Misaka Misuzu

Misuzu Misaka is Misaka Mikoto's mother and wife of Misaka Tabikake, first appeared in volume 9 and again in volume 10, Volume SS and Volume SS2. Currently studying at a university. Mikoto often comments her mother acts more like a child than she does. This causes their relationship to be slightly antagonistic, as Misuzu's irresponsibility and immaturity is the polar opposite of her daughter's mature and responsible nature, with the latter regularly and openly shouting "shut up, stupid mother" in public and the former frequently teasing her daughter's for her lack of "development" and relationship issues. Despite this, they do love each other dearly, as shown when Mikoto is willing to go shopping with Misuzu for souvenirs and tells her mother to not fall for scams.

Misuzu looks very young for her age, and because of this many people assume that she is Mikoto's older sister, and are very shocked when they learn the truth.

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 out in SS1, when she got drunk and clung onto Accelerator, who called a taxi to take her to her accommodation. Touma ran into her when she refused to get into the taxi and ended up exchanging phone numbers with her.

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 the worse case scenario, they are 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 Sports Festival.

Like her daughter Mikoto, Misuzu is the target of the sincere but excessive "affections" of Shirai Kuroko, due to resemblance to Mikoto.
