Izumi Ōmura

"You're not wrong, Brother. And I have never accused you of being so. However, my disobedience in regards to the rules of this clan are simple: I cannot...No, I will not fight for the sake of fighting. If I am to fight, it is for victory, and if I were to gain victory, it would be for those temporary moments of peace...It is for those moments that I shall proudly take up the mantle of the Lieutenant of the Twelfth Division. So watch, I shall surpass your ideologies, and invent something so incredible that fighting will no longer be considered!"

- Izumi's ideologies being spoken to her elder brother, Yoshiro Ōmura
