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.
It was just the only choice 
that would let me survive.
إنّما كان ذلك الخيار الوحيد الذي يُنجّيني
Es war nur der einzige Weg,
um zu überleben.
Simplemente era lo único
que podía hacer para sobrevivir.
Simplemente era lo único
que podía hacer para sobrevivir.
C’est seulement que j’avais pas
d’autre choix pour survivre.
Era solo l'unica alternativa
che mi avrebbe permesso di sopravvivere.
Era apenas a única escolha 
que me permitiria sobreviver.
Просто... только таким образом 
я и мог выжить.
