I just discovered that this series has a manga yesterday. I don't know why but I find the manga less enjoyable. Maybe because the web novel delivers the story more slowly to the reader. The story's comedic punchlines felt more natural and less anime-ish.
For the manga-only readers, in case you're curious. The manga is barely halfway of the web novel. So expect more to the story.
Also, the web novel is in hiatus. I heard that the author is focusing on the LN and manga to catch-up but I could be wrong.
