Seiichi and Airi are sent to the world of the dead by Demioros' Deliverance and have to search for the Gate of the Living and overcome its trials in order to return to life.
It wasn't love at first sight 
because she gradually became
Es war nicht Liebe auf den ersten Blick,
aber durch die Gespräche auf dem Dach
Gracias a sus charlas,
tu amabilidad fue atrayéndola,
Gracias a vuestras charlas,
tu amabilidad fue atrayéndola,
C’était pas un coup de foudre.
Mais au fil de vos discussions
Non è stato amore a prima vista
perché la tua gentilezza
Não foi amor à primeira vista
porque aos poucos ela se tornou
Это была вовсе не любовь 
с первого взгляда.
