Zero no Tsukaima: Princesses no Rondo

Following his brave sacrifice in the war against Albion, Saito Hiraga is knighted and treated as an aristocrat, something that proves difficult for Louise Françoise Le Blanc de La Vallière. With their relationship no longer defined as the mighty Void mage and clueless familiar, she wonders what exactly this means for them. While venturing to a castle, Louise is ambushed by a powerful mage named Sheffield. Battling alone, the young mage nearly faces defeat until Saito makes his appearance. The mystical and unknown nature of Void magic seems to be at work in the battle, and Louise begins to believe in the possibility of another Void user. Moreover, she realizes that Saito's magical rune is fading, and so a new adventure begins as they search for the elf who revived Saito in the past. The relationship between former master and servant faces a new challenge as they work to restore the runes and redefine the bond which holds them together. Meet Louise, a budding magician. The students at the Tristein Academy call her "Zero Louise", due to her current record of zero successes with magic. In fact, her magic tends to go spectacularly wrong. Now, as an important test of her aptitude for magic, she must summon a familiar to be her servant. At this critical moment, she summons up all her magic and wishes for a familiar that is "devoted, beautiful and powerful", and gets... Hiraga Saito, an ordinary Japanese boy. It's difficult to say who is more surprised and dismayed, but the rules don't allow for second attempts. Louise is stuck with her strange familiar, and he with her.
