Currently one of the better units in the game. Because of his attribute as well he is not bad against any units. He has both very good HP and ATK stats at 1136 and 1355 making him a must have for most people.
Jutsu:
His Jutsu is an AOE and does 2710 damage to each unit he hits. This isn't a great amount of damage considering it is a 5 Chakra Jutsu and because of how high his base damage is but with the ability to have a chance of sealing the opponents Jutsu by 25% can become very useful. His secret technique on the other hand is very powerful with damage dealt at 8943 to a single unit without any modifiers and then heals you between 7% - 10% of the damage dealt which is great if you lack healing characters.
Awakening:
Special awakening materials are needed for him to reach 6* so bare this in mind as you will have to wait for the event to come to be able to do this but overall he is recommended.
Pros
High base stats
Not weak against any other units
Very powerful secret technique
Chance of your teams Jutsu being sealed reduced by Field Skill
Cons
Jutsu and secret technique are a little high so might need to stall for them and normal Jutsu is over shadowed by the secret technique
Thanks to bfw182 for his awesome evaluation notes!
