The yellowish-brown hamster controlled by the weaver, with the real name "Electric Mouse," was not an adorable creature like Pikachu from Pokémon, but a bloodthirsty monster.
Once, it fully powered up the electricity in a small town in Australia, killing over a hundred people, and, together with its "wife," gnawed the bodies beyond recognition.
Just as they were preparing to eat to their hearts' content and perform a love symphony to reproduce, [The Endless Maze] descended, trapping the last two Electric Mice inside.
The Electric Mouse species originated from an abnormal event, possessing incredibly terrifying reproductive abilities. They rampaged like locusts across Australia in a short period, causing tens of thousands of casualties. The Control Bureau expended vast amounts of manpower and resources to exterminate them, but two Electric Mice managed to escape the purge.
