Action, Fantasy, Dark Magic, Reverse Isekai, Comedy One of my favorites. It’s rare to see a reverse Isekai this good. The ML gets transferred to another world by a priestess, lives there as a dark mage in order to change the public’s opinion on dark magic users. He achieves his goal and returns to his original world. Just to find out that monster gates appeared on Earth too and the military is struggling to keep the public safe. It’s very well told and I love the main leads personality. He’s so funny, and only cares about two things, his favorite video game character, and getting stronger.

Along the way, he learns more about his own past and the secrets surrounding his family's connection to dark magic.
