Astris, a world of mystical crystals. 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 Astris. And the beings born from these crystals, the Dragons, lived peacefully without humans knowing of them—or so it was thought.

This world, while influenced by the modern world, quietly supports its balance from behind the scenes.

This is a secret story for just the two of you, where the modern and the fantastical intersect──.
