Thank you for doing the research we all needed.

Check out dungeon crawler Karl and he who fights with monsters! Can also find them in audio book format 👌

The main character is a Japanese guy who's in Australia and the narrator of the audio book is Australian. The humor was on point for me and the magic and abilities that three MC gets are dark and horrific but he is such a funny silly guy it's hard to expect what he will do haha. Very fun story and cool abilities. Several books long as you won't be waiting years either 👌
