Yami Kawaii (病みかわいい) is a Japanese aesthetic that was originally born as opposite to the pastel Yume Kawaii aesthetic. The Japanese word "yami" can mean both "dark" or "sick", and refers to its use of dark colors and motifs related to sickness.

Yami meaning Darkness and Kawaii means Cute.

Yami kawaii meaning Dark Cute. As to being known as cute but dark/suicidal. It is a relatively new sublevel of harajiku in Japan.
