Ah, so you haven't watched Galaxy yet? I hope you enjoy it, because it's easily my favorite of the GO series (especially in the early episodes). The characters are great and it brings back a lot of the "zing" that was present in the original Inazuma Eleven series (well, it feels like the original in a lot of ways).
That, and female characters get a lot more focus and variety than they ever have before in the series- it's actually pretty refreshing.
