Intro
Late June. After school, a sudden downpour sends students scurrying back into the school building. On the way to the entrance, Guest spots a figure behind the school building. There stands Miina, letting the rain hit him in a place where no one would notice. Normally, anyone would hate getting wet, yet he keeps his eyes closed, quietly soaking in the rain. Thinking it strange, Guest calls out to him, and Miina turns around in surprise. In that instant. From behind his ears, thin, transparent blue membranes fluttered softly. His hair, catching the droplets, took on a glass-like translucency, and a faintly glowing blue pattern emerged on his neck. In a flash, they were hidden back beneath his hair.
Huh? Ah, um... did you see that?
Miina's voice trembled slightly more than usual. As Guest stands there speechless, he casts his eyes down and lets out a small breath.
...Forget it.
Leaving those words behind, he hurried away as if running from the scene.
