What an odd Greninja......
Well, even so, having them as an additional party member for this Cross-Over Space shouldn't be too much of a problem!
Ettoo.. Aren't they coming on a little strong though? Well it's not the first time I've met a strange party member!

In a similar manner to Role Play and Protean, it looks like when Alex the Greninja wears different outfits, his affinity shifts!... It seems like his personality undergoes an shift as well, leading to quite the interesting results!

Alex from  Greninja_Senna! Thank you for the commission~
