Seria is Kamijou Touma's senpai, a third year student going to same school as him and described as a genius. She's currently employed by Kaizumi Tsugutoshi as his adviser, one of the 12 members of the Academy City's Board of Directors. She's very knowledgeable in things happening on the Science side, knowing about Deep Blood, Imagine Breaker, and the Level 6 Shift project.

Personally she's very interested in Touma and his ability Imagine Breaker. To resolve the issue of governments and/or various other agencies from forcibly taking control of natural born espers, or 'gemstones' in SS2, to try and build another esper research facility (even though according to her the chance of them discovering a way before they end up killing the gemstones like lab rats is zero) opposed to Academy City, she proposed using the SISTER clones that's going through adjustment in various parts of the world to collect the 50 or so 'gemstones' and keep them under their protection. It is implied she made some sort of deal with Heaven Canceller in order for the SISTER clones to be mobilised.

She's also mentioned in passing in Volume 19, when GROUP needed an ally on the Board of Directors to fight against the Director after them they ruled out Kaizumi as a option, since Seria would not be fooled easily and might advise Kaizumi against helping them.

Set in a city of not only scientifically advanced superhuman students, but in a world where magic is also real. Kamijyo Touma's right hand, the Imagine Breaker, will negate all magic, psychic, or divine powers, as well as his own luck. One day he finds a young girl hanging on his balcony railing. She turns out to be a nun from the Church of England, and her mind has been implanted with the Index Librorum Prohibitorum&mdash;all the magical texts the Church has removed from circulation.

The third season of Toaru Kagaku no Railgun. 

The Daihasei Festival has begun, and that of course means that Tokiwadai Middle School—a prestigious all-girls' middle school—is competing too. Despite the participation of the "Ace of Tokiwadai," Mikoto Misaka, the other students who are participating are still putting their utmost effort into winning, no matter how impossible the feat may seem against her might. 

However, not all is fun and games. Due to the festival, Academy City opens to the outside world, and various factions have begun plotting ways to infiltrate the city. Misaka appears to be on their radar, and as the festival proceeds, people lurking from the shadows begin to emerge... 

Toaru Kagaku no Railgun T brings back the Tokiwadai Ace and her friends as they dive deeper into the dark side of Academy City. From terrorist attacks to ruthless underground projects, anything is possible in this city.

A backward glance from the default misfortune-prone bastard, the silver-haired sister freeloading in his dormitory, Index, in the heart pounding scene different from the usual, activates a new gluton skill!?
