Suzuka Tsukimura is a minor character of the Magical Girl Lyrical Nanoha series. The younger sister of Shinobu Tsukimura, Suzuka is a civilian and best friends with Nanoha Takamachi and Alisa Bannings. In Magical Girl Lyrical Nanoha A's, she befriends Hayate Yagami, not knowing of the war between Hayate's protectors the Wolkenritter and the Time-Space Administration Bureau, for which Nanoha works. Suzuka does not exist in Triangle Heart.
Suzuka is a grade three student in the same class as Nanoha and Alisa, and already sure what she wants to do with her life: continue on her family tradition of rich, successful engineers. She lives in a huge mansion with her maids Noel and Farin K. Ehrlichkeit, sister Shinobu and many cats, one of which is affected by a Jewel Seed. As a small child, she was bullied by the more aggressive Alisa, but Nanoha stood up to Alisa and the trio became friends. When Alisa strikes out at Nanoha and stops speaking to her because she can tell that Nanoha has been keeping secrets, Suzuka stays with Alisa and slowly but eventually changes the other girl's mind so they reconcile again.
In the second Nanoha season, Suzuka befriends Hayate Yagami when she helps the wheelchair-bound girl reach a library book. She greets transfer student Fate happily, as well as the return of cute "pet" Yūno, and continues in her complete ignorance of the magical situation until late in the series. Suzuka and Alisa are trapped in a magical barrier and bear witness to Nanoha and Fate's battle with Hayate possessed by the Book of Darkness. Later, Suzuka, along with the other civilian characters, are let in on the secrets of what Nanoha has been doing all this time.
In the A's epilogue, Suzuka still goes to school with Nanoha and Alisa and remains their close friend.
