Menhera focuses on themes of mental illness, depression, and anxiety, often with a cute and pastel-colored twist. Yami Kawaii, which translates to "sick cute" or "dark cute," is a broader aesthetic that encompasses a range of dark and taboo themes, including mental illness, but also death, violence, and other macabre subjects. In short, Yami Kawaii tends to be darker and more extreme than Menhera.
