Main article: Academy Entrance Arc On the day of the entrance ceremony, as everyone began looking for an absent Boruto Uzumaki, he suddenly appeared, crashing a train into the Hokage Monument, which left Tsuru amazed at his antics.
School Trip Arc
Graduation Exams Arc
Main article: Graduation Exams Arc During the graduation exams, Tsuru was knocked out by Konohamaru Sarutobi, alongside Renga Kokubō and Hako Kuroi, leaving all three of them unconscious. With Kakashi as the only obstacles left, Tsuru and the others faced him. Despite their group assault, Kakashi easily repelled all the students. This however proved to be a setup to get the Sixth Hokage in a group String Light Formation. Despite their effort, Kakashi was still able to hold them off. Ultimately, time ran out with no one getting the bell. However, Kakashi still chose to pass everyone as they succeeded in the test's true goal; teamwork and loyalty. Afterwards, she was placed on Team 40 alongside Enko Onikuma and Dōshu Goetsu.
Byakuya Gang Arc
Main article: Byakuya Gang Arc With the continued thefts performed by the Byakuya Gang throughout Konohagakure, Team 40 was assigned alongside the other genin teams to help stop the self-proclaimed noble thieves. However, the genin were not permitted to engage the Byakuya Gang without aid from a chūnin or higher-ranked shinobi.
Versus Momoshiki Arc
Sometime later, Enko's secret technique acted up, injuring her jōnin leader. Eventually, Team 40 was assigned Ibiki Morino as their new team leader. However, he immediately decided to disband Team 40, viewing that Dōshu and Tsuru's continued fear of Enko's power would only inhibit performance and instead decided to train Enko personally as an interrogator.
Wanting to help their friends, Boruto, Sarada, and Mitsuki began helping Tsuru and Dōsho to master their fear, hoping to convince Ibiki to reinstate their team. After their various attempts failed, Tsuru and Dōsho found stray cat. Despite being friendly to it, the cat was scared of them and ran from them. This experience helped Tsuru and Dōsho to understand what Enko must go through all the time. Later, they chanced upon Enko going berserk again while Ibiki struggled to detain her and even considered cutting off her arms. Knowing that her rampage came from her feelings of loneliness, the two were able to reach her, insisting they won't leave their friend. Their genuine friendship ultimately calmed her down. Ultimately, Ibiki conceded that the three genin together would be best for Enko and officially reinstated Team 40.
