As ordered by his previous master, Soubi contacted Ritsuka after Seimei’s death. He introduced Ritsuka to the world of fighters and sacrifices and told Ritsuka that he was his Fighter Unit. Many knew Soubi to be Seimei’s fighter, thus his relationship with Ritsuka was considered taboo because there is no fighter-sacrifice bond between them.
Another beautiful cosplay found on Loveless Cosplay’s Tumblr! If I’m not mistaken, this is a reenactment of one of the covers from the manga. I’m not too sure how accurate the clothes are though! Thanks for sharing this with us!
