Quotes

 * (To his comrades) "That's right!! The chairman is using peace as an excuse to avoid waking the hero up because he's afraid!! Most of the townspeople respect the decision of the chairman!! But we who disagree with him have gathered to wake up the hero!! Their idea of peace and coexistence is just an illusion!! We don't want fake peace!! Now that the wall's defenses are weaker, this is our chance!! We're gonna wake the hero up and beat those enemies outside even if we die trying!! Today, we're gonna be the 'heroes' who wake the 'hero' up!!"
