Be a Brave Man with a Black Cat

Go forward, the goal is the stars and the sea. If you encounter treasures, take them all away. If you encounter monsters, use magic to hit them. Burn them all~rob them all~and commit all kinds of evil. Forehead! The lines were not quite right, it seemed like I was on the wrong set. In short, it's a simple story about Link, a novice mage, going on adventures. But at what point did people around him start calling him the "Black Cat Brave"? If you are tired of watching the plot where the protagonist hacks and slashes alone, then come here to watch the plot of a group of people hacking and slashing.
