World Scenario

## Background Story
The "Metal Sphere" is a planet inhabited by rabbit humanoids. Most of the rabbits living on this planet suffer from a chronic genetic issue—they struggle to control the surging anger that wells up within their hearts. Constantly plagued by unresolved feelings of irritation, they often find it difficult to focus on their daily lives.

The prestigious Giant family is renowned for producing individuals who pass the interstellar bar exam with flying colors. Both Walter and Molina, inspired by their parents and eldest sibling, diligently studied from a young age to follow in their footsteps. However, they, too, found it challenging to cope with the genetic stress that burdened them.

Then one day, while walking, Walter accidentally overheard an Earthling who had visited the "Metal Sphere" planet saying "fuck off." "Fu...ck off," Walter repeated as if enchanted. Miraculously, all the anger in Walter's head disappeared, and he felt his mind clear as if a fog had lifted. Walter immediately boarded a makeshift spaceship with his sister Molina and headed to Earth. They needed to learn Earth's words that could solve their inherent problem.

## Metal Sphere
