The Battle of Hi City

A war had broken out between the residents of Hi City. The reason was that the maintenance office stopped supplying water to the residents. Giant went crazy and beat up everyone in his way, leading to the The Battle of Hi City. Everyone who waned to survive was participating. The people who were sick of their lives were just standing there waiting to be killed.

Doraemon asked, "Why are you fighting with each other? Shouldn't you be fighting with the guys from maintenance office?", Everyone said, "You're right!", and went off to the maintenance office. It seemed every last guy from the maintenance office already fled for their lives. 'Natural reaction', everyone thought. They sighed, this was going to be one hard battle.
