Meiko Honma, universally recognized as Menma, presents a distinctive appearance: long silver hair flowing to her waist, light blue eyes, and pale skin. She stands 147 cm tall and weighs 36 kg, her ghostly form retaining a childlike, slender frame despite appearing older than her age at death. She consistently wears the tiered white dress fastened with a blue bow from the day she died, perpetually barefoot as a spirit—a consequence of losing her shoes during the fatal accident, contrasting her living self who wore simple sandals. Menma embodies a consistently cheerful, kind-hearted, and air-headed personality. She relentlessly focuses on others' well-being over her own, especially concerning Jinta Yadomi. Emotionally responsive, she frequently cries when others are hurt or upset, though rarely for herself. Despite her ghostly state, she radiates positivity and energy, often appearing lively and talkative, yet experiences profound loneliness confronting her separation from family and the loss of her home. Her speech and tendencies remain childlike, likely due to her death at age 10 halting emotional maturation. Curry is her favorite food. Her background centers on a tragic accident five years before the main events. Chasing an embarrassed Jinta after he called her "ugly" during a childhood interaction in their group hideout, she slipped and drowned in a nearby river. This fractured her friend group, the Super Peace Busters. She reappears years later as a ghost visible only to Jinta, seeking to fulfill an unremembered wish to pass on. Her return grants physical interaction with the environment—opening doors, cooking, eating, playing video games—even without Jinta present. Those she embraces sense heavier air or familiar scents, subtly indicating her presence. Menma's relationships define her character. She shares a deep bond with Jinta, rooted in their childhood leadership of the Super Peace Busters. Her romantic feelings for him—described as "the love where she wanted to marry him"—endure beyond death, culminating in a written confession. Her younger brother, Satoshi Honma, recalls her instructing him to guard their home during her outings. Within the friend group, Menma expresses unique appreciation for each member: Chiriko Tsurumi's gentleness, Atsumu Matsuyuki's diligence, Tetsudo Hisakawa's humor, and Naruko Anjou's determination. She holds no resentment toward any for her death. Her narrative involves rediscovering her wish: fulfilling a promise to Jinta's mother to help him express emotions, particularly crying. This journey facilitates reconciliation among the estranged friends, allowing them to confront guilt and hidden feelings tied to her death. Menma's selflessness is emphasized through her focus on others' healing, culminating in her peaceful ascension after the group collectively acknowledges her presence and grants her wish. In expanded media, the anime film reveals she wrote farewell letters to each friend during their search. The 10th-anniversary stage drama, set a decade later, symbolically references her potential reincarnation—a concept her friends embrace as part of her enduring legacy. Menma's impact persists through the Super Peace Busters, who reunite and heal through her posthumous influence, embodying themes of innocence lost and the enduring power of friendship and unresolved love beyond death.
