There is a type of demon named "Gokusetsuma" which no one knows where they came from and what it is. One day they invade the human world and initiate attacks on humans for no reason…
Shinsei is a graffiti artist who loves Japanese Ukiyo-e style painting. He is also a Taoist sorcerer who knows how to use magic and spells, but he never reveals this ability in front of the others. He can also turn his graffiti painting into a real creature, however the painting will vanish after a life is given from Shinsei and it can only survive once.
Mei is the second generation of a rich family. One day he got a Taoist sacred object “Yellow belt of Tao” by chance. After he realises the true power of this object, he decides to use it as a weapon and associates with Shinsei to battle Gokusetsuma. Both of them later found out that Gokusetsuma were came through a portal from Hell which was created by an evil Taoist sorcerer. But the real reason for bringing them here remains unknown to both of them.
The battle continues and people around the world begin to realise there is a secret war going on between Shinsei and Gokusetsume, but still no one knows the true identity of Shinsei.
News travels fast on the internet. Netizen still have no idea who fights for them against evil. The only clue they discover is that the graffiti drawn by Shinsei always disappears with no explanation. In order to honour his heroism, the netizen gave him a name “BankXy of Asia”
