Yowane Haku is a fan-made derivative of the famous Vocaloid Hatsune Miku, created by the artist CAFFEIN in 2007. Her name literally translates to 'uttering complaints' or 'white breath,' perfectly capturing her persona as a 'Voyakiloid'—a character representing the frustration of users who struggle to make the Vocaloid software sound good. Often depicted with a bottle of sake and teary eyes, Haku has become the unofficial mascot for failure, burnout, and relatable depression in the anime community. Her memes typically feature her in various states of distress or intoxication, used to mock one's own lack of skill, social anxiety, or the overwhelming weight of daily responsibilities.
