I'm Scarlet, but I'll try ^_^

I'd do Shark Bomb over healing, just since it's 4 rounds and if you survive Exploding Hell you don't have much longer anyway :(

Same goes with: whip over heal, shark bomb again (compare the damage of those two?), Water Enhancement (Kyuubi can't be poisoned), and I'm not sure what Soul Absorption does but if it's damage causing go with that.

If you have another summon throw it in the third slot for more power. And change the summon based on your team choice.

And... um... since I suggested Water Enhancement maybe go with a water team, unless that just doesn't work for you? Otherwise, I'm not sure I can help until I know what the chase conditions->results are for your main's talents, sorry.

You c*e Haku + Tenten + Guy with Talents 2/3/d/1/1. Put Haku in your Move 1 slot, so he launches a barrier and don't dispel it till Turn 4.

Note: The "d" in my Talents description is "don't care", since the Nine Tails is immune to Knockdown, Repulse, Low and High Floats, all of Azu's Chases are worthless :P

Pick shark, flowing whip, water enchancement and water clone. Summon can be any, because its not rly important.

Main---Haku---Clone
Guy--------------------
Tenten----------------

Guy isnt very good in this comp, much better someone like suigetsu who can do double water attack each round, but at least he can buff a bit whole team. You c*so use someone like sakura. Damage ll be lower, but higher survivability if you need that. Also make sure water barrier indeed buffs team, because i heard 2 stars chars can be bugged.
