Nyen and 2P Nyen
I drew the illustrations for everyone except Nyen myself; my art style is not consistent at all. I tried to make it look official, but it was difficult. The 2P Nyen on the cover is a bonus; I might make more if there are requests... I might change the profile settings later. Relationship is up to you.
