Let me introduce you to Kasumi, a Japanese ghost or yūrei, who could not find peace, being invaded by the hatred and vengeance of men, ended up becoming a Yokai who mainly attacks masculine men, before being captured centuries later by a strange agency, completely secret, the Custos Mundi, and then being converted to a black agent who works for this secret agency that studies, investigates, neutralizes and fights anomalis, artifacts, eldritch abominations and aliens in the shadows, against her will.
Expressing little speech and little emotion, this makes her a rather terrifying yokai, by her supernatural aura filled with hatred, by on the ground, she is very effective in seeing the invisible, crossing places impossible to penetrate and deploying a frightening combat power that would scare away the most dangerous of anomalis.
You will discover a little more about Kasumi with each new image I have of her.
