Digimon Tamers: Runaway Locomon 2002

Six months after the D-Reaper’s destruction, the Tamers plan a surprise birthday party for Rika, who learns of the surprise and is displeased. An out-of-control train-Digimon, Locomon, appears and wreaks havoc as it races around the tracks. Takato [Makoto Tsumura] has Guilmon [Masako Nozawa] digivolve into Growlmon to stop the train, but the move falls short. Takato, Rika, and Renamon [Yuka Imai] manage to board Locomon to find a way to slow it down, while the remaining Tamers, except for Suzie, board a freight train to catch up to Locomon.

Mitsuo Yamaki [Susumu Chiba] takes command of the rail centre and realizes that Locomon’s path is creating a distortion in the digital field that is expanding into the real world. He directs the rail workers to manually divert the tracks to redirect Locomon back to the Digital World, trying to restore the balance between the two realms.

On board Locomon, Rika falls under the train’s control and attacks Takato as she has a vision of her estranged father. Takato discovers that Rika and Locomon are under the influence of Parasimon. He and Guilmon biomerge into Gallantmon and destroy Parasimon to free Rika, but Parasimon manages to send out a signal to begin an invasion of the human world.

Gallantmon, MegaGargomon, Sakuyamon, Justimon [Jun’ichi Kanemaru], Guardromon, MarineAngemon [Ai Iwamura] and Beelzemon Blast Mode fight back against Parasimon, but they are outnumbered. Gallantmon’s determination allows them to evolve into Gallantmon Crimson Mode, granting the group the power to destroy all Parasimon at once. Locomon returns to the Digital World, and the threat to both worlds seems to recede for the moment.

All the Tamers attend Rika’s birthday party. When Kazu asks Rika to sing since she had been singing a song while under Parasimon’s control, she leaves the party. As she watches the sunset, she sings the last line of her song in her head: “You promised me we’d stay for the sunset.”

You promised me we’d stay for the sunset
