"The Mobile Fortress" (移動要塞, Idō Yōsai) is episode 237 of the Boruto: Naruto Next Generations anime.
Synopsis[]
Buntan takes their discovery as confirmation of the rumours she'd heard about the Funato. Boruto wants to inform Kagura, certain the fortress should have a way to make contact. Iwabee informs the others there are no ships pursuing them and the freed hostages. Sarada radios Kagura of their rescue of the hostages, telling him they should arrive at the rendezvous as planned. He in turn reveals the existence of the mobile fortress, and that he sent Boruto and two others to investigate. Boruto manages to contact Kagura, and they update each other. He reveals the fortress is moving toward the rendezvous point, and that if Sarada's ship is spotted, it'll be obliterated by the fortress' scientific ninja tool. They're finding difficult to do much with so many Funato aboard. The Funato boat they came across earlier catches up with Kagura's boat, ramming through it. Boruto decides they have to destroy the fortress' weapon themselves. Kagura wants to use Taiki's damaged boat as a distraction to help Boruto. Taiki's boat collides with the fortress, and the Funato are ordered to check on it, giving Boruto and the others a chance to get closer to the weapon. They're spotted by two guards. Buntan takes one out with a Lightning Ball, but the other escapes to call reinforcements. They wonder how to destroy such a big weapon, and Kawaki suggests destroying the door to buy themselves time. Kagura arrives with Hebiichigo and Kyohō, having defeated the remaining guard, Hebiichigo sewing the door shut behind them. Buntan thought Kagura would only order them around instead of taking part of the action. Kagura informs them they've lost Taiki's boat, and can no longer contact Sarada and Mitsuki. Before they can decide on how to attack the weapon, Tenma arrives, and is disappoint to see only children. Hebiichigo attacks, but Tenma summons a fiddler crab pincer and counterattacks. The sight of Hebiichigo's blood triggers Kyohō into a rage, and he begins pressuring Tenma. His attacks with Kabutowari destabilise the fortress' structure, drawing Boruto's attention to a way they can get on top of the weapon. Kyohō also attacks Boruto and Kawaki, Buntan warning them of Kyohō's rage. Tenma uses the opportunity to attack them as well. Kagura knocks Kyohō out and takes up the fight with Tenma, Hebiichigo looking after Kyohō. Tenma is notified of a ship that contacted them from Dotō Island, and figuring it's Boruto's allies, orders to get on firing range. Kagura fights Tenma, and protects Buntan when Tenma shifts his focus to her. Kawaki joins Kagura against Tenma. Boruto reaches the chakra cannon, just as it takes aim at the ship and begins charging up. Iwabee spots the fortress aiming at them in time for Denki to change course and dodge the shot. Tenma is informed they missed, and orders to fire it again. Buntan holds off the guards while Boruto uses a maintenance crane to drag the cannon around as it fires, damaging the fortress. Kawaki and Kagura hold Tenma down and prevent him from stopping the shot in time. The fortress begins to collapse, so Boruto, Kagura, and the others escape. Tenma vows to kill them. At the ship, Team 5, Sarada, and Mitsuki are relieved. They all join up at the ship and thank each other. Team 5 is surprised by the presence of the swordsmen. who celebrate reduced sentences with the mission's success. Kagura wants everyone back home safely, so he orders Taiki to take them back to Kirigakure first.
