Fuka Narutaki

is the older sister of the Narutaki twins. She's the one who's mischievous and likes to play silly willy pranks on other people. Fuka and her sister both love to play ninjas like Kaede, though their ninjutsu is not at the level of Kaede's. It in fact isn't even real ninjutsu at all. Fuka and her twin sister have the smallest breasts in 3-A which is about as flat as Negi's. Fuka can be discerned by the ponytails in her hair and her tomboyish nature. All the same, when Fuka decides to pull off a prank, Fumika is always there by her side. The two are inseparable.

Abilities

 * Ninja Skills- She and her twin claims they are undergoing ninjutsu training from Kaede. It is supported as they are seen wearing ninja outfits, and their paction card shows them in ninja uniform with a scroll and a dagger.


 * Other Skills- As a member of the Strolling Club, she is well-versed in going to the school's common locations and easily toured Negi across the school premises. Other than that, Fuka has a mischievous nature doing pranks on others.

Personality
Fuka is in all a prankster. She loves having a great time playing around and pulling pranks. Unlike her sister, she is full of energy and never worries about the consequences. Fuka is in the walking society with her sister Fumika and Kaede. She and her sister look up to Kaede and listen to her intently. They admire her so much that they even use fake ninpou to look like they have inherited the skills from Kaede herself.The fact that she wants to grow as fast as she can does not in fact please Kaede but it shows that she can be serious at times. She cares deeply for her sister and is loyal to the walking society. She likes teasing her classmates on their weaknesses. She also looks like a child and is seemingly shorter then Negi even with the four year advantage.
