Shoji was present when Aang first got in a confrontation with Hide. He was very surprised when Hide did not get in a fight with Aang, and proceeded to invite Aang to play a game of hide and explode with him and his friends to which the latter agreed.
During class, Shoji was stunned by Aang's behavior again, first when Aang dared to speak up against Ms. Kwan and later when Aang began dancing violently during music class. When Aang asked whether or not people danced in the homeland, Shoji silently replied that they did not really do that. This gave Aang the idea to host a secret dance party in the cave in which rest of Team Avatar was staying, to which Shoji was later invited. Shoji was, however, unsure about what to do after Aang introduced The Flamey-Os. Aang tried to explain that dancing was "a form of self-expression that no one [could] ever take away from you", but Shoji stepped up and told Aang that, while it might be different in the colonies, people of the main land just do not dance. When Aang demonstrated some classic Fire Nation dances, like the "phoenix flight" and the "camelephant strut", Shoji and another male student were utterly shocked and impressed by Aang's dancing. When Aang invited everyone to "freestyle", Shoji's movements restricted themselves to a rhythmic nodding of the head.
After the party was discovered by the Headmaster, Shoji was the first to put on a headband to help camouflage Aang. He winked at Aang as he left and was shocked when the tunnel Aang disappeared through was suddenly closed with earthbending.
