Bleu has the most useless ability. When in a hunting field she can turn everything into charcoal. Charcoal is useless so her ability is worthless. She does get an awesome in battle ability called Shed. Shed restores all her Hps but I think may lower her defence a bit. Not 100% sure on that. Sadly Bleu also doesnt have any Shaman combos.
Onto the positive things about Bleu. She has very good stats in almost everything but her guts. She gets most Black Magic spells and comes on Lv 36 when you first get her. I personally think Nina is just as strong but Bleus very good to have on your team.
