I used temari(swimsuit),naruto(sosp),normal gaara with wind main.If you are hella lucky and wind main doesnt get immobiled you have a high chance to win.I'm at 195k power and im the first who beat it so the difficulty is normal.Use temari on pos2 with your good gear and naruto pos1 so you can stop hiru on the first ''wave''.Talents: 3-2-1-3-4 with katsuyu as summon.
