Just say you spent a little bit.
You're either f2p or not. Pshhh. ;P

As for Minato . .. I dunno . . .
Does he even have a chase? lol. . .

I think I saw someone using him on my server with an AoE wind team . . not a lot of combos, but it hits hard due to mysteries and AoE. . .and his high power. . .
It was something like S. Naruto, Minato, Wind Main . . and someone else. . eh

Well yeah.
Spends money. Calls f2p. OK lol
