Batman Ninja vs. Yakuza League (Japanese:ニンジャバットマン対ヤクザリーグ,Hepburn:Ninja Battoman Tai Yakuza Rīgu) is a 2025animatedsuperhero film directed by Junpei Mizusaki and Shinji Takagi, written byKazuki Nakashima, produced byWarner Bros., and animated by Kamikaze Douga and YamatoWorks, based on theDC Comics characterBatman. It is the sequel toBatman Ninja (2018) and features Batman and his allies fighting to protectGotham City from an invasion ofyakuza-style criminals led by an alternate version of theJustice League.
A day after returning from the past,Batman and his allies discover that the world is not the same as they left it.Japan no longer exists and neither do the heroes of theJustice League. Also, yakuza are raining from the skies. The yakuza belong to Hinomoto, a Japan from a parallel universe, and are using an interdimensional rift aboveGotham City to invade Earth. On Earth, only the people who previously time-traveled can see the rift.
Batman andRobin use the rift to travel to Hinomoto, whileNightwing,Red Hood, andRed Robin stay behind to capture the remaining yakuza. The Bat family are soon ambushed by the Yakuza League, a corrupt counterpart of the missing Justice League and the leading group of the Hagane yakuza clan who took over Hinomoto. The first three Yakuza League members whom the Bat family encounter are Zeshika the Emerald Ray (an alternateJessica Cruz-Green Lantern), the second-in-command Asha the Aqua Dragon (an alternateAquaman), and Bari the Fleet-Footed (an alternateBarry Allen-Flash). The Bat family defends themselves and wards off the Yakuza League with additional help from the Amazone, an opposing Yakuza clan led by Daiana the Eagle Goddess (an alternateWonder Woman).
At Amazone base, Daiana explains the rise of the Hagane clan at Hinomoto; the country consisted solely of yakuza families fighting one another. Recently a clan leader was an alternateDoomsday called Deio Domuzu and was killed by the Yakuza League leader, who is an alternateSuperman called Kuraku. Because the Hagane clan became corrupted and lost the yakuza code of honor called Ninkyou, the Amazone is the only opposing group left. TheHarley Quinn from Batman's timeline is aiding Daiana. She andJoker escaped from prison after hearing the news of yakuza invasions in Gotham.
While departing for Gotham, Batman and Robin are ambushed by Kuraku, and discover that Robin's grandfather,Ra's al Ghul, was responsible for the current reality, having acquiredGorilla Grodd's Quake Engine and upgraded it into the Four-Dimensional Origami System, using it to manipulate parts of Earth's history, creating Hinomoto along with the Yakuza League and ruling it. As Robin is kidnapped by the Hagane clan, Batman is rescued by Joker and Harley, with Joker only rescuing Batman so he can be the one to kill him. However, Joker immediately flees to avoid being killed by Kuraku, while Daiana rescues Harley. Before retreating, Kuraku warns Daiana that the Amazone will be disposed for helping the Bat family.
At Hagane Castle, Ra's reveals to Robin his true plan to use the combined power of both the Yakuza league and the yakuza of Hinomoto to annihilate Gotham and the rest of the world, to remake the Earth in his image. At the Batcave, the rest of the Bat family coordinates the plans to counteract the Yakuza League before returning to the Hagane base, withAlfred Pennyworth providing an anime opening starring them as an inspiration to create "Science Ninja Techniques" against the League.
Meanwhile, the Yakuza League attacks the Amazone base, where both Daiana and Asha recalled their childhood friendships prior to a falling out. The Bat family rescues the Amazone clan and defeats Asha, along with Zeshika and Bari, leaving Batman to personally fight Kuraku before catching up with his allies at the same time Robin escapes from his prison. Having prepared with gear designed against Kryptonians, including a Kryptonite brass knuckle which Superman entrusted to him before he vanished, Batman subdues Kuraku.
When Ra's deactivated the limiters on the Origami System by removing a key, leaving it to exist in multiple dimensions and rendering it untouchable, it causes the Hagane base to appear on Earth and falls to crush Gotham. The Bat family tries to tether the device so they can deactivate it while Daiana fights Ra's to recover the key. However, when the temporal paradox from the Origami System causes both her and the Yakuza League to receive visions of their heroic counterparts, Batman goes to capture Ra's from escaping and retrieves the key to stop the device. The temporal paradox from the engine causes the Yakuza League to reform and transform into Hinomoto's Justice League heroes and follow their counterparts' heroic paths, now joined by a transformed Daiana. When the Bat family finish their parts on shutting down the Origami System thanks to Harley, the Hinomoto-Justice League returns the castle to their timeline and thanks them for everything.
With the timeline fully restored, Batman happily receives calls from the returning Justice League for a weekly meeting. However, to Robin's dismay, a minor setback is that he has a topknot hairstyle from the previous event once again, and he refuses Alfred's offer to have a wig, as wearing it would make him more embarrassed.
