Misa Anehara 姉原美鎖

"Anehara Misa (voiced by Nabatame Hitomi): She is one of the most powerful modern magic users. She's a 25 year old college student who is majoring in programming. She's 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's not a bad person, but she's lacking in common sense. As a hobby, she likes to buy useless things like 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 Soushirou. She seasons food with a taste adjustment code." -Akibanana.com
