I don't quite recognize all the stuff in this image. The Tachikoma and TLOU cover I got for sure. It looks like it might mean to say "Velvet Room" over the door, so I added the Persona tag. I think that cat with a crown might be a Final Fantasy thing, and the reflection in the mirror might be related to the American McGee's Alice but I'm not sure on either. No idea if the masks on the wall are from an actual Sentai series or a parody from an anime
The masks on the wall are the Power Rangers. Also, the yellow thing in the black hat is Cheese-kun, Pizza Hut's Japanese mascot.
