to be honest I would have wonder if your character would have been interesting if he ever interact with the three protagonist and above all Sakura who would have be the niece when your own character was still alive. you know the "what if,s" if he ever influence them to change there path.

I'm talking about the Naruto cast. it's nothing against your character, the story you make us alright. it just feel sad that their life ended so soon.

it's best this stays discontinued so it save us a lot of heartache for main characters. though the story turn out alright but the OC never actually have a proper ending to begin with. but also sad the MC have to be killed off just to fill the OC for more power. but still good story, not one I'll appreciate though
