- "I don't know what I did wrong, but I'm sorry!"
- ―Kuki after Daruma hit him for surprising her.
Kuuki (クウキ, atmosphere?) was the math teacher and homeroom adviser of Class 2-C, and the only known teacher in Majisuka Jyogakuen. He was tasked by Principal Nojima Yuriko to watch over Maeda Atsuko, and became aware of her true potential through the principal's stories. After Atsuko defeated the Rappapa members one by one, he learned of the dark reason behind Atsuko's transfer to Majijo. He was last seen in the graduation ceremony of Oshima Yuko's Rappapa. He was portrayed by .
In this world, there is nothing but seriousness!
Kuuki's first appearance was in Room 2-C, where he was trying to teach Fractions, while Team Hormone and their classmates are minding their own. Trying to interact with his students, he asked Wota if she would like to answer the math equation, but was instead burned by a piece of sizzling hormone-yaki. Several minutes later, Onizuka Daruma and Maeda Atsuko arrived at their school and were assigned in his class. He then went to introduce the two to their new class. While Daruma was rude, he was surprised by Atsuko complying to his suggested seat for her, but still feared the girl because he knew which of the two was the one Principal Nojima was expecting. After trying to stop an argument between Team Hormone and Daruma, he got hit instead and went to the infirmary to get some help. He was then called by Principal Nojima, who mistook his wound as being from Atsuko.
One day, he was staring at the chalkboard as usual, when the Sanshou Sisters arrive in his class and beat down Daruma. Surprised, he tried to stop them, but he got scared and ran away.
The Most Evil Shitennou Gekikara, Laughing!
While walking down the stairs outside Majijo, Kuuki bumbed into Daruma, who thought he was Gekikara. Surprised by each other, Daruma hit him with a headbutt, while he then confusingly apologized.
After resting, Principal Yuriko called for him again, revealing the real reason why she had Atsuko transfer to Majijo, which Daruma overheard.
