Kiyoshiro visits a shrine in Kyoto on a school trip. From then, someone starts to come pick Kiyoshiro up at night and challenges his knowledge. He then slowly starts forgetting things he should know…
Jumping into the unknown,
Deeper and deeper
Ein Sprung ins Ungewisse,
tiefer und tiefer.
Lanzándose a lo desconocido
Más profundo
tobikomu mitaiken no oku no oku ni
Pular em direção ao desconhecido, 
cada vez mais fundo
Я погружаюсь всё глубже в неё.
