Misa and Kaho look on as Yumiko attempts to teach Classical Magic to Koyomi. Yumiko becomes highly frustrated when the only things Koyomi can produce are washbasins.
In today's technology-driven society, everything has to move with the times, and magic is no exception. As spells are cast with various magic "codes", made up of binary digits, a computer becomes just as useful to the aspiring mage as a magic wand. One such would-be wizard is Koyomi Morishita, a girl who suffers from a bizarre inability to cast more than one type of spell. No matter how hard she concentrates she can only use code to do one thing: summon metal wash basins, directly above people's heads more often than not! Hoping to improve her versatility, she becomes a student of voluptuous expert witch Misa Anehara. However, with malevolent "daemons" - monsters summoned by unscrupulous magic wielders - appearing at every turn, Koyomi will need all the help she can get!
In the near future, monstrous creatures called “phantoms” descend upon the world. Haruhiko Ichijou is a student at Hosea Academy, along with Mai Kawakami, Reina Izumi, and Koito Minase, three girls who fight these creatures. High school life proceeds as normal until a certain incident reveals the truth of their world to them.
Nodoka and Yue are reading a magic book from the library and come across a spell that shows the red string of fate of a person. One end is attached to the pinky finger of the person it was cast on, and the other end is tied to the pinky finger of their fated partner. Yue casts it on Nodoka and it turns out that the person on the other end of the string is none other than mage-turned-teacher Negi! Though elated at first, much to Nodoka's disappointment it turns out that the spell was just a prank, and the two of them aren't actually fated to be together. Until midnight Nodoka and Negi are stuck together, but Negi still has to take a bath so Nodoka has to tag along. Oh well, perhaps this experience will bring them closer together!
Life isn't always full of magic and battles at the Constant Academy for Magick Arts, and the students know exactly how to kick back and relax – at least, they should. With a simple sports challenge between Hattori and Etou ending up in a naked, magical free-for-all and Teruya causing her normal amount of mischief, it seems that Sai will never manage to find himself a moment of peace.
Meet Chivas Scotch: a sorcerer with a style all his own. The opposite of benevolent and honorable, he's an arrogant and domineering misogynist who travels the lands with his (mostly female) servants, searching for opportunities to indulge his greed and his desire for female flesh. But when he comes across a scheme by a mad wizard to ressurrect an ancient god of darkness, all hell breaks loose as Chivas suddenly finds himself the lesser of two evils!
