Graduation Exams Arc
During the graduation exams, Hako was knocked out by Konohamaru Sarutobi, alongside Tsuru Itoi and Renga Kokubō, leaving all three of them unconscious. Later, following Boruto's plan, they were able to eliminate the other proctors and face Kakashi Hatake to take the bell from 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. Later, she was put on Team 25 alongside Hōki Taketori and Renga Kokubō.

Byakuya Gang arc
With the continued thefts performed by the Byakuya Gang throughout Konohagakure, Team 25 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.
