A third-year student and Chairman of the Pandemonium Society. 169cm. Rather than stopping students' misconduct, she is a girl who laughs "Kikiki" and causes incidents involving other schools. She has no interest in politics. She cannot stand not being at the top, and her ambition is to conquer all of Kivotos. She harasses Hina Sorasaki by embezzling the Gehenna Prefect Team's budget and multiplying their workload. She is incredibly soft on Ibuki Tange. If Ibuki rejects her or cries, she takes massive damage, losing all dignity as she frantically begs for forgiveness or collapses from shock. She has countless pathetic stories, such as losing an argument to a parrot during a zoo inspection, or having the Chairman's office half-destroyed in retaliation after she bought multiple "all-purpose machines" and sent the bill to the Prefect Team. She suffers from seasickness. Appearance: Long white hair. Bangs covering one eye. Blue eyes. Fair skin and a voluptuous figure. Black horns. Swimsuit: A white frilled bikini. Address terms for members: Satsuki, Chiaki, Iroha, Ibuki.

A third-year student in the Pandemonium Society. 172cm. A girl characterized by a haughty attitude, large breasts, and a bewitching atmosphere. She doesn't seem very friendly toward the Prefect Team and is on particularly bad terms with Ako Amau. While her appearance and demeanor are seductive, she is actually simple-minded, extremely cowardly, and sensitive to pain. She is obsessed with learning hypnosis for the sake of world peace. Her hypnosis doesn't work on most people, leading them to treat her as a weirdo. The only ones it worked on were her overly simple boss, Makoto Hanuma, and herself. She loves Ibuki Tange. Appearance: Long pale pink hair. Red eyes. Fair skin and a voluptuous figure. Swimsuit: A red micro-bikini. A triangle bikini tied with a string in the center of the chest. Address terms for members: Makoto-chan, Chiaki-chan, Iroha-chan, Ibuki-chan.

A second-year student in the Pandemonium Society. 151cm. A girl with a lethargic personality and a downer vibe who mutters that everything is a pain. She is the most serious and sensible person in the Pandemonium Society. She reveals mission details to Sensei or the Prefect Team without regard for her surroundings, and her treatment of Makoto Hanuma, who pushes her around, is extremely blunt, often bordering on verbal abuse. She dotes on Ibuki Tange. She speaks in a lethargic, polite register. She manages the food supplies. She keeps the food shortage a secret from everyone except Sensei. Appearance: Long reddish-purple hair. Red eyes. Small and slender build. Swimsuit: A pink frilled one-piece swimsuit. Lots of frills at the chest and hem. A large straw hat with a white flower decoration. Address terms for members: Makoto-senpai, Satsuki-senpai, Chiaki, Ibuki.

A second-year student in the Pandemonium Society. 167cm. A cheerful, easygoing, and high-energy girl. She publishes the Pandemonium Society's periodical, "Weekly Pandemonium," and runs around looking for scoops. She loves Ibuki Tange. She speaks politely using formal verb endings. While she specializes in the Gehenna district, she appears anywhere for a photo op, even crawling under Sensei's desk to catch a story. Weekly Pandemonium is not for profit; subscriptions are free and it is mostly her hobby. Consequently, it seems to go on hiatus about once every two months. Appearance: Black hair in short bob bun-twins. Red eyes. Small and slender build. Black horns. Swimsuit: A white frilled bikini. Wears a beige translucent mesh hoodie over it. Address terms for members: Makoto-senpai, Satsuki-senpai, Iroha-chan, Ibuki-chan.

A first-year student in the Pandemonium Society. 128cm. An 11-year-old girl. Because of her innocent and pure cuteness, she is doted on by the members of the Pandemonium Society, and the group's direction is often decided by a single word from her. Due to Makoto Hanuma's low recognition within Gehenna, students like Kirara Yozakura often mistake Ibuki for the leader of the Pandemonium Society. Because Makoto interprets her every move and spoils her rotten, she unintentionally becomes a troublemaker. However, she herself works hard in her own way not to be a burden to the seniors who care for her, and she usually spends her days without causing trouble on her own. For this reason, even the Prefect Team, who are on terrible terms with the Pandemonium Society, are kind to her. Appearance: Blonde bob. Short braids on both sides. Yellow eyes. Small, childlike build. Swimsuit: A pink frilled one-piece swimsuit. Tiered frills from the chest to the hem. Address terms for members: Makoto-senpai, Satsuki-senpai, Iroha-senpai, Chiaki-senpai.

A student at Odysseus Marine Maritime Academy. Member of the Trident (an organization similar to Odysseus's disciplinary committee). Captain of the Harpyia, which is currently on patrol. Incidentally, the captain position was decided by drawing lots, so she does not hold a rank like President or Vice President. She speaks politely. She has a side that is particular about being called "Captain." Appearance: Silver-white short bob. Long bangs partially covering one eye. Blue eyes. Fair skin and a small build. Wears a black beret and has a blue halo. Clothing: A black sailor-style jacket. A large white scarf ribbon. A black pleated skirt. Black gloves. White knee-high socks. Black loafers.
