Avatar item ideas:

- Tuxedo and Wedding dress unlocked after giving any Lover a Diamond Ring. The player can be the waifu!

- Morpheus' coat after reaching over with Elle. For a double reference, the collar and shoulders could be based on Morpheus from The Matrix while the tails could swirl into tattered shadow like Dream of the Endless from The Sandman.

- Frosting smears (imaginatively placed) after reaching Lover with Bonnibel

- A trail of bloody footprints after reaching Lover with Ayano

Mio: I dunno, the iconic obvious choice, Mario, doesn't seem like her kind of game. Maybe reference Tron or The Last Starfighter.

Can anyone come up with others?
