A/N: Greetings! This is my try at an HP&DxD crossover. That being said, English isn't my native language, so if you see something that doesn't seem right, please put it in the reviews so I can change it. Also, don't hesitate to review if you have any criticism (or suggestion) to make. Just try to keep the review constructive so that I can improve. I hope you'll enjoy it, cheers!

A/N 2: I've read the reviews on Mixed Feelings, and I've got to say that I agree with you all; it was too short, which is why I'll endeavour to make this one longer.

Chapter 1

It was only a few days since his name came out of the damn goblet, and already, he'd had enough of all the whispers and scowls directed at him.

Deciding that he needed to go somewhere where he could plan in silence, Harry made his way toward the one place where he knew he would be able to enjoy complete silence: the Chamber of Secrets.

Arriving on the second-floor corridor, Harry looked around to make sure no one could see him, then opened the door to what was known around Hogwarts as Moaning Myrtle's bathroom.

Once inside, he went over to the sink that he knew would grant him entrance to the Chamber.

Just as he was about to speak parseltongue and consequently open the passage, a voice made itself known behind him, surprising Harry so much that he almost took out his wand on the intruder.

What prevented him from doing so was that he recognised the voice as Myrtle's, someone he considered an annoyance at worst.

"Did you finally come to visit me? I've been waiting for ages, you know?"

Harry figured that since he didn't want her to tell others about his coming here, he would placate her:

"I'm sorry about making you wait. I've had a lot of things to do and couldn't find time to come here before now."

"It's alright; at least you're here now."

"That I am. What would you like to discuss?"

"How about we talk about what you've been up to since your last coming here?"

"While I've had way too much school-related stuff to do, I sadly haven't been up to much that isn't related to boring classes." lied Harry.

"That's alright, thanks for taking the time to talk to me… You're the only one who has done so since we last talked, you know?"

"I'm sorry about that; I'll try to come and talk to you later this year. Unfortunately, I have to get down into the Chamber now, and I would appreciate it if you didn't tell anyone about it." Harry replied, feeling a little bad for her but, at the same time, wanting to get into the Chamber as quickly as possible.

"I won't tell anyone, I promise."

With that said, Harry looked back toward the sink and started speaking parseltongue:

"~~Open~~".

Arriving in the main chamber, he looked around and saw the basilisk carcass lying on the ground, looking exactly as it did two years ago when he'd slayed it. This made him wonder how many Galleons he could make by selling it to the goblins.

Deciding to ponder upon it on another day, he tried his best to clean his surroundings with the help of a couple of Scourgifys, among other spells.

While his efforts weren't useless, there was still a massive carcass in the middle of the chamber, so Harry conjured a bed in the corner furthest away from it.

While he usually wouldn't go to bed this early (it was only 8 pm), the fiasco that was his name coming out of the goblet and the events that followed had left him quite tired and, as such, he extinguished the various torches scattered along the walls and went to sleep on the conjured bed.

Waking up, he was quite surprised by the lack of snores he'd come to expect over the years of sleeping in a dormitory with four other guys as roommates.

While it was unusual, Harry didn't think it was worth worrying about. In fact, we could even go as far as to say that he was pretty happy about it. That is until he opened his eyes only to see a fucking 60 feet long basilisk lying so close to him that he could see it even though he wasn't wearing his glasses.

While anyone else would panic and scream in fright, this is Harry Potter we're talking about, and, as such, his reaction was that of someone much braver; he took out his wand from under his pillow and ran into the nearest hallway, trying to rein in the little voice in his head urging him to take on the creature in a glorious battle to the death.

When he was sure that he was far enough away from the beast, he looked around and was surprised to see an old-looking wooden door at the end of the hallway. Attached to it, there was what seemed like an old portrait of a sleeping man that Harry recognised as Salazar Slytherin.

Intrigued, he approached the door and tried to open it; it didn't work. Using Alohomora didn't either, and it took Harry two minutes of intense thinking to realise that speaking parseltongue might be the key to opening the damn door. Though what the parselword(1) was, Harry didn't know.

He doubted that a simple "~~Open~~" would open the door and, as such, he tried to use the same thing that this random dude named Tom had used to open the mouth of Salazar's statue when Harry was in his second year:

"~~Speak to me, Slytherin, greatest of the Hogwarts Four~~".

Salazar Slytherin apparently was a man of little humbleness as it worked, and Harry was granted entrance into the room after receiving what looked like a terrible attempt at winking from Salazar's portrait.

Walking in, the first thing he noticed was how dusty the room was. The second thing was that it seemed void of anything other than a worn-looking book lying on a golden altar.

Approaching it, he could see that it was written in what appeared to be weird, unintelligible symbols. While he couldn't understand any of them, there was the little voice inside his head going at it again, telling him that all he had to do was to hiss at the book to reveal its secrets.

Deciding that he had nothing to lose doing as it said (unlike last time), he gave it a go:

"~~Reveal your secrets~~".

It took about 5 seconds before anything happened, but when it did, a bright flash of light forced Harry to hide his eyes with his hands.

When he opened them again, he noticed that the text was now legible. Silently thanking what he was now thinking of as his guardian angel, he looked at the book's title:

The Only Ritual You'll Ever Need

While the name made Harry cringe inwardly, he supposed that he should still read it because, if he was to be honest with himself, he had nothing better to do, and it might prove helpful.

It took Harry an hour to read all about the mysterious origin of the ritual depicted in the ancient book, its uses through time (it had only been used twice since the family of both of the users had never heard back from them) and how it came to be placed in this exact same room.

The only thing that wasn't explained was what the ritual actually did. As such, the only valuable things that Harry knew were how to do the ritual and that it would help him out of any problem in exchange for an unknown favour. Though to whom he would owe the favour, he didn't know.

The ritual itself seemed easy enough; he would have to draw some strange symbols with his wand while chanting in parseltongue. The only problem was that he would have to do it on yule and, because of that, miss the yule ball.

While not going to the yule ball would most assuredly get him in trouble with the professors, it was a small price to pay, given that he wouldn't be able to find a date that would want to go with him without any ulterior motive anyway.

Sure, most of the students didn't even know that there was a yule ball yet, but that didn't stop some of the girls from sending flirtatious winks Harry's way, perhaps hoping to profit from his fame.

When it is announced that there is a ball and that the champions are forced to bring a date, even more girls and maybe even some boys will try to get Harry to choose them as his date.

Of course, each will have various reasons for doing so, but, in the end, none of them will be genuine in their intention to have Harry as a date.

This is why Harry decided that on yule, instead of going to a silly ball, he would do the ritual, and who knows? He might be able to survive through this year.
