I don't know what he want

Gaara the monster or Gaara when u fight with Sasuke in the compotition?

Anyways ill give u the answer for both...

Gaara the monster- after that u finished the game all u can do is leveling to level 99
with all the charecters.

Gaara in compotition- You need to go to some new forest & find Orochimaru & beat him then
you need to find Sasuke with Naruto, Sakura & [Anyone you pick] & wene you find Sasuke you
will be back with Naruto, Sasuke & Sakura then just go down (I sugest u train a little
then go down) you will fight with Gaara's Team(With or without gaara) (you'll easylli win
if you used my sugestion...) Win 'em then you'll automaticaly go to gaara you see him
turning to a monster you'll fight him win him & if you ask "What next?" so rea wht if
before the "Gaara in compotition"
