regarding the title, "乱光" isn't actually a word, but can be read as "rankou" (promiscuity/group sex) and uses the characters for "rebellion" and "light", while the "魔術" ("majutsu") just means black magic/trickery. "slut of hand" (play on "sleight of hand") is my attempt at getting the slutty/trickster magic wordplay but idk how well it comes across. oh well
