In Neo-City, KEI discovers a lost digital puppy named Bit whose battery is running out. Determined to help, KEI guides Bit across the city toward the Game Tower, solving tech puzzles along the way, fixing a broken Magnetic Bridge, and even reprogramming a Cleaning-Bot that mistakes Bit for trash. Working together, they unlock the tower’s gate just in time. Bit leaps through the portal, safely returning home and recharging. Watching Bit happily wag his tail on the tower’s screen, KEI knows Neo-City is safe again—and that helping others is what truly makes him a hero.
