Nezumi, Warrior of the Rat, is an ordinary high school student in his normal life. He used his ability, Hundred Paths of Nezumi-san, to become the Taisen's lone survivor, and in the process learned the wishes of the battle's other participants. When Duodecuple reappears and prompts him for his answer, Nezumi does as Ox taught him, and offers the one answer that is right for him.
When you get to my age, you learn 
that youth is the real treasure.
عندما تصبح بمثل سنّي، ستدرك أنّ الشّباب
هو الكنزُ الحقيقيّ
Wenn du so alt wirst wie ich,
weißt du, was die Jugend für ein Schatz ist.
A mi edad descubres
que la juventud es un verdadero tesoro.
A mi edad descubres
que la juventud es un verdadero tesoro.
À mon âge, on est conscient
qu’il n’y a rien de plus précieux.
Quando si arriva alla mia età,
si capisce che il vero tesoro è la giovinezza.
Quando se chega à minha idade, você aprende
 que a juventude é o verdadeiro tesouro.
Доживёшь до моих лет, узнаешь, 
в чём ценность юности.
