This was really a manga with a lot of highs and lows for me. Let me just say first that I liked the second half way more than the first half, though there is undoubtedly a charm throughout the whole story. The biggest strength of this manga is by far the art, Irie does a fantastic job bringing every panel to life and since our characters can use magic that means there's all sorts of fantastic looking sequences. For the most part the characters are great as well, and I really liked the developing relationship between Hibi and Ran.
So, elephant in the room. Outarou was the worst and he kind of ruined the early manga. Really the problem is that I think I'm supposed to find the scenes with him and Ran charming or romantic. Nothing could be further from the truth though, almost every scene with Outarou in it was just painful. I mean even if you ignore the fact that Ran is even younger than she looks, he STILL acknowledges that he's too old for her and goes after her with gusto anyhow. Even after he finds out she's actually 10 he doesn't even slow down, just keeps sticking his tongue down that throat. It's creepy as heck.
And honestly if he was the main love interest I woulda dropped this before the end more than likely
Using magic in your story is a double edged sword. On one hand, it allows for fantastic visuals and some very creative scenarios. On the other hand there's a whole lot of "uh, because it's magic" going on in the story. Magic is cool and all buy it does let the author be kind of lazy with the storytelling as a whole.
Three quick points:
1. They don't even explain the main antagonist of the series until it's been defeated. What the hell? It really felt like they should have explained it sooner
2. I didn't cry when Outarou died, I laughed because my dreams had come true
3. I was kinda hoping for just a bit more of Hibi and Ran in the ending. Heck, more of them overall. Sometimes I think that if most Outarou scenes were replaced with Hibi scenes this would be a better manga.
Overall I still give the whole thing an 8/10. Despite the flaws and the fact that I hated Outarou this was still an enjoyable manga once you got past the opening slump.
