With his victory over Guiche, Saito has become popular among commoners and several nobles. Siesta and the commoners give Saito leftovers since he is starving under Louise's treatment while calling him "Our Sword". He also learns why the peers call her the "Zero". To add to his troubles Kirche, a noble from Germania, has chosen him as her next boyfriend. In a devious plan, she attempts to seduce him, although this fails when Louise finds out. After considering Saito's hidden talent, Louise drags him to town to buy a sword. Kirche matches Louise's gift with a more impressive sword, which causes more conflict between Saito and Louise. Louise's sword later reveals itself to be the talking sword Derflinger. (Source: Wikipedia)
