Description
The character referred to as Me or Watashi is the unnamed protagonist of Humanity Has Declined. She is a young woman with long pink hair who serves as a United Nations mediator between the dwindling human population and the fairies, the small, candy-obsessed creatures that have become the dominant species on Earth. After completing her studies at the Academy, she returns to her hometown and takes up the role of arbitrator, tasked with managing interactions between the two groups and resolving the chaotic situations that arise from the fairies' childlike but powerful mischief. She works directly under her grandfather, who heads the mediation office, and is frequently accompanied by a silent assistant.

Her personality is characterized by a sharp, observant nature and a cynical, pragmatic worldview. She often masks her internal frustrations with a polite and professional exterior, but she is prone to dry wit and ironic commentary. She is highly cunning and prioritizes her own well-being, approaching life with a distinctly pessimistic outlook shaped by witnessing the slow decline of human civilization. Despite her detached demeanor, she has a talent for making sweets, which is the primary method she uses to gain the cooperation of the fairies.

Her motivations stem from a sense of duty and necessity rather than idealism. She accepts her role as a mediator not out of hope for a grand restoration of humanity, but as a practical function in a world that is gradually ending. Her primary goal is to maintain a fragile coexistence between humans and fairies, often by containing or cleaning up the surreal disasters the fairies create in their endless search for amusement. She is also driven by a desire to protect the few human communities that remain, including her own grandfather and the people in her village.

In the story, she serves as the central viewpoint character and the audience's anchor in an absurd and post-apocalyptic world. Her role is to navigate the bizarre, often existential crises that arise from fairy interference, ranging from time loops to self-replicating manga industries to malfunctioning ancient technology. She is the sensible mediator between human common sense and the fairies' reality-warping whimsy.

Key relationships include her bond with her grandfather, a laid-back but knowledgeable older man who represents the older generation of humans content to pursue their hobbies in the twilight of civilization. She shares a close but mostly silent partnership with the Assistant, a young boy who follows her loyally and performs tasks with quiet competence. Her friendship with Y, a former classmate obsessed with BL manga, provides a connection to her school days and often drags her into absurd schemes. Her interactions with the fairies are defined by mutual benefit and mutual bewilderment; she views them as both a miraculous source of wonder and a persistent nuisance, and they are obsessed with her because she provides them with sweets and entertainment.

Her development throughout the series involves a gradual shift from youthful ambition to a seasoned, weary acceptance of the cyclical nature of human and fairy existence. Through encounters with time loops, lost technology, and surreal events, she moves from someone who initially believes her task will be straightforward to someone who understands the deeper, often absurd patterns of the world she inhabits. She learns to navigate the fine line between human dignity and the necessity of adapting to a world no longer ruled by humanity.

Her notable abilities include a sharp intellect and keen observational skills, which allow her to quickly assess and respond to the fairies' unpredictable behavior. She is a skilled negotiator and diplomat, though her methods often rely on bribery with homemade sweets. She is also proficient in using knives as a weapon of choice. Due to a fairy-produced hair growth product, her long pink hair becomes alive and can act independently, though this is more of a quirk than a combat ability. She is one of the few remaining humans with the education and temperament to handle the surreal and often dangerous requests of the fairies.
