Static

Static

The character is the first love interest of Yuki during "Once Upon a Yandere".

Biography
Static lives with his carer Skylight Dreams in a house opposite Yuki's during their time at Baku High School. As a child they were created and experimented on in a lab, which led to their blindness.

As they were created in a lab, they have no belly button, and so when they did escape (presumedly with the help of Skylight), and were mocked for not having one, they tried to give themselves one through self injury. This backstory is shown in Yuki's dream in episode 26 of Once Upon a Yandere.
