I feel so bad for Saru. Once there was a time when he was ranked the strongest hokage. But all we've seen him do is the shadow shuriken jutsu... I'm not exactly sure if he is able to summon Enma but it's possible since hanzo had his salamander. But I do see him in the future interacting with Ohnoki in some way maybe as to fight together or to have a funny chat. Either way do you feel bad for the 3rd and are disappointed about how things are going for him. Or do you want to see more of different characters.
