Tsuchimikado Maika

Tsuchimikado Maika (土御門 舞夏) is a side character in the Toaru Majutsu no Index series. A maid-in-training, she is the younger stepsister of Tsuchimikado Motoharu.

History
It has not yet been explained exactly what her history with Motoharu is beyond the fact that she is his step-sister, it has however been hinted at in the light novels that the two of them have had a very close sibling relationship for some time. It is unknown if she is aware of Motoharu being a former magician or about magic at all.

Personality
Maika can usually be found riding atop an academy city cleaning bot. Interestingly, despite the machine's constant spinning motion, she never seems to get dizzy. She is a good friend of Mikoto as she works as a maid at her dormitory. Even though Maika makes her official residence at her school's dormitory, she sometimes chooses to live at her brother's apartment; for instance, she once stayed at said residence because her dormitory's air conditioner had broken down.

At one point, Misaka Mikoto surmised that Maika may perhaps be into "Boy Love" stories, however, Maika almost instantly refutes this, stating with a big smile that her favorite books are the ones where the older brother falls in love with the younger sister. This further reinforces the case for her apparent love of Motoharu.

Despite the formal and polite nature of the vocation she has chosen to study (as an "imouto's promise" to her brother ), Maika is gleefully unprofessional and casual, openly referring to people by their family names without using the polite-suffix of "sama" or "san" in the way a maid normally would. Point in fact, her boyish way of speaking without using any honorifics required by the catering profession would more than likely land her in hot water should she follow through to an actual career as a proper maid.

As the maid school isn't involved in the developing of abilities, Maika is described as one of those "rare people" that exist inside of Academy city, aren't an adult, and yet haven't been "altered" in any way in order to gain ESP powers.

She is an expert cook and can easily dissemble the ingredients and cooking process of high class cuisine just by evaluating the dish for a short period of time, she is also self demanding when it comes to cooking, and can easily get fired up if she sees someone create high class cooking.

Appearance
Maika has short, blue-black hair swept back by her bonnet that barely reaches her shoulders. She wears a maid attire because she's a student at Ryouran Maid School. She has a friendly relationship with Touma and Index. She can be seen constantly riding atop a cleaning bot.

Since the maid school has classes every day, she never wears anything but her mandatory maid outfit -- a fact that she has pointed out proudly.

Chronology
She makes her first appearance in the 3rd novel greeting Touma and Misaka Imouto. She becomes aware of Index and Aisa's presence in his apartment room.

Throughout the series she is well known for performing what is commonly called "almost girlfriend services" to Motoharu. Services that include and are not restricted to cooking for him, massaging him, cleaning his room and taking care of his health. All of those are performed on regular basis whenever she can muster enough free time.
