As quite a few of us surely know Highschool DxD is a nicely drawn anime featuring lots of fanservice with gorgeous girls, interesting weapons like sacred gears, and a pretty decent plot.
There are so many twists and turns you could tweak this story to that it's amazing that there isn't a ocean of hentai fanfiction for this series instead of the 4 or 5 on this site and I think I saw 3 others on another making it simply 7-8 in all. So, it has come to my attention that I must try to do something about this
Thus the creation of this new forum where we can spout whatever lemon ideas whether it be vanilla, chikan, netorare, or whatever. Hopefully this will fuel some much needed creativity for this series and inspire a wave of stories for it or at very least we can all have fun talking about this and that scenarios.
Okay with that said, let me get started.
Essentially my idea to get things started off is this. As was said in series Rias was originally engaged to Raiser Phoenix who is kinda something of a narcissistic asshole. She accepted a rating game to determine her fate despite the fact that Raiser had a complete peerage, experience in playing rating games (did 10 games), phoenix tears (not to be confused with Phoenix down lol, anyway think of them as red potions that fully heal health), and of course Phenex clan ability of them pretty much being immortal with only way to take them out is to either wear them out mentally (easier said than done) or use a almighty hit to extinguish them (again easier said than done).
Rias does not have a complete peerage her team consists of only 1 rook, 1 queen, 2 bishops (but only 1 is available as other is sealed away), and 1 knight. (taking out Issei to make it more of a longshot but if you want you can add Issei)
Rias thought she could close the gap between her and Raiser despite the fact that they are outnumbered more than 3 to 1 with just some simple planning and week worth of training (yeah... naive much).
Anyway Rias gets some news that Raiser isn't sitting on his ass like she thought he would and is actually training for this match as well as assembling his resources. Thus she is forced to admit to herself that what she is doing in preparation is not nearly enough. She can't go to her family to break off engagement as they are all for it supporting it and is thus pretty much left on her with her peerage to get her way out of it.
Anyway she needs to look for a way to get a decisive advantage over her fight with Raiser so she won't be stuck married to him for 10,000 years. Still things go on, and she is called for a contract which she accepts to take her mind off of current state of affairs. It is there however she finds that magician that contracted her (can be young or old up to you) has exactly what she needs to negate advantages of both phenex tears and phenex regeneration.
Basically a legendary weapon that causes injuries to be unhealable unless sprinkled with a very specific remedy which is part of weapon (it can be anything you guys want) itself. She tries to negotiate for it but fails. It is a priceless treasure after all, its not like it would be that easy. Still guy makes her a offer to give him spear if she would be his slave for a year and do whatever he said. As you can imagine Rias would of course object to it and leave but he would say some words to make her think.
Devils live for a abnormally long time around 10,000 years, would it be better to be miserable for 10,000 years with man she hates or simply be forced to deal with similar situation for year. Thus she ends up agreeing to conditions signing magically binding contract saying she will do all he says, and won't seek payback or retribution when its all over she signs it albeit extremely reluctantly and because of it she was barely able to win rating game and thus cancel her agreement. Still there is another agreement that Rias has to fulfill.
Also thought of Akeno finding out about this and offering herself to take Rias place and things get worked out in which she ends up joining Rias but time frame was chanced from year to 6 months.
Thus you can have OC do whatever you want to these lovely voluptuous devils
Okay, lets hope you guys have thoughts of your own and take interest in this:)
