normal setup for fire main on nine tail event :

main - x - anko
guy - x - x
tenten - x - x

skill : 22131 summon : piggy (yeah he does alot of damage to ninetail, don ask me why)
tips : dont auto, use manual instead
tips 2 : if anko cant soak damage from ninetail, use main clone to tank

How to use this formation
1st turn - activate anko barrier
2nd turn - use main skill
3rd turn - use guy skill, then after main attack; use anko skill
4th turn, use all skill available minus anko

i dont own this setup, found it in forum so credit to whom 1st post it tho.
