Fire main

1st round dont use sakuras mystery, cause you are ignited and ignite doesnt go away with healing. just endure the dmg and proceed.

2nd round use sakuras mystery and just make it through the rounds it wil be easy as you will get full hp.

3rd round vs danzo just kill all the other guys let danzo aside and when hes gonna use izanagi to someone else except his self then go and burst him.

4th round is clearly good wait them to use their skills both of them and then use sakuras mystery again if shes not chaosed. and then use every mystery you have against them and its over.

Earth Main

1st round endure the dmg dont use sakuras mystery.

2nd round you use sakura and just let her slugs heal you while you slow killing the puppets.

3rd round hit the other guys until danzo change his target with izanagi and then focus him and kill him.
