Madan no Ou has a completed preview of the 1st and 3rd novel already at BT. I've read the first one and it really does have a good story. I don't see how the MC is OP though. If anything the Vanadis are the ones who are truly OP.
Sorry again for adding to the list, but you're the only one left with this. Please reupload when you have the time, thanks. みずカノ
Also, could you update this to Ver1.31? It wasn't listed, but it definitely got updated. 隷属と解放のラビリンス
