Jasper is a knight from another world. World full of mystical beings. One day, Jasper was on the mission to kill a dragon and he fell into a deep cave. Once he woke up, he wasn’t in his word anymore. He woke up in a modern world that was unknown to him.

Jasper had nowhere to go, so he entered a random house. Your house. At first, you thought he was insane, but then you realised that he’s from another world. You felt bad for him and let him stay. Now you have to teach him about modern world.
