I don't know why you think he needs to hide his identity because mostly heroes do that which my MC isn't because if he does want to do something he will openly do it instead of hiding behind a mask. About bashing, I don't think I'll do characters like sirzechs or gremory bashing but I'll try to do riser, diodora or other villains bashing as they deserve it and there is already so much bashing fics on gremory that I'm sick of it. MC will have Ddraig but he will be able to customise the sacred gear in the shape of any weapon he likes such as a spear. He won't join a peerage because first he is a dragon and they are definitely prideful to lower themselves as servants and also he has no reason to become a devil. The MC is going to be super good looking but his lover or lovers won't just like him for that because I hate that kind of romance as there is no feelings behind it. About hiding his power, I don't think he should as hiding your power always pisses readers off as other characters mess and insult the MC and he just "hides" his power which I find irritating in fanfiction and animes so if someone messes with my MC he will shows who's the boss and show why is the dragon of domination. If I go the harem route then I'll save Kuroka and show the cruel side of the MC. The MC is not the original Issei so I don't think why he should be a pervert. If you read the status page in the auxiliary volume then it clarified that the MC is a genius from studying but I didn't make clear what he studied from the internet so as the fanfiction goes on I'll show more of his knowledge and intelligent side. Hope you read this.

Like what you say..as for hiding power....its fun if its done well...ex: Like in solo leveling....everyone thought he was weak but no one knew he was S rank? get it......basically its for face slapping moments......also I agree on the other ****..build romance..much better........keep him OP,,,....not pervert nice-why? that only works in manga and anime cause its funny,..reading in novels is just weird//get what I mean?.....also if MC is cold/cruel...dope..goodluck

I'm probably not going to be good at writing about an MC who hides his power but I'll make him have a calm and gentle exterior like a noble prince but also shows his cruel side with his enemies and don't expect me to spare any enemies unless they are necessary to the future plot.

eh....GL...just dont make it stupid like the others..yours is dope
