Their relationship isn't being treated as a femslash ship but more like a friendship, due to the fact Paimon's appearance seems like a young girl and it can get controversial if Lumimon is treated like a femslash ship. This also includes Paither as well since Aether and Lumine are both siblings, there are lots of fanarts depicting the two. There are currently over 380+ gen fanfictions that includes the two on Archive of Our Own.

There's also a popular theory that Paimon is the unknown god due to the fact Paimon's appearance is also a bit similar to the unknown god. Making that, Paimon willing to betray Lumine at the end of her journey leaving into her sadness and betrayal since she was her companion and was always there for her even though she may be useless on her journey.

In fanfictions, Paimon is mostly portraited as a wingman or a third wheel to Lumine and her respective ship.
