Description
Hifumi Ajitani is a 16-year-old second-year student at Trinity General School, where she serves as the head of the Supplementary Lessons Department, a club formed to help students who are struggling academically. Despite holding this position, she originally belonged to no club and only joined the supplementary lessons to make up for missed examinations. Her physical appearance is generally unassuming, featuring a youthful face and light brown hair styled into low twintails, but she stands at a height of 158 centimeters, making her somewhat taller than several of her peers. She is consistently seen carrying a large backpack featuring Peroro, a character from the Momofriends franchise, which contains various helpful items.

In terms of personality, Hifumi is defined by her gentle, kind, and empathetic nature. She willingly listens to the troubles and worries of those around her, which has made her genuinely popular among her classmates even though she lacks outstanding traits. She tends to be very modest, frequently describing herself as an ordinary and average girl, and struggles to recognize her own positive qualities even when others praise her. Her desire to be helpful sometimes leads her to go along with the mood of a situation, which can inadvertently draw her into problematic or troublesome circumstances. Her most defining characteristic is an intense passion for collecting merchandise of the mascot character Peroro. This enthusiasm is so powerful that she has been known to skip or miss school tests to attend Peroro concerts and events, a habit that directly contributed to her needing supplementary lessons. Her dedication to her hobby also drives her to take significant risks, such as venturing into dangerous locations like the Black Market to acquire limited-edition goods.

Within the story, Hifumi’s role often sees her acting as a supportive figure and a bridge between different characters. Although she considers herself unremarkable, she has earned the trust and recognition of influential students, receiving personal requests from the Tea Party leader to assist the teacher. Her tendency to get swept up in events leads her to be present during many key incidents. For example, while searching for rare merchandise, she was rescued from delinquents by the Foreclosure Task Force and later became accidentally involved with a group known as the Masked Swimsuit Gang, even being pushed into the role of their leader, Faust, during a bank robbery. She is a core member of the补习授课部, where the concealed purpose of the club is to investigate a potential traitor; her own frequent visits to the Black Market and associations with suspicious groups briefly made her a person of interest in that investigation.

Key relationships are central to Hifumi’s experiences. She forms a close friendship with a fellow club member, bonded by their shared love for Peroro and Momofriends merchandise. This connection becomes important as she tries to share her interests and show her new friend new experiences, like the ocean. Her relationship with the teacher is also significant, as she is specifically requested to support their work, and others note her unique tendency to become entangled in extraordinary events. Her gentle and approachable nature means many students confide in her, finding her a reassuring presence even if she cannot always provide a concrete solution to their problems.

Throughout her experiences, Hifumi demonstrates notable development, evolving from a passive helper who simply goes along with situations into someone with a much stronger resolve. She grows an iron will and develops the determination to actively fight and protect her friends from threats. In terms of abilities, she is a surprisingly capable combatant. Despite her ordinary self-assessment, she proves strong enough to fight alongside skilled allies against formidable opponents, especially when guided by the teacher. Her signature customized weapon is an assault rifle she calls My Necessity, based on the SA80 platform. Her tactical abilities in combat include summoning a Peroro plush doll to draw enemy attention and deal area damage, reducing enemy accuracy, and enhancing her own durability. She also carries flashbang grenades on her backpack. Participating in significant battles, she has fought alongside students from other schools against major adversaries and played a supporting role in helping allies during large-scale conflicts.
