Shinji Watari is a second year libero in Aobajōsai High. His skin is quite tan and he has a black buzzcut. He has gray eyes. He seems to enjoy being challenged, due to the fact that he smiled when Nishinoya used the same move as him when he set from the back row. It's shown that he can be very gentle and supportive when he tries to cheer up Kyōtani after he misses a point, regardless of Kyōtani's lack of proximity with the rest of the team. Before he became the libero, it was mentioned that he was actually a setter. However, it's unknown if he has ever played as a setter in Aobajōsai High.
