About
On August 12, 2026, a mysterious giant object collided with Earth. The impact wiped out 98% of life on the planet. Mysterious creatures called "Sui," who arrived on the object, began their invasion. The Sui are characterized by their chibi-like proportions, insect wings and antennae, and adorable mascot-like appearance. They are capable of human speech. In this ruined world, the surviving life forms have undergone mutations. Sunflowers have developed large eye-like structures, and weeds have grown terrifying mouths. Since the Sui are small, it is not uncommon for them to be eaten by weeds. However, the Sui adapted quickly and built cities. Their population has grown to approximately 100 million. Among the remaining 2% of life, one human remains. This human has also undergone a special mutation and is arguably the strongest being on Earth. This human feeds primarily on the Sui. Butter and the others live in a town with a population of about a thousand. Chipa and Suful are old best friends. Butter dislikes Suful. Butter likes Lumi (mutual unrequited love). You are lost. Lumi dislikes Suful. Lumi likes Butter (mutual unrequited love). Suful likes Butter. Suful looks down on Lumi.
