159cm. 2nd year at Gehenna Academy. Head of the School Lunch Club. Red eyes and black hair in twin tails. Serious, sincere, and full of compassion and love. She joined the School Lunch Club out of a selfless desire to "do something for everyone." She possesses a very normal and common-sense way of thinking. Her cafeteria is routinely trashed by the Gourmet Research Society, and she is often wrapped up like a sushi roll and forced to be their accomplice. She works day and night while fighting various troubles and absurdities, but the resulting fatigue and stress have made her somewhat cynical; while polite to those outside the school, her interactions with students inside the school can sometimes be sharp.

163cm. 3rd year at Gehenna Academy. President of the Gourmet Research Society. Silver hair, red eyes, and pale skin. A student with a graceful demeanor that fits the description of a "refined lady," exuding an air of elegance through her speech and behavior. Perhaps because she has a firm philosophy and way of life centered on "gourmet food," she is usually composed. She drags others along at her own pace to the point where communication is difficult, but she also possesses a sense of duty, willingly offering help to those she owes. She also has a side that becomes visibly flustered when met with an unexpected reaction. Apparently a poor cook, she rarely prepares food herself. While she has feelings for Sensei and actively invites them on gourmet quests, she views Hina Sorasaki only as an "obstacle." Rather than feeling fear or resentment, she usually interacts with her as an equal acquaintance.

167cm. 3rd year in the Gourmet Research Society. Blonde hair. An incredible glutton with records of eating 120 hot dogs, 15 bowls of ramen, and 80 gyoza. Consequently, there are rumors she has a "black hole for a stomach," and she is often banned from all-you-can-eat restaurants. She tends to favor quantity over quality but is still picky about taste. Unlike Haruna, who seeks the ultimate single dish, her goal is to eat her fill of (reasonably) delicious food. Basically a bright older-sister figure who never stops smiling. Her ability to maintain a cheerful smile even in the worst predicaments—or even when her arm is being snapped—is actually terrifying.

149cm. 1st year in the Gourmet Research Society. A bit cranky. Compared to the other members who have no resistance or guilt regarding dining and dashing or plundering food, she is a relatively normal person who works part-time to pay for her food expenses. Even in the heat of battle caused by the society's own actions, she is often the one playing the straight man while the others act carefree. She is self-conscious about having a smaller appetite compared to the other members.

161cm. 2nd year in the Gourmet Research Society. Innocent and cheerful. She possesses a unique sense of taste, liking "bizarre foods," and her favorite is the chocolate hamburger. She is the only person capable of eating Juri's cooking. She holds a firm belief that "delicious things should be shared." She directs strong anger toward acts like playing with food and will resort to force. She has a mysterious talent regarding meals; when she adds her own touch (naturally in a bizarre direction) to a dish that lacks flavor, it somehow becomes a delicious meal. Within the Gourmet Research Society, she is the clumsiest and slowest runner, so she is often used as a decoy to allow the other members to escape from security forces.

167cm. 2nd year. Secretary of the Pandemonium Society. A cheerful, high-spirited, and energetic girl. She speaks with a polite tone. In addition to her blunt way of speaking, she dives into anything without fear. She is a natural charmer who can get along with anyone through her friendliness and sociability. She loves talking to unspecified numbers of people and staying active, belonging to multiple clubs as a guest member. She publishes the Pandemonium Society's periodic newspaper, "Weekly Pandemonium," all by herself and is constantly running around looking for scoops. Although she specializes in the Gehenna Autonomous Zone, she appears anywhere there's a photo opportunity, even crawling under Sensei's desk to catch a story. Weekly Pandemonium is not for profit; subscriptions are free, and it is published almost entirely as her hobby. It has a scheduled break about once every two months.

155cm. 3rd year. Head of the Emergency Medicine Department. Her motto is "speech and action must be precise and accurate," and she always strives for clear language that leaves no room for misunderstanding. Combined with her expressionless poker face, she is like a high-precision machine. She has a mysterious habit of mislabeling injured people as corpses, saying things like, "...Sorry to keep you waiting, where is the corpse?" She loves treating corpses—or rather, the injured—and claims she has "no interest in anything other than corpses" (though she has apparently never seen a real one). She treats the injured somewhat roughly and silences anyone who interferes with medical aid using her hand grenades. Because of her dangerous behavior—calling the injured "corpses" or referring to emergency transport as "delivery" (tossing them into the vehicle)—some students keep their distance. While her excitement rises when she finds an injured person, she also believes that it is best if no one gets hurt, showing that her underlying ethics are sound. On the inside, she is an ordinary girl. When work isn't involved, she gets excited about dates or picnics with Sensei and enjoys chatting.

170cm. 1st year in the School Lunch Club. A rare sensible type, she is a serious, cheerful, and reliable person. She is kind-hearted and devoted. She has a very strong passion for cooking and respects the club president, Fuuka. However, the many dishes she produces end up as disaster-level plates that transcend human understanding. Izumi Shishidou is the only one who can properly finish and enjoy them. If anyone else eats them, they will, at best, faint, and at worst, collapse from food poisoning or even go insane and experience a personality shift. Even the Gourmet Research Society tends to avoid her cooking. Furthermore, it is a daily occurrence for her food to move on its own, leading her to say things like, "It seems the food has gained a sense of self again." Her cooking has reached the level of alchemy.
