Sendou Jujutsu Resshi TAO

Tao is a young master of the Yin and Yang way, a hermit with unprecedented powers. Naturally nonchalant, nothing can destabilize him except his untimely sleep attacks: narcoleptic, he sometimes falls asleep uncontrollably. This is why he needs the assistance of Ranran, a medium with a strong character, as beautiful as she is fearless. Together, they sell their services to the highest bidder in a changing modern China. Divination, enchantment and the conjuring of demons of all kinds are the daily life of these two experts in Fangshu, the art of the Taoist mages. One day, they leave the Celestial Mountains of the Tian Shan region to head for Hong Kong where a mission awaits them. But an unexpected encounter will push them to travel across the seas to Japan, where striking spirits, demons and divine creatures are legion and could use a good lesson.
