The last ally event which is available to you after you've completed the B rank tournament. To begin it, go North from the save point on the Festival Plaza (Rank A Map) - the place is marked on the map as Great Eagle Cliff. Start the conversation, and after a short while you will have to defeat them both in two rounds.
The first one to fight you is Fuu. She's a mobile enemy, who will be extremely annoying for you if you are playing with a strong, but slow character. Her weakness is that her attacks deal very little damage - she will have to hit you multiple times for you to even bother. The second enemy is Yugito. If Fuu, during your previous fight, wanted to gain any distance from you, Yugito will try to fight you in close combat, all the time. She has the same strengths (mobility) and weaknesses (low damage) as Fuu. As always in those kinds of fights, you have a huge advantage over your enemies - you can use your support, while they are fighting alone. As both of them are fighting with their Awakening Type, don't let them use their True Awakening - they will turn into their tailed beasts and the fight will become a lot harder.
After you've defeated them, the event will be finished. You will be given:
- 3000 ryo
- 2x Large Chakra Renewal Band
- Ninja World Tournament allies: Fuu, Yugito Ni'i.
