Taijou Roukun  

Roushi, 太上老君

Taijou Roukun, also known as Master Shinkouhyo, is a Sandai Sennin and the founder of Togenkyou. He raised Ryo Yuukyou and possesses several powerful paopei, including Ippakaseikunhaipa, which resembles a toy hammer, and his Taida Suit, which was designed to protect him while sleeping and supply him with oxygen since he is too lazy to breathe on his own. Despite being one of the Sandai Sennin, Taijou Roukun is incredibly lazy and spends most of his time asleep inside his Taida Suit, only waking up briefly every few years. He ultimately gives away his powerful paopei, the Taikyokuzu, to Taikoubou since it holds no significance for him or he has no desire to use it. Later on, he acquires the Keiseigensho from Dakki's possession.
