Wonderland: Journey into the Darkness is the first episode of Final Fantasy: Unlimited.
Final Fantasy: Unlimited begins on a dark Japanese night at a dock town. A dock worker is annoyed when his radio broadcast fades to static, moments later a strange black pillar appears on the horizon, stretching into the sky. While science labs nearby are thrown into chaos by the strange appearance, the rest of the town freezes to watch.
Two such scientists observe the pillar from a balcony; Joe and the pregnant Marie Hayakawa. There is a sudden flash of light and the pillar branches off with a small appendage. A red dragon appears a few seconds later, hovering nearby.
The navy and the air force arrive to destroy this threat, but the fleets are destroyed in moments. It is then a second appendage and a second dragon appear, white this time. The two dragons engage and destroy each other.
Several years later, the town seems to have continued despite the destruction faced at the appearance of the pillar, which still stands off the coast.
Two children are seen exploring an abandoned subway station, discussing rumors of subway workers' disappearances; they sit and wait for a train in the ruined station, and it's revealed they are looking for their parents. They're amazed when a bizarre looking train appears and its doors open for them; after a moment's hesitation, they board it. Just before it departs, a dark figure can be seen boarding further down. The train speeds off, vanishing in a flash of light; inside, it is empty of people, and not a sound but the engine can be heard.
In the car behind the children a female hiding in the shadows attempts to report to someone, but doesn't seem to get a response; as she attempts to regain the signal, she's noticed by the girl, who calls out to the boy. While the girl remains suspicious of this woman, the boy explains they're following their parents in an attempt to find them. Reaching into his bag, he draws out a book on Wonderland with Joe and Marie on the cover; stating that his parents wrote this book, he introduces himself as Yu Hayakawa; the girl is his sister, Ai. The woman gives her name as Lisa.
Ai continues expressing her misgivings about Lisa, but the train suddenly begins shaking violently. When the train finally stops they discover it's parked vertically in a strange station consisting of a spiral staircase and four support pillars. As they disembark and climb to the surface, Lisa avoids answering why she's in Wonderland in the first place.
The children emerge in what appears to be a city of some kind, but devoid of people once more; after briefly scouting around they find everything to be made of plants and bugs, with man-sized bugs living within the buildings. As Yu searches he comes across an ostrich-sized yellow bird which he attempts to befriend with a chocolate bar, but when Ai turns up it attempts to eat her hair instead. After shaking Ai around and dazing her the bird flees; Yu gives chase, recalling an entry for it in their parents' book. As he does so, he comes face to face with a man dressed in black, bound to a wall by roots. Ai and Lisa catch up to Yu, and the man slowly opens his eyes, asking where he is, and reveals he's searching searching for someone, but has forgotten his name....
Before they get any further, a strange, blimp-like ship appears in the sky and begins dropping bombs on them. Rather than exploding, the bomb releases a mushroom-esque creature that attacks Lisa and the children, though Lisa is able to stop the giant creature's blows and send it flying with seeming ease. She describes this as her Kigen Arts, similar to a martial art, but the creature rises again, this time larger, before she can give any more details. Lisa claims it's to large for her to defeat, and they run for it, the monster hard on their heels.
Just as it seems the monster's about to kill them, the man in black reappears. Revealing a strange golden tube covering one arm, he calls out "Soil is my power," causing the tube to sprout four turbine fan blades, then reassemble itself into a three-barreled gun with a beating black heart at its core. This, he calls the Magun.
Loading three bullets into the gun, he aims and fires. A cloud of smoke erupts from the barrel, followed shortly after by three shafts of light which spiral towards the creature. It attempts to block them with one fist, but the creature's body begins to twist and distort until fire erupts from within it, and a fiery bird emerges from its ashes.
As the group admires the man's power, another strangely dressed man watches from afar. He utters a single word: "Unlimited."
The Soil and Magun are introduced in this episode, with the first combination used being:
- Origin of all /The origin of all things - Mother Black
- Burning all to ashes /A heat that will scorch all creation - Fire Red
- The critical point of all/The critical point of everything - Burning Gold
This summons Phoenix; a fiery bird that enters the target's body then explodes in a brilliant flash of fire.
