Kongou Mitsuko

Kongou Mitsuko (婚后 光子) is a minor character that appears in the Toaru Kagaku no Railgun side-stories. Being a Tokiwadai Student and Level 4 Esper, her pride often result in her getting involved in unfortunate situations which however overshadows her obviously strong abilities.

In the novels, she first appeared in volume 8, but her character design was never shown until the anime aired. Furthermore, she makes her debut earlier in the anime than in the manga, the latter makes her move into Tokiwadai Middle School in the middle of summer.

Appearance
Her most distinguishing feature is her prominent forehead which is flanked by two fringes of her black hair which is rather long and kept neatly. Mitsuko has an attractive and well endowed figure, which she proudly flaunts and shows off in revealing swimware when she is able to. She almost always appears carrying around her fan.

Personality
She is proud of herself most of the time despite being newly transferred and possesses traits of a real ojou-sama, unlike Misaka Mikoto who is the complete opposite, because of this personality she is often at odds with Shirai Kuroko. Because of this personality however, she is completely unaware of common everyday things such as finding directions or how to use the proper tool for foodstuffs.

She often embellishes the truth for her own convenience and will try to stretch the truth until she can no longer keep up the facade, this was shown in episode 13 of the Railgun anime where she lies to her friends that she can cook curry wherein fact she didn't know how. Despite this she is an honorable and decent girl looks out for her friends, is kind to children, and is willing to help people in need.

This is displayed in episode 23 of the Railgun anime where she helps Mikoto after she was defeated by Therestina. She comes to her self-proclaimed rival/friend's aid a second time in episode 24 and fought by her rival Kuroko's side to buy Mikoto time to help Professor Kiyama save her students. During this battle, she and Kuroko come to grudgingly respect each other as warriors.

She also tends to warn her opponents by reminding them who she is and is confident of her own abilities. It is also worth noting that just like Kuroko, Mitsuko is very frank about her sexuality and loves to flaunt and show off her well-proportioned body; though in her case its justified by her part-time career as a swimwear model.

Her lofty attitude however, is played lower in the Toaru Kagaku no Railgun manga shortly after her debut.

Background
Much of her past is unknown though it is revealed that she lead a life of luxury and was surrounded by doting servants when she was younger. She is the heiress of the Kongou Aviation Industry which was held in high regard by the aviation industry.

Eventually she came into Academy City and enrolled into its curriculum in another school. After being disappointed by her school she transferred into Tokiwadai Middle School after 1 year of preparation as a second-year student despite the apparent difficult of transferring to Tokiwadai Middle School.

She is currently residing in the Tokiwadai's dormitory located within the School Garden.

Toaru Kagaku no Railgun
Mitsuko debuts on the very first episode of the anime, where she is seen boasting of her abilities to Shirai telling her that she will become Tokiwadai's ace. She is however falls to the ground after a powerful shockwave is emitted from the pool, here Shirai points to Mitsuko that it was the power of the true Ace of Tokiwadai, Misaka Mikoto.

As Wannai says she will help find Mikoto's sister through the use of a Psychometer friend of hers, and takes her leave, Mitsuko is approached by Baba Yoshio, talking about Mikoto's sister. He later lures her into an empty field, and coerces her with his robot dogs about information regarding Mikoto's "sister."

Mitsuko shows up boasting that herself will reach Level 5 before Kuroko, and then asks Kuroko whether she wants to start a faction with her in an attempt to gather political power within the school. Kuroko declined since if Mitsuko could actually create a faction of notable power the other factions would have crushed her already to prevent that happening.

It was later shown that Mitsuko doesn't need objects to propel, as she can use her powers on the ground to create ejection points of air to create powerful gusts of wind. Her ability is powerful enough to propel an entire satellite dish along with its tower, as well as an entire wall.

Trivia

 * Episode 13 of the Toaru Kagaku no Railgun anime introduced Ekaterina, Kongou Mitsuko's female Boa constrictor. While Mitsuko was in her red swimsuit, she wore Ekaterina as a sort of feather boa replacement. This may be a reference to the pirate empress Boa Hancock of One Piece fame, as she and Mitsuko share similar features.
 * In the anime adaptation of Toaru Kagaku no Railgun, her being the first victim of an incident is a recurring event.
