Most novels on this site feels like it was written by an 8th grader because it is poorly translated. The translations can make and break the novel for me.The best novel I've read so far is Dungeon Defense. Hell, you would not even know that the other was korean if not for all of the pop culture references. The translations were that good. I also really hate when there is author notes in every chapter for a novel. Author notes have a bad habit of explaining the reasons of why a character did something. A good novel makes it blatant of why a character did something through build up and foreshadowing and not with Author notes(*cough*Absolute Choice*cough*EER*cough*). Here are some other novels that I highly recommend that fits this criteria- Akuyaku Reijo Ni Koi Wo Shite Overlord(ln) Release that Witch Thanks for the Help!
All novels from Eat Tomatoes especially Coiling Dragon and Stellar Transformations both are translated Another good novels Tales of Demons and Gods And if you liked Dungeon Defense you will love Dungeon Hunter too one of my most loved novels
Most things translated by Untuned Translation. I recommend Allison in particular (and its sequels and side-stories). No translation notes or author notes, and if it wasn't for the art, you could probably go through the whole novel without noticing that it's Japanese.
The Girl Who Ate a Death God Or additionally, go western. http://forum.novelupdates.com/threads/stuart-slades-the-salvation-war.5630/ https://parahumans.wordpress.com https://practicalguidetoevil.wordpress.com http://hfy-archive.org/book/deathworlders
Lord of the Mysteries (Masterpiece) Reverend Insanity (Not my cup of tea, but I do undoubtedly agree that it's a very good novel.) Nirvana In Fire ( I mean..it is also a TV series, after all.)
