マスターテリオン

Current head of the Black Lodge and titled as Grandmaster, this youth with a contemptuous, bored expression cares little about those who cannot match his vast, mystical power, thus allows Kurou to survive their many scuffles so as to provide him a challenge and amusement. Master Therion also controls the Deus Machina Liber Legis.
