Story

After rescuing Mario from the H-corrupted hellscape of Kanto, Luigi decided to take a vacation to the neighboring Johto region. However, he was still unknowingly infected with the H-virus, and it quickly started spreading to the locals. Luigi panicked and fled to Mt. Silver to quarantine himself. As Mario, you will conquer the Johto region, rescue your brother, and destroy the H-virus once and (hopefully) for all!
