- This only works for Hinata, Shoma and Boman. 

On the character select screen go to either Boman, Hinata 
or Shoma, whoever you want to play as. Hold START and select 
them with Y, B, X or Y button (If you try to make different 
colors by pressing A+B for example, it won't work) Hinata 
wears the same outfit except she has sleeves, Boman has no 
shirt and Shoma wears a jersey kind of shirt.
