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.
I've never thought about a reason 
for fighting, a reason for living!
لم أفكِّر في سببٍ للقتال أو في سببٍ للعيش
Ich hab mir nie Gedanken gemacht,
wofür ich kämpfe oder lebe …
¡Nunca he pensado en una razón
para luchar o para vivir!
¡Nunca he pensado en una razón
para luchar o para vivir!
j’ai jamais réfléchi à pourquoi
je me battais ou je vivais !
Non ho mai pensato a un motivo
per combattere, o per vivere!
Nunca pensei num motivo
 pra lutar ou pra viver!
Я никогда не думал о причинах 
для сражения, да и для жизни!
