Yeah, Racke has quite a few neat ideas. They're a 'he', I believe, though.
To be fair, many names are non-indictive of gender, so it's hard to tell when all you have is a faceless screen name.
And since I hate posting without contributing...
Making a Deal With a Devil by
EmeraldGuardian7
Summary: [ON HIATUS] After picking up a strange paper in the Department of Mysteries, Harry accidentally summons a devil to Privet Drive. Of course, this devil doesn't look at all how you might expect. She looks like a regular, albiet exceedingly attractive, girl. Their lives now tied together, how will Rias Gremory affect the war against Voldemort.
Review: A Harry Potter/Highschool DxD Crossover. This is a good read, though unfinished and hasn't been updated in ages. 5th Year Divergance for Harry Potter, pre-series for High School DxD and features MoD!Harry. Reasonably paced and a rare non-Harem fic- considering the Crossover material, though the author has said that they were considering expanding the main pairing, though leaning towards keeping it just Harry/Rias. There is groundwork for purely friendship pairings between Harry/Fleur and Harry/Ravel.
Wizard DxD Volume 1: A New Life by
bivz643
Summary: After the war, Harry leaves Britain for Kuoh to start a new life. While he may want to stay away from the holy war that is currently in a fragil standstill, how long will he be able to stay away from it all? Especially, when his title of Master of Death makes him a lord of the Underworld nobility. Also, what about Potters and their Redheads?
Review: Another Harry Potter/Highschool DxD Crossover. Harry Potter post-Series Divergence, though EWE. Highschool DxD Divergence right from the start. Another good fic and even complete, though the fic stops before the Rating Game between Rias and Riser. A Harry/Rias non-Harem fic, though future Volumes are supposed to expand on that. Sadly, no other volumes have been written.
FILFy Teacher by
Vimesenthusiast
Summary: A Harry Potter who has tried to take control of his destiny from second year on, finds himself in need of a fresh start due to his marital status changing abruptly. Armed with some abilities beyond the norm, a Mastery of Defense and a muggle-styles teacher's license, Harry takes his daughter, Lily Luna and takes a job offer at Kuoh Academy.
Review: Harry Potter/Highschool DxD Crossover with lots and LOTS of world building and character development. Harry Potter post-Series Divergent, EWE. Pre-series Divergent for Highschool DxD. Creature and Werewolf Harry. And while the pairing is Harry/Rias/Others, there is plenty of build up for that as well, as Harry has a very human mindset of monogamous, completely exclusive relationships that he has to overcome. Hell, he has to overcome the fact that Rias is his student before they start their own relationship. Once they do start dating, however, it's nice to see Harry and his daughter and Rias and her Peerage integrate into a close knit family unit, adding others along the way- and not necessarily in the romantic sense, as Rias takes on a motherly role for Lily and Harry becomes a father to Koneko, Asia and Kunou. Also, irregularly, for a Harem fic, not all of the women involved in the relationship are willing to sleep with the other women involved with Harry and all of the seperate relationships evolve organically in their own unique ways.
