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 can't leave until
I steal one piece of knowledge!
لا أستطيع المغادرة ما لم أسرق 
!قطعة معرفة واحدة
Ich gehe nicht, bis ich dir nicht
ein Stück deines Wissens gestohlen habe!
Eu não posso partir até roubar 
um pedaço de conhecimento!
