Akarin is the nickname of Akari Akaza, the main character of Yuru Yuri, the slice of life comedy manga by Namori that became an anime in 2011. Despite being the protagonist, Akari is jokingly treated as lacking presence, which made her name and its affectionate shortened form stick with fans. Clips calling 'Akarin~!' spread through anime forums, videos and soundboards as a shorthand for the character. It sits alongside other anime catchphrase clips like Tuturu in soundboard collections, and remains popular for edits celebrating or gently mocking Akari.
