Other side (My version)

Otherside is a traveler who can go into any universe. It is unknown why she can travel to any universe. She often tells stories about her travels to the other music discs

OS (my ver): I am a mother with four children-

(I call her the "mother of allays")

Nice (Also, my version of Otherside is that she likes Allays and even has one as a friend)
