SO I am writing this after writing 60+ chapters and going to give my own observation on the fanfiction.
Mc : Pyro
System: gacha
Story is slow .
AI is used (only for grammar, atleast most of time)
You can skip GOT arc.
Suggestions: read reviews
Romance: no till 60 , don't know about future
R18 chapters: same as above.
Harem: hmmm yes I think so.
romance with Marvel characters: not decided, you can suggest .
Infact this ff was going to be a Pokemon collection adventure but somehow it didn't start till chapter 60 , atleast.
About my others FFs, while most are not updated but don't assume I have dropped them.
Oh , you can give some suggestions be it old or new reader .
