Kotaro is acting strange. He seems afraid of water which makes him run away, screaming. Even on the follow day, the sight of water still makes Kotaro tremble with fear. This worries Hiro, so with the help of his friends, he decides to investigate.
Jumping into the unknown,
Deeper and deeper
Ein Sprung ins Ungewisse,
tiefer und tiefer.
Lanzándose a lo desconocido
Más profundo
Lanzándose a lo desconocido
Más profundo
Pular em direção ao desconhecido, 
cada vez mais fundo
Я погружаюсь всё глубже в неё.
