Nanoha Takamachi

Nanoha Takamachi is the main protagonist and titular character of the anime series Magical Girl Lyrical Nanoha, and also appears in Triangle Heart. To use the abbreviated forms of the series, Minami Hokuto plays her in Toraha, and Yukari Tamura in Nanoha. She has a strong aptitude in magic, a rarity for those born on Earth, amongst these numbered few are Gil Graham, Hayate Yagami, and possibly her own father. She is a quick learner in the magical arts and exceeds expectations consistently throughout the series. In Nanoha, instead of having a familiar of her own creation, she is partnered with another mage named Yūno Scrya from Mid-Childa, who can shapeshift into a ferret. Her weapon is an artificially intelligent staff called Raising Heart.

Personality
In the first series, she is more of a thoughtful and somewhat naive girl. She has a deep, kind personality but later becomes much more mature and ladylike in StrikerS. Nanoha is also rather energetic and idealistic, showing a certain joie de vivre.

A major aspect of Nanoha's personality is that she always tries to understand other people. As such, she's shown to always take a diplomatic approach to problems and tries to reason with her enemies at first. However, she's also shown to be a pragmatic heroine, as she's not afraid to use force if communication alone is not enough.

The Movie 1st manga adds more aspects to her character. Before she became a magical girl, she was shown to be somewhat depressed, seemingly lacking a purpose in life. When she was little, she often felt helpless and wished for the strength to change things.

In Nanoha
As the series opens, Nanoha Takamachi is presented as a regular little girl, living with her family, taking the bus to school and playing the gold-hearted average girl to her multimillionaire best friends Alisa Bannings and Suzuka Tsukimura. However, she always felt like a third wheel; her parents had each other, so did her siblings, and so did her best friends, while Nanoha had no such close companion. Additionally, she says she feels her life has no direction, as she has no plans for what she wants to do with herself. When she finds the injured Yūno in ferret form in the park, she brings him to a nearby veterinarian for care. Yūno later calls Nanoha telepathically as an unstable Jewel Seed attacks him, and he then gives her the red jewel around his neck, known as Raising Heart. With his instructions, Nanoha activates Raising Heart, and discovers her own magical ability. Her power blows Yūno away as she is able to create attacks quickly, transform and attack without using the incantations generally required doing so, and sensing Jewel Seeds more easily than he can. Even with all this power, she is still learning and must fight off her rival (later dearest friend and partner) Fate Testarossa, although Nanoha is more interested in befriending her. Needless to say, she succeeds in befriending Fate, however her methodology has lead to an interesting pun.

Nanoha lives at her home above Midori-ya, the cafe owned by her family in Uminari City, with her mother Momoko, her father Shirō, her brother Kyōya and her sister Miyuki, the latter two of whom served as the main characters of Triangle Heart. Nanoha balances cram school, regular school and hunting for Jewel Seeds with ease, although Yūno fears that it may be too much for her in the long run. Although she tries to hide her identity from her friends and family, in contrast to many mahou shoujo series, she blatantly advertises it to Fate.

Later on, the series focuses not on the collection of Jewel Seeds but on the eventual team up of Nanoha and Fate, which does happen in the second-to-last episode as Fate comes to terms with her and her mother's identities. Nanoha and Fate must part as Fate is arrested for the work she did for Precia, but they part as friends and promise to reunite, as Fate will likely be acquitted of all charges.
