Runa Yomozuki is a member of the Student Council. She is the leader of the Election Committee who serves as a referee during election gambling matches.


Runa is a girl of a very small posture, looking rather youthful in comparison with other members of the Student Council. She possesses quite light complexion, long platinum blonde hair with short bangs, split in the middle of her forehead and purple eyes. She wears an orange rabbit hoodie over the Hyakkaou Private Academy issued uniform; a red blazer with black trim lining the cuffs and collar, a white button up dress shirt, a dark pleated skirt, a tie and white black striped stockings, as well as the academy's issued footwear, brown colored loafers with black soles. She has light pink painted fingernails and is often being seen with a lollipop in her mouth.



Runa's sweet tooth

Runa is mostly seen as a very cheerful, enthusiastic and kind of charismatic person. Whenever she holds a public broadcast she acts very sweet and friendly. She also has an enormous sweet tooth and is always surrounded by alot of candy. Runa can also be somwhat lazy sometimes and plays a lot of videogames.

However, despite looking friendly and innocent, Runa is just as power-hungry and calculated person as any other students in the academy. She seems to enjoy the infamous house pet system, mocking Mary Saotome when she confronted her over the case of her Life Schedule, telling her that she needs to boost her skills in pleasing guys. Runa seems to be the only member of the Student Council who has a good relationship with the Student Council President as Kirari Momobami is treating her with much respect.

Her actions when Midari Ikishima picked out her own eye, and during the match between Mary, Ryota SuzuiMiyo Inbami and Miri Yobami, shows that she might have no regards of humans life just like Kirari, making her a psychopathic and sadistic individual. But she still possesses an unstoppable sweet tooth and is rarely seen without a lollipop.

Stating, Kirari might become a housepet too

Runa is often seen alongside the president, managing stuff. Most of the time she makes a quirky remark or joke about the situation. She arrives with Kirari Momobami and Ririka Momobami at Yumeko Jabami's gamble with Yuriko Nishinotouin. Runa notes how pale and scary Yuriko looks. Runa also tells Mary about her lifeplan. The person she has to marry is a filthy lolicon, but it could be worse. She then laughs Mary off and tells her to practice pleasing a man.

When Kirari reveals herself as the vice-president, even she is surprised. During the Tarot game, she also acts as the dealer. When Mary notices which card the joker is, Runa warns her not to say a peep. After the game before the others can take a look at the marked card, Runa confiscates it, leaving it unknown. Later she calls Ririka, telling her about the recent events.

She is also present as the dealer during the Nim Type zero game with Yumeko Jabami and the others. Runa doesn't trust Miyo Inbami, especially after she had beaten Yuriko Nishinotouin. Runa shows content, with Mary Saotome tricking and beating Miyo later. She was also leading the battle between Yumemi Yumemite and Kawaru Natari. During the second round she should try a bite of the spicy macaroon. Runa instantly ran off, screaming for water. She was impressed the others could even eat the whole macaroon. She also had the idea for the game of the third round and explained it to them. After that game she counted the number of card and announced Yumemi and Yumeko as the winners. During the second broadcast she once again announces the current top players in the election. She is excited about Yumeko's invitation for Kirari to gamble. Later, she tries to stop Sayaka Igarashi from attacking Yumeko, but she is forced to put the live show on stand by.


Runa declaring the game official

She's soon very bored about the current ongoing gambles, since votes aren't flowing. But she is then very intrigued by the Votes Auction and observes it along with the Momobami's. She explains to them, how Rei Batsubami obtained all those votes for the auction. When Rin Obami organized a fake election gamble, Ririka Momobami saw through his plan and realized, that the present observer wasn't real. So she called Runa, who was listening in on the entire game. Right at the end, she bursts into the room and declares the game as valid and Rin Obami out of the Election.
