Master Therion (マスターテリオンMasutā Terion?)
Voiced by: Hikaru Midorikawa (anime), Hikaru (PC)
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.
He is the child of Nero, "the greatest and most wicked magician in the world," and the Outer God Yog-Sothoth.
