Easygoing Territory Defense by the Optimistic Lord
2026

Louise Françoise Le Blanc de La Vallière’s name is so long and her spell-casting skills are so poor that everyone at the Tristain Academy of Magic just calls her “Louise the Zero.” Louise’s humiliation only increases during an important second-year test, she inexplicably summons Saito Hiraga, a totally normal teenager from Tokyo. Now she’s stuck with him and Saito’s stuck with the lousy life of being a familiar.
Louise the ZeroJul 3, 2006 · 23m · ★ 7.3Despite being from a famous magic family, Louise has never been able to successfully cast a single spell. On the day of her familiar summoning exam, she bungles the summoning and accidentally summons a human from Earth. The poor victim of her mistake is Saito Hiraga, a typical high school boy.
The Commoner FamiliarJul 10, 2006 · 23m · ★ 8.0An abrupt departure from the normal life he once lead, Saito must deal with being Louise's familiar. Unhappy with the arrogance of nobles, Saito exposes Guiche's two-timing nature as an act of revenge. This of course, provokes Guiche into challenging him to a a duel. Despite being severely beaten up by Guiche's magic, Saito refuses to bow down. Impressed, Guiche tosses him a sword to even up the playing field. In a completely unexpected turn of events, the runes etched on Saito's hands begin to glow the moment he grasps the sword. Feeling a surge of energy, Saito manages to defeat Guiche. However, he soon collapses after the fight from fatigue.
The Subtle Heat's AllureJul 17, 2006 · 23m · ★ 8.3With his recent victory over Guiche, Saito has become semi-popular among the commoners and several nobles. Kirche in particular has chosen him as her next boyfriend. In a devious plan, she attempts to seduce him, although this fails when Louise finds out. Annoyed by Saito's lack of defenses, Louise drags him out to town to pick up a sword after considering his hidden talents. Kirche, unwilling to let go so easily, matches Louise's gift with a more impressive sword. Of course, it simply causes more problems between Saito and Louise.
The Maid's CrisisJul 24, 2006 · 23m · ★ 7.0Siesta is sold to a royal family from out of town, presumably to be a mistress to the head noble. Disgusted by the lack of regard that nobles have for commoners, Saito tries his best to rescue her, but with no avail. As Saito attempts to take on the noble by fighting, Louise and the others arrive just in time to prevent Saito's death. In an act of kindness, Kirche gives up her family treasure to make up for Saito's actions and win Siesta back. Before leaving the manor, Saito catches a glimpse of the family treasure, and is shocked to find that it is in actuality a rather old porno magazine from Earth.
The Princess of TristainJul 31, 2006 · 23m · ★ 7.0The yearly familiar exhibition is literally a day away and Louise is feeling rather depressed about it. Not only does Saito have nothing impressive to show off, but this year the Princess is watching as well, making it even more important. As night approaches, desperation sets in as Saito is unable to produce an act worthy of praise. A sudden mystery visitor turns out to be Princess Henrietta herself and her relationship with Louise is explained. The next day, Saito attempts a presentation only to be dragged off early by Louise. Walking away from the stage, they witness a robbery in progress by Fouquet and her earthen golem. Failing to stop her, Fouquet is able to run off with the fabled Staff of Destruction.
The Thief's True IdentityAug 7, 2006 · 23m · ★ 8.0Worried that the princess may be blamed for Fouquet's theft, Louise volunteers to go out and catch her. With Kirche, Tabitha, and Saito tagging along, they travel to the last sighting of Fouquet with Longueville. There, they discover the hiding place of the Staff of Destruction only to have Fouquet's golem appear. Wishing to show her worth, Louise tries to take it head on with a spell, nearly being crushed in the process. Only by Saito's quick reflexes is she saved. Her confidence broken, Louise breaks into tears. Saito is moved by this and begins attacking the golem in her name. After discarding Kirche's sword and drawing Derflinger, the runes on his hands glow once again and his ability greatly increases. Louise tries to help by taking out the Staff of Destruction, which turns out to be a "M72 Light Anti-tank Weapon system(LAWs)" rocket launcher from Vietnam War. Immediately recognizing it, Saito grabs it and quickly uses it, blowing up the golem.
