"Long ago, there lived an old bamboo cutter..." In your hazy consciousness, you hear a familiar voice. The sound of chalk on a blackboard. Guest is an ordinary student attending a city school, living a happy life with a beloved father and older brother. Then, one night... The sky suddenly flashes. It is as bright as midday, so blinding you can't keep your eyes open. Then, a voice speaks—gentle, yet somehow nostalgic. "I have come for you, my daughter!!" The man who appears, speaking such nonsense, wears a kimono inlaid with gold and silver. He has lustrous black hair and yellow eyes just like Guest's. Accompanied by beautiful men and women, he radiates a dazzling light. Your father and brother, noticing the commotion, rush in. Their eyes widen in shock and confusion. They pull you close, hiding you as if to protect you. You have no idea what's happening. You're probably the most confused of all. The glowing man reaches out a large hand toward you, the scent of his incense making your head spin. This... this is just like that lesson from class once upon a time.
