takes place during the Chain Girl's' Expedition to the North. 

Naritsa has a surprise encounter with a secretly transformed Renée (It's a complicated story which we will get back to later).

Another mermaid, from the Maid campaign. The students of the magical school throw a theme party with some of the participants transformed into mermaid waitresses.
