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…
I will wager
my darling's remaining knowledge
سأراهن بمعرفة عزيزي المُتبقّية
Ich setze das gesamte
verbleibende Wissen meines Darlings,
Apuesto todo el conocimiento
de mi cariñito
Apuesto todo el conocimiento
de mi cariñito
Je mettrai les connaissances de darling
en jeu
Metterò in gioco il sapere che
resta al mio tesoruccio
Eu vou apostar o resto do 
conhecimento do meu queridão.
Я рискну оставшимися знаниями милого
