Ikkyu, also referred to as the devil in the show, hails from the Magic World. He was summoned accidentally to Human World by Ya Sager, a sorcerer. He and Gokudo are very much alike in their scheming ways. Later in the show he starts the girl band, The Bok Choy Sisters, for various reasons. He enjoys devouring souls, skipping out of perilous situations, and cracking jokes.
