Mori appears to be quite timid and lacks confidence in himself.
Mori was one of the three first years who joined Yukigaoka Boys' Volleyball Team in Hinata's third year of junior high. They attended the Junior High Athletics Meet, but Yukigaoka was paired against the tournament favorite, Kitagawa Daiichi, in its first competition. Mori and the other first years immediately lost confidence and were easily overwhelmed in their match. Yukigaoka lost to Kitagawa Daiichi quickly.
Mori seems to be a beginner at volleyball and has poor receiving skills.
Hinata was Mori's captain during the latter's first year in the Boys' Volleyball Team. Despite the first years lacking confidence in themselves and expressing fear of their upcoming matches, Hinata remained optimistic and encouraged them to do their best. Throughout the match, he made sure to cheer up the first years whenever they made mistakes. Mori didn't appear to be affected by Hinata's motivational efforts though.
