Hana Kaka

is an Academy teacher in Konohagakure.

Personality
Hana is a friendly soft-spoken woman who is timid with much self-doubt. Wanting to be a good teacher, she struggles at being assertive to get her students' attention. She cares greatly about them, taking care to know their interests, and dedicated to solve their issues. While fumbling often in her actual efforts, her sincerity is apparent to all and is quickly acknowledging by others. Likewise, apart from her general timidness, she is very selfless, driven to protect her students in the face of danger, even if she herself will get hurt in the process.

In episode 270 it is revealed that she suffers from multiple personalities

Appearance
Hana is a pale-skinned woman of average height with red eyes. She has waist-length black hair with red tips. Her hair is straight and is held in a side-ponytail on the end that hangs over her right shoulder. She wears a Konoha forehead protector, a long purple skirt and shirt over a grey mesh shirt and leggings with black kunoichi sandals.

Abilities
Hana is skilled with Wind Release, being able to knock down a small group of students with a torrent of wind, though she was unable to defeat a flame bear, because her attacks are mostly of an auxiliary nature and do not have much power. According to Anko, Hana scored very well in employment tests, showing extensive practical knowledge in teaching.

Kawaki & Himawari Academy Arc
Hana attended the welcoming ceremony for the newest students. Later, she was accompanied by Anko Mitarashi to help the new teacher adjust to her first class. Despite her efforts, Hana's natural shyness made it hard for her to get the students' attention. Later, she voiced her concerns about being able to handle the job. Her fellow teachers however assured her that everyone struggled with the job at first.

When Hana invited Team 7 as special instructors for her class, she was disheartened that her students seemed more interested in their flashy jutsu. When some of them got too close to their more dangerous jutsu, she pushed them away with Wind Release, concerned for their safety. She got concerned for her students when Team 7's exercise created a divide between them, and looked up on Ehō and Soul, to find out how to reconcile them. Despite making mistakes in her attempts, her commitment to getting them to move past their animosity got though them, and she cancelled class for a day to have a cherry blossom watching party during a picnic.

Hana had the class go through a practical lesson to build up their team-work, sorting them in teams of three. The lesson took place in a hill near the Academy, and she warned them not to go too deep in the nearby forest. When Himawari and Kae were attacked by a flame bear, she distracted it to allow them to escape. She was unable to defeat the bear on her own, requiring Kawaki to save her, causing him to admonish her.

Later, Hana had her class prepare a play about the Sannin for a festival. The day of the festival, she wished her students put as much effort in class as they did for the event, and left to rest, having overworked herself for the event the night before. When the festival received a terrorist threat, she discussed their options with other Academy staff. When she discovered there were students missing, she went to look for them, and was caught up by debris of an explosion set off by an assassin that was targeting Kae. She was taken to the hospital, and was soon visited by her students, who wished her a quick recovery. When Kawaki asked her if she saw the assassin's true face, Hana couldn't remember anything, and after her students left, Hana pushed herself to try and remember.
