Yuu Kaitou

Kaitou Yuu is a human who develops superhuman powers as a result of the demon plane hole opened by Sensui. He is a student at Meiou Private Academy where he constantly attempts to outdo Kurama for top grades. He is a master of the written word, having written several books and enjoys word puzzles. His ability is "Taboo" which allows him to create word games that those within his territory must adhere to or their soul will be extracted from their body. While testing the limits of his power, Kaitou breaks his Taboo and has his own soul sucked from his body, prompting Kidou and Yanagisawa to consult Genkai to help him and explain their new powers. In the anime television series, Kaitou is voiced by Issei Futamata in Japanese and Jakie Cabe in English (Wiki).
