I will not even attempt a JPN novel, honestly ive tried like over 50 and hated every single one of them. Read a lot of originals recently but if there is something that slipped by let me know, not particular fan of humor based novels but if its above and beyond then I will still try it out. Seems to be a pretty normal category of originals for some reason
well if you like darker superhero stories then you might like my story, The Vespidian. Though be warned Vesper(the MC) is a perverted weirdo. There is some comedy, though that is mostly to keep things from getting a bit too dark.
Would you like to try Monster Soul Online? It's Thai, so you might find it unique from what you have read. The early chapters lack originality that you are seeking, but if you keep reading, you will find that it is so original among all the novels of the same genre.
Try "Classroom of the Elite" its an Psychological LN with a lot of Mindgames, Climaxes and Twists. The start is a bit slow but still enjoyable ans the LN got 2017 even an Anime. There are 9 Volumes translated so far^^
