I don't think Chirico has something that uses Skill stat.
Just try playing SRW A P.
I think he was more trying to understand because your first sentence says there is no such thing as a hard SRW, then in the next you say SRW A Portable is infact hard.
Dd you mean there is just no hard SRW in the Z series? Or in general and A Portable is an odd rarity?
