Upon hearing that he and the rest of the class will be going through graduation exams in a week, Mitsuki eagerly said to Boruto that the day has finally arrived, to which Boruto agreed, claiming it would be a piece of cake. He later ran into Chōchō and Sarada at a restaurant and had a little chat with the girls, noting that questioning their identity and self-worth is common for girls their age and is commonly referred to as their "tragic heroine syndrome". Mitsuki was also able to determine from which clan Chōchō hails, not only from seeing her family crest but based on her appearance as well.

Later, Mitsuki joined Boruto in a simple errand of deliver lunch to the Hokage from his wife for the trip. After arriving too late, Sarada and Chōchō offered to leave the village and bring it to him. While Boruto felt it pointless, he soon saw the strong desire in Sarada's eyes. Mitsuki, also realising this was important to the young Uchiha, asked Chōchō to give them a minute, who wondered if this was a love confession from the boy. Mitsuki simply replied that her symptoms were getting worse.

Quotes

 * (To Chōchō and Sarada) "That is commonly referred to as your tragic heroine syndrome. The condition is said to afflict young girls of a certain age who lack a certain self-awareness as they try to establish their sense of self… Well… that is if you care about such trivial things."
