The final battle Naruto VS Tobi epic punch with the last achievements i needed
- Hero of the Ninja World
- Conquered Formidables
- Consummate Storm Master

This battle is EXTREMELY difficult to S Rank if the right precautions and methods aren't taken, as it is a 4-part battle with individual ranking, for an overall rank. Primarily you'll want to bring plenty of healing items! By this point, depending on how far you've leveled your Hero palette, you should be able to use All-Purpose Ointment or Wonder Elixir. HEALTH is a MAJOR, if not only, factor is obtaining an S Rank across ALL of these battles, so be aware of it and heal only when necessary.

First off, you want to pick the Hero sideline. Secondly, eat the bento that gives you Max Strength/Damage + Full HP and bring along a Hero Build of all Health Items that are maxed.

The key is that at the end of the fights you need to heal to max health or close to it for the bonus. As naruto vs the tailed beasts if they shoot ranged at you then press Y+X to throw out a strong shuriken. If its in line it will cut through there attack and also do damage to them, and of course use Killer Bee as much as you can during the 7 tailed beasts.

I would take full advantage of the chakra dash and punching, Fuu's tailed beast (The flying one) I just Y + X from a distance and let Bee do the damage, much safer.
Also when a Tailed Beast is charging their Chakra for a special attack, delaying them with a few windmill shuriken and use Killer Bee to interrupt and cancel the attack.

After all that, when you're Kurama. Use Y+B to do your Tailed Beast Cannon move. This will kill the tailed beasts in 2 shots.

Hope this helps!
