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 Gen amazed at his antics.

Later, his class was assigned from Shino to shadow a non-shinobi workplace to better understand its lifestyle.

Gen and his class went to Kirigakure for a field trip, where they were greeted by their tour guide, Kagura Karatachi.

Graduation Exams Arc
When Shino's class had the opportunity to become shinobi, Gen chose not to participate in the Genin Exams. Instead he returned home to take over his family temple.
