Misaka Misuzu

Misaka Mikoto's mother, first appeared in volume 9 and again in volumes 10, SS1 and SS2. Currently studying at a university. Mikoto often comments her mother acts more like a child than she herself is. Misuzu is very weak to alcohol, and after getting drunk she has a habit of clinging to a young guy she finds attractive, as Touma and Accelerator found in SS1, when she got drunk and clung onto Accelerator, who called a taxi to take her to a accomadation. Touma ran into her when she refused to get into the taxi and ended up exchanging phone numbers

In SS1 she, along with many other parents, want to take their children home due to the worsening political situation after Vent's attack on Academy City. The Board of Directors does not want that since the children are valuable test subjects and in worse case scenario valuable military assets for the city. The Directors then hired Skill-Out to eliminate her, offering amnesty to Skill-Out if they succeed, but Skill-Out was stopped by Touma and Accelerator. Misuzu then said before leaving if there are people like Touma and Accelerator in the city to protect Mikoto then she feels better for leaving Mikoto in Academy City.

In SS2 it turns out she and Kamijou Shiina, Touma's mother, are friends after meeting in Daihasei Festival.
