Shū is a small cat with white fur and light-coloured eyes. He has a brown tail and a circular-shaped brown fur marking right above his right eye.

Search for Tsunade
When Naruto sees him playing with a water balloon, he gets the idea to use two hands to create the spinning motion for the Rasengan.

Video Games
Shū appears in the updated in Naruto Mobile as a tame beast assisting the owner in battle. He rolls Explosive Tag Balls in the manner of a ball, which prompted Naruto how to properly practice using the Rasengan, and then directs it under the feet of the enemy.
