I kinda like how this doujin gave us a small reference to that Ghostly field club track “strange bird of the moon, illusion of the cat”... I don’t remember the name of it, but it is interesting that while some may think that the bird may refer to Renko and the cat may refer to Maribel, in the part where Remilia talked with “Maribel” she also called her a strange bird instead of a illusionary cat. Meaning that Maribel is the bird of the moon and Renko is the illusionary cat, that merry is both the bird and the cat (meaning that Renko is left alone yet again without an animal theme... outside of rabbits or course, which then tied with Maribel having a theme of sheeps), or maybe the strange bird of the moon is referring to Sakuya?
