Review Detail of StarWriting in Second Journey (Highschool DXD Fanfic)

I'm giving an honest review here, this story isn't readable in it's current form. There's a grammar error almost every sentence that just makes this not worth the effort to read. Also you having an OC just follow along with the general dxd plot and change nothing is pretty much the absolute lowest form of fanfiction there is. It's like reading one of those aweful naruto fanfictions where someone will add a forth member to team 7. No one wants to read that...That's what you're doing here.
