All Aboard

Summary
Takuya Kanbara is getting ready for his brother's birthday party. He’s very bored and about ready to do anything rather than sit there. He receives a phone message from Ophanimon, follows the directions she gives, and finally ends up at the subway station. He gets in an elevator after seeing Koji Minamoto. He tries talking to him but fails in getting an answer. He finds three other children on the train he chooses after it almost sped away without him. Luckily, he caught on to the back, before seeing Koji on a train beside his, riding away into another tunnel.

The three other kids Takuya meets are J.P. Shibayama, Zoe Orimoto and Tommy Himi. J.P. and Zoe have apparently also received a message on their cell phone, just as Takuya did, with the exception of Tommy, who was bullied by two boys on to the train. The four children begin to talk, but then, all of their cell phones transform into D-Tector Digivices.

A bit later, they realize the train they boarded is not just an ordinary train; it is a Trailmon! They find themselves in the Digital World, confused. The four children get off of the train, being rudely greeted by a herd of Pagumon. Trailmon tells the Digi-destineds that, in order to get home, they need to find a Spirit. Tommy becomes scared and runs across a metallic bar that bridges a canyon, but he slips. He is grasping on for dear life.

All of a sudden, two odd Digimon, Bokomon and Neemon, come running from a greenish glow. Cerberumon appears using his Emerald Blaze. The three-headed black canine then attacks the kids. Takuya, along with Bokomon and Neemon rescue Tommy while Cerberumon attempts to attack them. Amazingly, Takuya finds the Human Spirit of Flame, and Spirit evolves with his D-Tector into Agunimon. The battle rages on. Cerberumon uses his Portal of Darkness attack and traps Agunimon in the dark area. Agunimon uses his Pyro Tornado attack to finish off Cerberumon. Takuya then dedigivolves back to his original state, leaving the children dazed and confused.
