Taijou Roukun

One of the Sandai Sennin(Three Great Sennin). He has lived over a thousand years,however he is extremely lazy sleeping his entire life only waking a brief time every three years. He hates thinking and using his own mouth so he will usually talk by using the mouths of others around him. Because of his laziness he has invented a suit that's nearly indestructible which he sleeps in to moderate temperature,protect his body as he sleeps,and breathe for him. Somehow he has managed to raise Yukyo, a relative of Taikoubou via a bracelet he gave her that allows her to speak with him via hologram, but it only works if Roushi is experiencing REM sleep. He is the mentor of Shinkouhyou.
