Danbo, also known as Danboard, originated from the popular manga 'Yotsuba&!' where one of the characters dresses up in a cardboard box costume for a school project. Since its debut, the character has transcended its manga origins to become an internet icon of melancholy, innocence, and aesthetic photography. Frequently depicted in professional toy photography as a lonely figure navigating a vast, human world, Danbo memes often focus on themes of isolation, simple curiosity, or the ironic humor of being a sentient shipping package. Its minimalist design—consisting of two circles for eyes and a small triangle for a mouth—makes it incredibly expressive despite its rigid structure, securing its place as a staple of internet culture and 'kawaii' aesthetics.
