Her name is lukari its basically like those leaping husks except not infected how she would work in game is that shes like cloths ex friend, they arent enemies but they parted ways due to one wanting to be a pacifist and the other wanting to be an adventurer. lukari can be encountered in multiple locations such as dirtmouth, outside the black egg, and the queens gardens and station. eventually you would have the option to break her lifeblood lantern, if you do, she would become mad but nothing bad would happen, however, if you dont break it she would eventually be overcome by it and initiate an optional bossfight if certain conditions are met she can be seen mourning cloth in queens gardens.
this is for a contest character by me, based off of hollow knight guess who made the art ;)
