Hello again i'm still new to writing so please be lenient with me and understand that currently i suck but im still going to write stories because i loved crossovers and there are a lot of awesome story combinations that aren't done enough and i want to put some of my ideas out there so someone else can write them and I can read a good story.

I'm currently trying to figure out a writing style that I like that has a good combination of dialogue, imagery, and doesn't take an hour to write a conversation. Once I find one and get some practice in, I'll go through all the stories I have at the time and redo whatever I've done and make them better so you can actually understand what's going on while you're reading it.

I also need to actually watch dxd because a lot of the stories I'll make will be in that universe simply for plot and a premade world so I can't write anything if I don't know what is going on in the world everything happens in.

This is a crossover between dxd and a manga called 'White blood' or 'unholy blood'
Please read it, it's great story and fits really well with dxd

It was a week before school started, and the letter that had just been sent out to all the students and faculty had the whole school population in pandemonium.

Rias was curious about what the letter held but thought that if it was really important her brother would have informed so she had just thrown it in the trash but since she was now being told by grayfia ,her sister in law, that her brother was requesting her presence she absently thought that perhaps she should have read that letter and prepared herself for a lecture on throwing away important information and worrying about what she was supposed to know.

Just as she was about to ask grayfia what this was about, sirzechs told her to come in.

When Rias walked in she absently took in the amount of wealth in her brothers office which was similar to the amount in every room of the gremory mansion.

"So what do you think, Rias?" he asked while not really looking up from the papers in his hand. "About what brother?" "The letter, what else?" "Oh ahh that letter the school sent to everyone?" "yes." he said, finally looking up at her with a deadpan on his face. "oooh um-" "You didn't read it did you." he sighed while looking completely exasperated and like he hadn't slept in days which considering the piles of paperwork everywhere he probably hadn't. " Here, It's the copy I received." "how it got to the underworld I have no idea."

Dear Sirzechs gremory,
We are sending this to inform you that there is a new mandatory class for all years that as a second year Rias is required to attend. The board has come to the decision that with the outbreak in Korea that our students must be taught about this and the problems it causes. We have reached out to the only certified expert in the world, Miss Hayan Park, to teach this experimental class for the foreseeable future until someone else proves to know as much about it as she does. She is entirely in charge of the curriculum as she is the only one who knows what should be taught. And as such she sets all the requirements and course material for the class. Any attempts to get her fired for anything less than a serious crime will be immediately turned down as there is no replacement.

* There are no books required for this class. * Every Friday a randomly selected spokesperson will come in while Miss Park grades the tests you take every thursday.

Thank you for your cooperation,

Kuoh academy.

After Rias finished reading she kept asking herself if it was a joke and looked back and forth from Sirzechs to the letter waiting for him to say something. After about five minutes she realized that he was being completely serious

"Why are you asking me about this?" She was currently wondering about what could have happened in Korea that the school went to such an extreme as a new mandatory class.
"Rias no matter what you must ensure this class succeeds for the future of the supernatural world this is an important opportunity." "Why is this so important? It's just a class right?" "Rias It's what this class is teaching that's so important!" "Is there anything else? I need to go talk to my peerage." "Yes, no matter what you do, do not do anything to Miss Park, the gremory clan owes her a great debt due to a past dealing with her family, so don't try to make her a member of your peerage. Do you understand?" "Yes sir" "Fine you may go now.'' She then activated a teloportation circle to her room. After that she started searching the internet for what had happened in Korea to get a clue to what the new class was, after a few seconds she found out what the problem was and why it was such a big deal for the supernatural world.

The reason it was such a big thing to the supernatural world was because-
