I know the body pillow has someone from Blue Archive, and I think that's another Blue Archive character next to the Steam Deck, but it seems trying to figure out who they are while having little knowledge of names on here isn't easy.

I also think the figurine on the table is Yumemi Riamu from Idolmaster but not being able to see the inner hair (Yumemi has blue on one side) makes it hard to tell.
