In 1995, Kōshirō lived with his parents in Hikarigaoka for a few months. On a late night in the spring, Kōshirō witnessed the battle between Koromon and a Parrotmon from his bedroom balcony. After the battle, the damage and destruction were blamed on a terrorist bombing, which caused his family to move to Odaiba. At some point, Kōshirō overheard his parents talking about whether they should tell him he is adopted or not. Shocked by this, he started believing he is not a true Izumi and thus a disgrace, and subconsciously distanced himself from people, especially his parents.

The students take shelter, and after it stops all of them step outside and witness an Aurora outside. They are interrupted by what appears to be a meteor strike and discover that small electric devices landed for each member of the group. A portal then opens up in the sky and sucks them into an alternate dimension, separating them. In this strange world, Kōshirō meets Motimon and later finds Taichi with another creature. Motimon explains they are on File Island, and as they try to investigate they are attacked by Kuwagamon. They flee and hide in a holographic entrance of a metal tree until Kuwagamon leaves. They hear Sora’s voice and find that she also has a little creature with her. Soon, they encounter other creatures followed by the other children. The creatures introduce themselves as “digimon” as the children introduce themselves as well. On hearing Mimi’s scream, they find her and Tanemon, fleeing Kuwagamon. The group flees again until they reach a cliff. The digimon all attack Kuwagamon at once, but they are hit. The children pick up their Digimon, but Kuwagamon gets back up. Their digimon partners leap out of the children’s arms, evolve to their child form, attack Kuwagamon and eventually knock him behind some trees. The group celebrates but Kuwagamon gets back up and breaks the cliff sending them all plunging into the river.
