After the hard-earned funds for their expensive high school class trip are stolen, sophomore Yuichi and his four best friends are kidnapped by Manabu, a surreal character from a creepy late-night anime show. The mischievous Manabu challenges the students to a series of mind games that the five must decipher and outwit in order to win back their trip funds, uncover the thief, and pay off a huge and mysterious debt.
My debt will be reduced by 400,000, 
only 1/5 of the reward for clearing it.
.سيُخفّض ديني بقيمة 400،000، فقط خُمس المكافأة لتبديد الدّين
Dann wird mir nur ein Fünftel der Belohnung,
also 4 Millionen, abgezogen.
a mí solo me restarán
una quinta parte de la recompensa.
a mí solo me restarán
una quinta parte de la recompensa.
Dans ce cas,
ma dette sera à peine diminuée
il mio debito si ridurrà solo di 400.000, cioè 1/5 del premio per la vittoria.
Desse jeito eu vou ter apenas
1/5 da minha dívida liquidada.
Мой долг снизится
лишь на пятую от приза за победу.
