Aris Hausen is a shut in who skipped school and would played games all night long. He is living with his twin in the fair town of Linden. A simple errand outside of his house lead to his unexpected demise, when he tried to rescue his twin and her friend. After he died, a system announced that he crossed to Lamiales, a world governed with magic. Unfortunately, a guardian had appeared before him telling him that he died due to a mistake. The guardian was supposed to take the soul of the princess. Since, he could no longer get back to his original world, Aris was forcefully given the option to live in another world and to become someone else. Left with no choice, he was hurled into a world he only thought had existed in video games. When he came to, he became Aliester. The son of the Duke of Alcove who is on the run from pursuers. He thought he would lead a slow life in another world but instead he had to live on the edge for survival. Though he was not given any cheat ability, his system, Zarame is there to assist. Unfortunately, the missions that were a little too much to handle. "I am just a shut-in... why do I have to do this hard mode life?!" he inwardly screamed. And to add the cherry on top, he was given a special quest by the guardian... he had to be the one to make sure the heir would return and rectify the mistakes in that realm. Will this shut-in succeed with his mission impossible?
