Summary
In the Kishimoto portion, Mitsuki discusses the heritage of the members of Team Konohamaru. Konohamaru Sarutobi is the grandson of the Third Hokage, nephew of a member of the Twelve Guardian Ninja, and son of two members of the Anbu. Boruto Uzumaki is the son of the Seventh Hokage and the "Byakugan Princess". Sarada Uchiha is the daughter of the last survivor of the Uchiha Clan Downfall and a disciple of the Fifth Hokage. Before he can explore his own heritage, Mitsuki runs out of page space and encourages readers to watch the movie to learn more about him.

In the Taira portion, Konohamaru gives his team a bell test. Misunderstanding the objective, Mitsuki stretches his arm and grabs Konohamaru's testicles, leading Boruto to wonder if Mitsuki's father is Monkey D. Luffy only to stand corrected by Mitsuki. Konohamaru escapes and prepares to attack with the Rasengan. Boruto counters with a similar stance, which Konohamaru initially believes to mean Boruto has already learned to use the Rasengan as well. Instead, Boruto squeezes a lemon in Konohamaru's eyes. While Konohamaru is down, Boruto makes three shadow clones and they defeat Konohamaru with the "Seductive Adult Four Technique". Mitsuki is impressed, but Sarada, embarrassed by everyone's behaviour, pummels Konohamaru and Boruto and takes both bells for herself.
