TBH.. Everyone who keeps whining about it being unfair are chickens.. I unlocked it today and beat it today.. Using unorthodox characters which do come in handy lls.. The game is reliant on strategy.. IF your playing it for the beauty of it.. Drop it.. btw.. I used Wind Main, Gaara, GNW Kankuro and SN.. but in all my *ity I switched to water.. but * still worked out lls.. And for the next event.. Just replace Gaara with Iruka for those double interrupts
