Character recommendations
Naja is the strongest with close range combat ( [A] attacks) and can charge magic (hold [X] + [R] ) about two to three times faster than any other character. Regardless of her stats, she also has relatively strong magic and she is the fastest person. Her only drawback is that in story mode, the Bosses are more difficult.
Shiga is strong, but not as strong as Naja. He is fast and his magic is also acceptable (Tornado magic recommended). He is fast and this is a good advantage.
Tai is good at close range, but not as good as Naja. His magic is also second best. However, he is slow.
Lani has the best magic and has relatively good speed but she has the worst attack.
