Yuzo the Biggest Battle in Tokyo

In the year 2020, the world is threatened by a new coronavirus. The impact of the virus is not only on health but also on the economy, and Yuzo Oki, who was enjoying his remote life, is easily laid off.

Somehow, he manages to find a new job, but what awaited him was a crazy group of people, including a money-grubbing president, a fitness instructor with no members, a garbage thief who only collects waste, a gambling salesman, and a man who stays inside a stuffed animal. However, after being pushed around by these selfish people, he gets desperate when he is dumped by his girlfriend.

Just then, a lifeform from outer space comes into contact with Yuzo's crazy co-workers and fuses with their madness, creating an explosion of energy that plunges the city into chaos. The only person who can save the city from this crisis is Yuzo. Having been thrown into the depths of disappointment, he now rises to the occasion.
