Swallowtail

The Swallowtail was first sighted near a certain school. Its form is that of a giant butterfly with vivid colors, composed of numerous paper fragments resembling movie ticket stubs. This makes it rather cumbersome, capable only of low-altitude flight. Despite this, Swallowtail seems to constantly attempt to fly higher, though it has never succeeded. There are many theories about Swallowtail's origin.

The most widely circulated comes from an urban legend: There was once a girl at the school nicknamed "Butterfly." She was introverted and kept to herself, having no friends. Then one day, that quiet and reclusive girl suddenly made a new friend! They skipped classes together for an entire week, and during that time, the two were reportedly always watching movies at the cinema.

Eventually, her parents could no longer tolerate this and locked her in her room, only allowing her out once she promised to stop skipping class. A few days later, when her parents opened the door, they found the window wide open, movie ticket stubs scattered across the empty room, and the girl nowhere to be found… Most of this story has been verified as true, but it seems the girl never had a so-called "new friend".

This new friend is speculated to be connected to the Anomaly's iconic movie ticket stubs: movies that provide viewers with illusions unbounded by reality. For some, a refuge from real life… The girl's life was mundane and unhappy. She was likely easily drawn to the dramatic highs and lows of movie plots, leading her to imagine a new friend who could help her escape reality while also reducing the guilt from her rebellious behavior.

The urban legend is incomplete, and the girl's whereabouts remain unknown. The only certainty is that her habit of collecting ticket stubs and immersing herself in the fictional worlds of movies gave birth to Swallowtail. Swallowtail's constant attempts to fly toward the sky are also believed to stem from the girl's wishes.
