Taijou Roukun

This ancient figure, one of the Three Great Sennin, embodies extreme indolence, spending most of his millennia asleep, only stirring briefly every three years. Due to a strong aversion to self-thought, he habitually communicates through others' mouths. To accommodate his laziness, he developed an almost unbreakable suit for sleeping, which regulates his temperature and provides him with air. He also established a unique connection with Yukyo through a bracelet, enabling her to communicate with him via hologram during his sleep. Furthermore, he serves as the mentor to Shinkouhyou.
