In the year of 20XX, a young boy by the name of Netto Hikari receives a very special gift as he enters the 5th grade. His very own customized net navi, Rockman! Despite Rockman's small size and far more responsible personality, the two boys quickly become the best of friends. A net navi is designed to guide his operator from the inside of his or her PErsonal Terminal, or simply PET for short. Children and adults alike enjoy friendly "Net Battles", where they spar their navis against each other to prove their worth.

Netto's father Yuuichirou Hikari has made a scientific breakthrough by introducing the "synchro chips". If an operator and his or her navi are in a special enviroment known as a "dimensional area", they can fuse together in the real world via a technique called "cross fusion"! Yuuichirou's first test subject, Misaki Gorou, attempts the process and sadly fails. Netto offers to try with Rockman, but his father forbids it. Cross Fusion puts enormous strain on the operator's health, and battling in the real world could mean death.

Deep in the dark recesses of the UnderNet, Forte sleeps as he drifts aimlessly. In this cybernetic graveyard, a pulsating power re-awakens Forte, alerting him to a dangerous being shortly ahead. A haunting face appears amidst a massive bright purple blob, laughing directly at Forte. Cursing him, Forte finds himself powerless as the blob takes form, and captures him within its grasp!

Nearing the time of sunset, a peaceful city and its people go about their everyday business. Curious bystanders on a sidewalk glimpse a shimmering purple light, which suddenly expands into a tall pillar that reaches up to the sky. Screams erupt from the people as the pillar of light takes flight, absorbing everything in its destructive path. A tower clock dings the hour of 4 o'clock as the pillar disintegrates, leaving behind a trail of cybernetic residue and utter emptiness.
