I beat that instance as a Fire Guy, with tremendous buffs to my ninjutsu (Mood, Magatama, Mood Scrolls, Only ninjutsu skills, etc.), and Tobi/Chiyo combo :D + Hinata for tankiness :)
Fun Fact: Chiyo can ressurect Tobi xDD He is still there after death, just his sprite is made to look like he's gone :)
what power when you beat it? did you made it to full battle points?
For the blue circle inside, you need to interupt Hidans ult in the second round and kill Kisame before he specs. other then that its pretty much gogo, i did it around 19k power.
