______

I am not gonna list my equipped jutsus' list because you are having default ones in the start.... But equip the best ones available.
Don't forget to equip Nine-Tails' Chakra jutsu. It is handy in this mission most of the time.

Well after these things settled up, get into a battle with Shukaku. Cloak yourself with Nine-Tails' Chakra and recharge your NORMAL chakra, after that go ahead and beat him up!

REMEMBER: This one is important, keep an eye on Hinata. If she is in front of Shukaku's Attack and you are on other side of it (Safe side) then quickly navigate the 'Assist' arrow on Hinata and press the Square [] Button to get her away while the command is to assist you with her attack. Because she is the only healer there !

Also if you want to get the scrolls which you don't currently have, try completing/replaying the free missions and old story missions.
