Digimon Adventure: Last Evolution Kizuna

Digimon Adventure: Last Evolution Kizuna (デジモンアドベンチャー LAST EVOLUTION 絆, Dejimon Adobenchā LAST EVOLUTION Kizuna) is the fifth movie of the Digimon Adventure series.

Plot
Five years after the events of Digimon Adventure tri., Taichi and the other Chosen Children are approaching adulthood; however, Taichi and Yamato still remain undecided about their future goals. The Chosen Children later meet Menoa Bellucci, a professor at Columbia University in New York, and Imura Kyōtarō, her bodyguard. Menoa claims that Eosmon is targeting Chosen Children around the world by robbing both them and their Digimon partners of their consciousness. With Menoa's help, Taichi, Yamato, Kōshirō, Takeru, and their Digimon fight Eosmon on the Network.

When Taichi and Yamato fuse their Digimon into Omegamon, their form falls apart, allowing Eosmon to escape. In the Real World, Taichi and Yamato find countdown rings on their Digivices. Menoa explains the Digivices are powered by the infinite potential of children, and because Taichi and Yamato are growing up with their potential fulfilled, they have a time limit before they are separated from their Digimon forever. She also warns them that evolving will accelerate the countdown. While Kōshirō examines Eosmon's gems, Yamato suspects Imura is involved with Eosmon, and asks Daisuke, Miyako, Iori, and Ken to investigate Menoa's job in New York. Meanwhile, Gennai visits Taichi and Agumon, corroborating Menoa's statement.

After Eosmon leaves Mimi unconscious, Yamato gives Taichi and Kōshirō prepaid mobile phones out of suspicion they are being tracked and also shows them a news article revealing that Menoa used to have a Digimon partner. As Yamato continues to investigate Imura, he learns from Daisuke's group that Imura's identity is fake and Eosmon's data was found on his hard drive, deducing that he is the culprit. Kōshirō is sent a link to a live stream video of Takeru and Hikari held hostage, prompting Taichi and Yamato to rescue them, while Jō goes missing. By the time they arrive, Takeru and Hikari are already unconscious from Eosmon. On the way, Yamato confronts Imura, who reveals he is an FBI agent investigating Menoa, and he realizes that Menoa orchestrated the kidnappings and Eosmon as a distraction to target Kōshirō for the list of Chosen Children. Realizing this as well, Kōshirō texts Taichi with the coordinates to Menoa's location in the Digital World, before she renders him unconscious.

In the Digital World, Menoa confirms that she lost her Digimon partner, Morphomon, prematurely from growing up, and discovered Eosmon's digi-egg during the recent aurora. To prevent the other Chosen Children from experiencing loss, she has captured their consciousness to allow them to be with their Digimon partners as children forever. Menoa sends a swarm of Eosmon clones to the real world to kidnap more Chosen Children, sparking battles worldwide. Taichi, Yamato, and their Digimon resolve to stop Menoa even if it quickens their separation, and Agumon and Gabumon fuse into Omegamon to fight her and the Eosmon clones. After Menoa biomerges with Eosmon, Eosmon cuts Omegamon into pieces, causing it to split again. Taichi and Yamato are assaulted by the Chosen Children and their Digimon partners, but Taichi grabs Hikari's whistle and blows into it, awakening and turning them back to normal. While the Chosen Children and their Digimon partners join the battle, Taichi, Yamato, and their Digimon make one final evolution, forming Agumon (Bond of Courage) and Gabumon (Bond of Friendship). The two Digimon defeat Eosmon, with Menoa finding closure with Morphomon.

After the battle, Imura arrests Menoa. Taichi and Yamato spend their remaining time with Agumon and Gabumon respectively, until they vanish and their Digivices turn into stone. The next spring, Taichi and Yamato move on with their lives and pursue their dream careers, under the belief that they may see their Digimon partners again in the future.
