Life hasn’t been fair to Koyomi. Even though she’s in high school, she’s so short that everyone assumes she’s still in grade school and is teased mercilessly. On the other hand, she’s still better off than Yumiko, who has a magician trying to kill her. Or at least Koyomi was until their paths crossed! Fortunately, salvation arrives in the form of master mage and graduate student Misa Anehara, who agrees to take Koyomi under her wing in learning the new style of magic!
