Takeru Tanaka was the former apprentice and aide of Omaroch d'Zarnagon and later the Grand Magus of the Magicracy of Alent's Western Army during Omaroch's absence. He was a man with a dry sense of humour who wished to see the magicracy prosper and spread its area of influence over the rest of Libaterra. He perished in the Battle of the Rivers because of the betrayal of Spectre who orchestrated the army's and the magus's downfall.
