|King of Thieves|
Tōzoku no ō
King of Thieves (盗賊の王 呪法, Tōzoku no ō) is a Curse that allows the user to, when making physical contact, or even intense eye contact, with another Mage or Demon, absorb their life-force, soul and even their Magic and Curse power, respectively, which adds onto the user's own, thereby increasing his or her own amount of Power. Hence the name of the Curse. However, it should also be noted that it has a different effect against Demons: for example, when Tsukisasu used it (albeit accidentally) on his fellow guildmate Kyouka, he permanently gained use of her Enhancement Curse, and obtaining complete use and ownership after her death at the hands of Minerva Orlando.
This Curse was based on inspiration from the powers of Rogue from Marvel Comics.
