"A Tricky Assignment" (厄介な宿題, Yakkai na Shukudai) is episode 255 of the Boruto: Naruto Next Generations anime.
Synopsis
In Konoha, Naruto congratulates Team 7 for their success in the Land of Water, having already been filled in by Chōjūrō. Katasuke was impressed by Boruto's willingness to risk his life to end the conflict, which has bolstered Konoha's reputation. Shikamaru explains that the Funato lost much influence and have been placed under surveillance by Kirigakure. Gokai, Kobuna, and his mother visit Funamushi's grave. Gokai promises to raise Kobuna into someone Funamushi would be proud of. Kobuna wants to be strong to protect everyone. Jibiki, still distraught about Isari's death, as well as Araumi, have been imprisoned. Boruto asks about Ikada, Naruto telling him that Chōjūrō made no mention of him. Naruto and Shikamaru speculate that due to his position and involvement, he's likely to face charges. Boruto wants to contact Chōjūrō to confirm Ikada's status. Kawaki sees nothing wrong with Ikada facing punishment, as he was a commander. Boruto points out that Ikada stopped the fighting, and that resentment over punishing him despite that might spark the conflict again.
Kawaki reminds him that Araumi aimed the Chakra Cannon at both Boruto and Ikada, finding Boruto's outlook too naive. Boruto and Kawaki keep arguing over the cycle of hate and revenge. Kawaki leaves and comes across Team 5. Iwabee deduces he fought with Boruto based on his mood. Denki has to stop things from escalating, and they recall Kagura's wishes. Kawaki finds them naive as well. In Kirigakure, Misuno hands Chōjūrō damage reports, which they'll need a lot of time to recover from. They also discuss the great loss of lives as well, including the daimyō's son. The daimyō has requested harsh punishment for ringleaders Araumi and Ikada. Chōjūrō understands it but is concerned about further antagonising those who supported the Funato, concluding that the Land of Water modernising too quickly created the strain that led to this conflict. Naruto and Boruto talk about what he went through in private. Naruto relates to how Boruto feels, having gone through something similar. He tells Boruto to patch things up with Kawaki. Mitsuki checks up on Kawaki, feeling that Kawaki had mixed feelings during his argument with Boruto. He thinks Boruto has influenced Kawaki, so much so that Kawaki didn't kill Araumi. Buntan and Kyohō visit Kagura's and Hebiichigo's graves, recounting how the conflict ended. Buntan will return to Kirigakure, while Kyohō decides to stay and protect the village. He asks her about Shizuma. She hasn't forgotten her grudge, but no longer wants revenge. Instead, she intends to capture him and make him pay for his crimes. Buntan tells him to take care of their friends' graves. Shikamaru informs Naruto of a follow-up communication from Chōjūrō, which Naruto wishes to inform Boruto about. Chōjūrō informs Ikada they've decided what to do with him and informs him that the Shinonome Project has been halted, in a bid to get proper popular support before developing the nation. This smoothed things over with most Funato supporters, who were against it. However, they're still concerned that someone might want to organise another movement around Ikada, who is the only Funato heir left. Out of gratitude for his decision to stop the conflict, Chōjūrō decided not to imprison Ikada, but instead to put him under surveillance, under Kajiki. Sarada tries to get Boruto and Kawaki to talk to patch things up, but they end up fighting. Sarada is concerned, but Mitsuki and Naruto join her, tell her not to worry and let them fight. They tire themselves out, so Naruto helps them up, deciding to treat them to ramen. He also informs them of Chōjūrō's decision regarding Ikada.
