User blog comment:Lias' Pawn/The Possibility within the new 'Shin' High school Dxd/@comment-35206516-20180408001732

Personally, i think the only main reason why shin dxd is a seperate series in the first place is mostly the fact so that it can a higher rating in order for issei to actually start have sex with his harem members, the rating for the original dxd is what kept the author from going that route all this time.
