So overall I love the noblesse and I have read fan fiction of it being a crossover with vampire night, one punch man, and naruto. But I haven't seen one where Rai meet the guys in diabolic lovers or where he goes to the world of boku no hero academia. Even though I did mention I have read some noblesse fan fiction there isn't enough and I dont inderstamd why people dont make more noblesse and naruto or noblesse and one piece, but that is my own personal option because I only really have ideas on stories but I just can't write them so if you want more ideas or scenarios of what you can do with the noblesse just comment below.
