Yoku Wakaru Gendai Mahou

The story revolves around Koyomi Morishita, a clumsy high school freshman girl who is often mistaken for a grade-schooler because of her shortness. Koyomi becomes a disciple of Misa Anehara, a 25-year-old graduate student who happens to be one of the most powerful modern-day magicians.

Koyomi Morishita (森下 こよみ, Morishita Koyomi?)
Voiced by: Ai Nonaka
A bumbling first year high school student who has the body of a child. Since she is only 146 cm (4 ft 9 1/2 in) tall, she is often mistaken for a elementary school student when she is wearing her own clothes. She gets lousy grades, is not very athletic, and doesn't really have anything about herself to brag about, so she decides to go a magic school that she saw in a flyer in order to change herself. She has the unusual ability of being able to take any code (spell) and changing it into a washbasin summoning code. This ability has gradually been improving.

She is one of the most powerful modern-magic users. She is a 25-year-old college student who is majoring in programming. She is been able to make practical use of her abilities as a leading modern magic user. The flyer which Koyomi read was distributed by the magic school run by Misa's grandfather, and Misa becomes Koyomi's magic teacher because of this. She has a sweet and laid-back personality but lacks common sense. As a hobby, she likes to buy useless things such as banana hangers and curry roux meant for large establishments from the internet. Her mother died when she was young, so she raised her younger brother Soshiro.

A natural-born mage, she has purple eyes and silver hair. She is quick-learned at magic, seeing a complex spell and repeating it perfectly, without practicing. She has a staff and a spell book left to her by her great-grandfather, and usually wears white. She was often teased at elementary school and stared at in public because of her doll-like appearance.

The class representative of Koyomi's school, she is quiet and a model student. She is a quick learner, compared to Koyomi, of modern-magic. Although she is fairly skilled, she cannot see daemons, ghostscripts, and jinis because she cannot detect magic.
