   Summary

   Muelsyse, Director of the Ecological Section of Rhine Lab.

   You know who she is. But did you know that she’s done all the girl directors, no exceptions?

   Each chapter will feature a different escapade between Mumu and one of the Rhine Lab operators. Much of Muelsyse's characterization in this fanfic is inspired by UOF's (@uof1052237) depiction of her in their illustrations, right down to the many shapes water can take ✨
