[Ah Ken]

I remembered watching Kamen Rider Kiva and also some horror movies that inspire me of doing this.
Here's the story: A long time ago, there was an evil warlock named Zlotan who was sealed into the underworld. 5000 years later, he decided to conquer the mortal world by creating monsters to terrorize humanity. Among the monsters he created were 5 who rebelled against him. In order to fight the warlock and his monsters, the team decided to enlist a paranormal scientist and monster hunter named Jeko to help them. Later on they were joined by a human monster hunter who is the scientist's son.
