OVA
Description
Fuka Narutaki is one of the pink-haired Narutaki twins in Mahora Academy's Class 2/3-A, instantly recognizable by her ponytails and light violet eyes. Standing at 128 cm, she ranks among the class's shortest students, with physical measurements noted as B62-W46-H55.

Her personality bursts with energy and mischief; Fuka delights in pranks and sweet treats but harbors a dislike for ghosts and stationary objects. She possesses a more tomboyish spirit than her twin sister Fumika and often spearheads their playful antics, with Fumika reliably joining in. The twins share an inseparable bond and mutual admiration for their upperclassman Kaede, mimicking her ninja persona through imitation rather than genuine ninjutsu.

Academically strong, Fuka maintains high grades, though not reaching the top marks of classmates like Chizuru. She and Fumika belong to the Strolling Club, guiding newcomers around the vast school grounds. Their ninja training under Kaede progresses only to fundamental skills such as eavesdropping.

During the Kyoto events, Fuka and Fumika simultaneously kissed a copy of Negi Springfield, triggering an irregular Pactio ritual. This produced their unique shared "Geminae Simulatrices" card within their class, granting them limited shadow-cloning abilities when together, though the exact number of possible duplicates remains unspecified.

In the series' epilogue, Fuka aids Negi in rescuing Nagi and defeating the Mage of the Beginning. After graduation, she marries, has a daughter, and settles near Ariadne within the Hellas Empire's borderlands. This marks one of the earliest transitions to marriage and parenthood among her peers.

Fuka's name translates to "windy fragrance." Like Fumika, she retains a youthful appearance reminiscent of an elementary student despite matching her classmates' age. The twins share identical physical statures and academic performance, with Fuka's mischievous streak distinguishing her from her sister in the original manga continuity.
