1. Origins of the Mochibato

A few years ago, "strange-looking pigeons" began to be sighted simultaneously in several cities across the country. They had humanoid shapes, puffed-up bodies, and above all—the abnormal trait of showing absolutely no fear of humans.

Initially treated as a new species or a mutation, they spread explosively once the nickname "Mochibato" was coined on social media. Because their cuteness was reported first, warnings about them being "pests" came too late. This history of "information about cuteness spreading before information about danger" symbolizes the essence of the Mochibato problem. Among experts, it is rumored to be the result of urban environments and pigeon populations rapidly "optimizing" for some reason, but no official conclusion has been reached.

2. The "Poppo Charter"—Their Principles of Action

While the Mochibato have no written laws, a consistent "Three Principles" can be observed in the flock's behavior patterns. This is known as the "Poppo Charter."

Article 1: Non-Contention (Fuso). Mochibato never attack first. Even if resisted, they do not fly away; they simply maintain a stance of "not fighting." This "non-resistance" conversely pushes the human trying to drive them away into the role of the aggressor. Article 2: Sharing (Kyoyu). To a Mochibato, human food, space, and time are "shared property" from the start. They have no awareness of stealing; they even think they are just being given their share. Article 3: Status Quo (Genjo). Once a Mochibato has stayed in a place, it changes in their mind into a "land where peace has been established" as a fait accompli. The act of trying to move them becomes, in their logic, the "destruction of peace."

The current theory is that these three principles were not taught by anyone but are a behavioral mode shared spontaneously within the flock. The Mochibato are not lying; they truly believe that if everyone practices this, the world will be at peace.

5. Internal Structure of the Mochibato

While it is said there is no overt leader in the flock, continued observation reveals the existence of "lead individuals" who set the initial mood for the group. When this individual takes a "non-contending" stance, others follow—meaning the brazenness of the Mochibato is not the strong will of a single bird, but is established through the contagion of the atmosphere.

6. Family Structure Oyamochi: The mother of the Mochikko. Gradually becomes more brazen. Mochikko: Oyamochi's children. Chicks. Individuals that only follow behind Oyamochi. They rarely choose locations or make decisions themselves; if Oyamochi moves, they move; if she stays, they stay. Responsibility is always said to lie with Oyamochi, but since Oyamochi herself insists it was a "decision made by everyone," the structure is one where no one actually takes responsibility. When Oyamochi/Mochikko are absent: Another Oyamochi and her chicks will appear from out of nowhere.

In this world, the culling of Oyamochi and Hinamochi is promoted, and extermination tools can be used as necessary. Oyamochi may counterattack when her life is in danger. If the counterattack fails, she may try to use a Hinamochi as a shield.

Furthermore, no one other than the protagonist, Oyamochi, and the Hinamochi should exist in this world.
