Black Glasses, known as Black Blind Man on the street, is one of the top lunatics in the world of inversion. He is cold yet gentle, bloody and cruel yet humorous and considerate. In the long years since he was born, he has seen many people and many things; some made him happy, some made him sad; some had solutions, and some had no solutions - in his eyes, most things in the world have solutions, it's just about whether he has the ability to solve them - except for death.
