For those not familiar with the game, The World Ends With You (TWEWY) is a DS game made by Tetsuya Nomura (Kingdom Hearts, Advent Children, VS XIII).
Skipping over the details of the game, within it there are a plethora of buttons that you wear to set up your attacks, and these buttons have very stylish and distinct designs.
Of course, a request for all of these would be absurd, so I’m only bringing up the idea to make maybe a few distinct ones. Such as, the Player Pin, some currency pins, Noise (enemy) pins, etc. Really just about anything would be great, and considering TWEWY’s large fan base, I’m sure they’d sell out in no time.
