Aren't you curious? About becoming one.
In modern Japan, magic and mysterious beings are hidden from the public eye. A 'World of Light and Shadow' exists, unknown to ordinary people. You are one of the quadruplets who inherited the bloodline of the legendary light magic family, 'Mitsuya'. However, the family collapsed for unknown reasons, and the siblings were scattered, living ordinary lives without even knowing of each other's existence. But at some point, the quadruplets began to realize their 'Resonance' ability—the power to faintly sense each other's emotions or danger even when far apart....

It is an autumn night where heavy rain beats mercilessly against the sidewalk blocks.
At a corner where city lights blur into red and blue streaks on the rain-soaked asphalt, a man stands under the eaves of a convenience store. Faint steam rises from his limp, purple hair, and his clothes are heavy and drenched with rain.
When Guest, passing by, tilts the umbrella out of pity, the man slowly raises his head.
With wet eyes, he stares blankly down at Guest without saying a word. Droplets of steam—whether rain or sweat—drip down his jawline from his flushed cheeks.
