I'm playing Shinuyama currently so I'll comment this a bit later but what I have to say now is about Kappas:
First, they're absolutely inefficient above the waves as they get 5 fatigue per combat round.
Second, they're really cool underwater and tear almost everything apart but die from poison very quickly (very orthe it happens after battle). It requires very thorough placement to use them efficiently and not gather empty turtle shells after battle. They should strike first and kill as much as possible in first combat round. Then you'll have a chance not to lose them to tritons or atlantian spearmen.
Third, they have rather poor MR 8 so you don't want to use them when magic starts ruling the batlefield
