Kamijou Shiina

Kamijou Shiina is Kamijou Touma's mother. A woman who looks younger than she really is, a fact remarked by Index and many others that saw her. First appeared in the Angel Fall incident, then shows up in the Academy City sports festival (Daihaseisai) and makes a appearance in Volume SS2. Her hobby is paragliding (jumping off heights and gliding down using a parachute), and is famous in her neighborhood for it and her 'ojou-sama' appearance and demeanor. She tends to get jealous when her husband attracts women or when he looks at other women, giving him frightening glares, though he quickly tries to calm her down.

In SS2 she is found to be friends with Misaka's mother, Misuzu, after having met during the Daihasei festival, and meets up with Misuzu at a university pool. Misuzu notes Shiina is probably older than herself yet still manages to look younger than her, without having to work hard to appear so. Also Shiina doesn't look out of place at all at a place fulled with other university students. Shiina and Misuzu appears to get along well and talks about their kids who both study in Academy City often.
