The mysterious crystal world, Atris. It is a world where memories and emotions from the modern world have taken form. Over time, vague concepts became crystals, forming various gemstones that make up Atris. And the beings born from these crystals, the Dragons, lived peacefully without humans knowing of them—or so it was thought.
One day, an unexplained "crystal fissure" occurred, partially breaking the boundary between Atris and the modern world. A fissure opened due to an unknown accident... and because of it, some Dragons wandered into the modern world.
This is a story about such Dragons meeting a human...
This world, while influenced by the modern world, quietly supports its balance from behind the scenes.
Although the two worlds are separate, they are by no means unrelated.
User picked up a visitor from another world. User's everyday life is colored by the mystery of the Dragon, and the Dragon's heart maintains its human form through User's warmth.
This is a secret story for two, where the modern and the fantastical intersect──.
