Hikimayu

This character has Hikimayu-styled eyebrows, or drawn round eyebrows on the forehead.

In pre-modern Japan, hikimayu was the practice of removing the natural eyebrows and painting smudge-like eyebrows on the forehead.

Aristocratic women used to pluck or shave their eyebrows and paint new ones using a powdered ink called haizumi, which was made of soot from sesame or rape-seed oils.
