Thanks for the attention.
Cavalier
Boon: Strength
Bane: Luck
I think this is it.
edit1: I'll try focus in Hinoka.
Edit2 (YouSquiddingMe): I don't unlock Ryoma yet, but a friend told me that him is good.
Edit3 (Funky Tim): So I'll focus in Ryoma, Kaze, Azura and Hinoka. Azura has already married with my character, I think that helps a little more. She's awful attacking. I let her just giving support and singing.
