Plot

Humanity Has Declined is set in a post-apocalyptic world where the human civilization has regressed and humanity keeps decreasing in numbers. The story follows an unnamed girl who acts as a mediator between humanity and the "fairies" who are small elf-like creatures attracted by sweets and happy things, but also have the habit to cause trouble to her with their powers in their endless search for amusement.

Characters

• Protagonist (主人公)
• Generally referred to as either "I" (わたし) or "Ms. Sweets" (お菓子ちゃん), the heroine is a sensible mediator between humankind and the fairies. She is one of the few humans left capable of creating sweets, which causes the fairies to naturally flock to her. Having observed the slow decline of humanity, her outlook on life is grim.
• Grandfather (祖父)
• The protagonist's grandfather, a researcher and firearm fanatic. Thanks to the fairies, he met with his granddaughter when he was 13 years old and a time paradox was created.
• Assistant (助手さん)
• A young boy in a Hawaiian shirt who almost never speaks and serves as the protagonist's assistant.
• The Fairies (妖精さん)
• They are mysterious beings with advanced technology that could be called magic. The fairies have permanent smiles on their faces and very literal, honest viewpoints on everything. Despite their cute appearance, they seem to have a total disregard for human safety. The presence of many fairies is supposed to increase one's fortunes, but they cause potentially fatal situations. They often request sweets from the protagonist in exchange for their assistance.
• Y
• An old classmate of the protagonist's whose job is to identify human artifacts. She discovers a yaoi doujinishi from our era, however, and then spends her time self-publishing yaoi doujinshi.
• Pion/P-ko (ぴおん/P子)
• A humanoid robot with cat ears. She makes sound effects whenever she acknowledges something of interest. Her original name is "Pioneer".
• Oyage/O-taro (おやげ/O太郎)
• Pion's partner, who she is searching for. His original name is "Voyager".
• Curly (巻き毛)
• The protagonist's classmate from her school days, who is disturbingly affectionate.
