Subway: Enemy of the Dimensional Tunnel is the seventh episode of Final Fantasy: Unlimited.
The episode opens with an extremely brief recap of the previous episode's final moments; Bismark dissolves the creatures, and the ground collapses beneath Ai, Yu, Lisa and Chobi.
The group quickly recovers, marveling over how the sand was soft enough to save them from the fall. Below the ground, there is a second desert, but this one does not sport the pillars of fire seen above the ground. The group is surprised to find Kaze has fallen down here as well.
At that moment, Chobi's alarm sounds, and he races off into the distance, claiming a station can be found down here. The group decides to return to the subway, and invite Kaze to come with them. As Lisa touches his hand, he seems shocked, and the scene suddenly cuts to a black and white shot of Kaze and an unidentified girl. Kaze claims "Everything will end in the next fight."
When Kaze opens his eyes, he realizes Yu has led him to board the subway, with the departure bell tolling in the distance. Just as he turns to leave, the door slams such in his face, forcing him to remain on board. As the subway leaves the station, we catch a glimpse of someone watching the group from the next carriage.
Friends and foesEdit
Ai and Yu notice the girl watching them, and enthusiastically chase her, believing she might lead them to the Earl. Lisa chases the children, warning that she may work for the Earl. Lisa yells that the girl is not human, causing all four to come to a stop. Yu greets her, as she shyly hides her face from view.
As she steps out into the open, Ai claims she looks human enough. They share an awkward moment of tension, before Chobi grabs Ai's hair once more. The girl introduces herself as Lou Lupus, or Lou for short, and she quickly overcomes her shyness.
After she explains that she has been traveling the Innerworld for some time, the group invite her to join them, noting it would be helpful to have someone with her knowledge with them. She agrees, but warns them of her "true identity".
Venturing to the front of the train, the children discover that the train was built by Cid, after discovering his mark in the driver's carriage. Suddenly the train seems to panic, and picks up speed. Suddenly a massive claw appears behind the train, quickly gaining on it.
Lou explains that Omega was torn to pieces a while ago, and what is chasing them is Omega's nail. She goes on to describe how Omega destroyed her world, and everything she loved. She claims that despite the destruction of the beast, Omega still lives, though she is unsure how.
As the back carriage breaks away, the group comes face to face with Omega, and share a moment of awe and panic over its shear destructive power. After remembering the destruction of her world, Lou requests a mirror. PoshePocket obliges, producing a mirror easily taller then Lou, and several times larger then itself.
Lou stares at her reflection for a moment, when suddenly her eyes begin to glow, and she transforms into a werewolf. Taking her place atop the subway, she releases a huge energy blast at Omega. Kaze, seeing this, remembers he's seen a light similar to this before, revealing the girl from his memory to be someone named 'Aura'. It is revealed that Lou's attack has no effect on Omega, whatsoever. It shrugs her off with an energy blast, sending her tumbling into the unknown. The others question Kaze as to why he let her fight alone, with Lisa going as far as to claim that though Lou was a werewolf, she was more human them him.
Inspired by this, Kaze primes the Magun, and prepares to fire. The group watches in awe as Ifrit charges at Omega, but quickly panic when Ifrit's first attack seems to have no effect. Kaze calms them, telling them Ifrit will never lose, regardless of who he is fighting. This is confirmed when Ifrit charges in, using itself as a final attack, causing Omega to shatter.
As the group recovers, they notice the final carriage returning, with Lou inside. After noting the Kaze is once more missing, Ai wonders if they will meet again, but Yu claims that Kaze will return, like he always does. The episode closes with Lou mentioning that despite everything, Omega has not been destroyed, and will return.
Kaze reveals another Soil combination in this episode:
The grinding teeth of incandescence/The flaming hot fang - Cardinal Red
The gale of red lotus flowers/The deep blood of the hurricane - Dark Crimson
The strength of steel - Burnt Sienna
This summons Ifrit, whose flames can stop anything in its tracks.
