Can someone recommend me a novel that gets funny as hell, but when the time comes it could become a massive onion cutting machine? Just like "tomorrow i will die, you will revive". I don't mind if it's R-18 as long there's a great plot in it.(sorry for bad english)
Sevens is seconded. Much laughter and Seriousness to be had. The ending scenes is just the most cathartic scene of all.
I Shall Seal the Heavens. It is a novel which induces the height of emotions, whether it is adrenalin from the action packed sequences, laughter from the many comedic scenes, frustration at the MCs blunders or sadness from the poignant "feels" scenes. I highly recommend it if you want a multi-faceted novel
The Experimental Log of the Crazy Lich Edit: you haven't read tragedy + comedy if you haven't heard of this one.. it's beginning is a bit slow but it starts showing it's true value from chapter 60 onwards... it's almost a feel train in some chapters.
How about dark fluffy? Demon Girl ~Tale of a Lax Demon~ Ascendance of a Bookworm - Has both comedy and tragedy Arena - This is suppose to be tragedy and comedy but not sure I follow the comedy (Though it is very good read)
