Chunibyo's Fanfic. (Currently in Highschool DxD.)

my writing style is very weird in the dxd world, as this is my first novel but I have changed it currently in the fairy tail world... so readers ? plz bare with it... I'm improving slowly on my writing skills with this novel and would love your response even if you are cursing or bad-mouthing me... but those curses better be meaningful ?... Unique Mc.... idiot Dragon inside Mc.... System..... Unknown Katana type.... Servants.... Harem.... now enjoy. Mc was born in DxD world. Currently in the world of Fairy tail... and yes there's something related to god too. I don't own anything used in this novel, other than the concept of my MC...and this Novel is for my personal satisfaction and a place for improvement...so don't mind it.
