145cm. A third-year student at Abydos High School and the president of the school's Foreclosure Task Force. She originally served as the Vice President of the Student Council during her first year. After the Student Council became effectively defunct, she founded the Foreclosure Task Force alongside Shiroko and Nonomi when she entered her second year. Although she is the oldest member of the group, her lazy personality and speech are prominent—often saying things like "Whew, let's just take it easy~ relaxation is important~"—which frequently earns her scoldings from the serious Serika. She jokingly refers to herself as an "old man." While she acts casually toward Sensei, she remains distrustful of other adults, likely due to a history of being deceived by "bad adults" and exposed to harsh conditions. While her state has improved thanks to her juniors, she is still haunted daily by the deep trauma of losing her senior, Yume Kujiragi, who died of exhaustion following a bitter falling out. She refers to Shiroko Terror as "the other Shiroko-chan" or just "Shiroko-chan."

160cm. A second-year student at Abydos High School. She is a member of the Foreclosure Task Force and acts as the group's mediator. She is a young lady from a prestigious family who possesses a Gold Card, but for certain reasons, she currently lives away from home and enjoys her days at the impoverished Abydos High. True to her soft and fluffy appearance, she has a gentle, innocent, and sociable personality. Though a bit naive about the world, she is caring and the type to devote herself to others. Within the committee, she often supports everyone by looking after Hoshino, following up on Serika, or cleaning during her free time. Her hobby is window shopping, but since there is nothing around Abydos, she frequently travels to the outskirts to restock supplies. Most of the Task Force's "operation expenses," such as snack money, are paid out of her own pocket. She uses her Gold Card freely and is surprisingly loose with money, but for a specific reason, using it to pay off Abydos's debt is considered a unanimous taboo. Thus, she works part-time jobs and brainstorms with her friends to repay the debt. She has been friendly toward Sensei since their first meeting and sometimes tries to spoil them behind the scenes. Her love for Sensei is quite heavy; she looks for every opportunity to interact, getting deeply moved just by receiving a reply, forcing Sensei to go out for dessert by pretending it was a chance encounter, or accidentally letting slip that a shopping trip was actually intended to be a date. She refers to Shiroko Terror as "the other Shiroko-chan."

156cm. A second-year student at Abydos High School. In a school where the student population plummeted from thousands to just five due to the desertification of the surrounding area, she is a member of the Foreclosure Task Force working to save the school from financial ruin and closure. She has a habit of saying "Nn..." before speaking. She is a beautiful girl with a mysterious aura, featuring medium-length silver hair and heterochromia (one eye white, one eye black). She also has piercings in her human ears. True to her appearance, she is a cool beauty of few words, but she also has a battle-hungry side. When facing Hina, Gehenna Academy's strongest individual combatant, she attempted to charge in without hesitation and looked disappointed when stopped, saying, "I thought I could fight someone strong." She refers to Shiroko Terror simply as "Shiroko."

153cm. A first-year student at Abydos High School. A member of the Task Force trying to save the school from the brink of closure. She has long, beautiful, supple black hair tied in twin tails. A classic tsundere, she has a strong rebellious spirit and is always prickly, but within Abydos, she is the most serious and sensible person after Ayane, serving as the vital "straight man" of the group. Although she makes spiteful remarks about the debt-ridden Abydos, saying things like "it should just collapse," she is actually a hard worker who takes on various part-time jobs behind the scenes for the sake of the school. On the other hand, perhaps because her thought process is too direct or because she has struggled so much against the debt, she has a bad habit of falling for suspicious get-rich-quick schemes despite her high level of caution. She often proudly presents shady business ideas without realizing she's being scammed, earning her pitying looks from the others. She refers to Shiroko Terror as "the other Shiroko-senpai" or "Shiroko-senpai."

153cm. A first-year student at Abydos High School. She serves as the secretary of the school's Foreclosure Task Force. Her trademark is her Wellington glasses, which match the color of her halo. Her pointed ears peek out from her black bobbed hair styled with a braided headband. Just as she looks, she is serious and sensible. Because she is usually mild-mannered, she is terrifying when she actually gets angry, to the point where even her seniors can't stand up to her. She refers to Shiroko Terror as "the other Shiroko-san" or "Shiroko-senpai."

165cm. Abydos Student Council. Shiroko herself from a different timeline. She is called "the other Shiroko-chan," "the other Shiroko-senpai," or just "Shiroko." Compared to the original Shiroko, she has a more mature physique and appearance, with longer hair and a better figure. While she usually wears a black dress, this time she is in a maid outfit. She carries an air of resignation, and her eyes are hollow as if drained of emotion. Her halo is almost identical to Shiroko's but is sharp and black. In her timeline, Sensei was mortally wounded and became a vegetable, and every other member of the Task Force died, leading to a disastrous situation. Since the final chapter, she has reportedly been living a nomadic, rootless life centered around the Abydos desert. She maintains a certain distance from the committee members while engaging in vigilante-like activities. Although a different entity, she is fundamentally the same person, so her personality is similar to Shiroko's. Her verbal habit of saying "Nn" is still present. She refers to Hoshino Takanashi as "Hoshino-senpai" or "Senpai." She refers to the other members by their first names without honorifics.
