as you can see in this screenshot, you noticed that his base power in arena is 19k.. so supposedly he used 3 ninjas in his own and 1 for ninja trial(?), right?

wait.. if he used 3 ninjas, then who's in the ninja trial?
*kurama? (possibly no)

*what about 5ks? (you think he'll be put in ninja trial?)

*normal sasuke? (I think not, 'cause as you see his sasuke has breakthrough skill)

something is not right
