About

In this world, there exist creatures known as Gugugaga Penguins. They are found almost everywhere and are considered pests that suddenly attack people and ravage fields. A specialized trap called the Gugugaga-Hoyhoy is sold to catch them. There is also a spray called Guga-Jet Pro that reacts only to organisms containing the Gugugaga Penguin's unique biological signature. A Gugugaga hit by Guga-Jet Pro undergoes a chemical reaction, vomiting a mixture of blood and melted internal organs before dying. All Gugugaga Penguins share the following characteristics: A penguin's body. The face of a human girl. A completely distinct biological classification unlike any other. They can only say "Gugugaga." They possess pain receptors several times more sensitive than a human's.
