Episode 1: To the Depths of Hades

Author's notes: This is a crossover between Disgaea 4 and Rosario + Vampire. The story occurs somewhere around the ending of the main Disgaea plotline however there may be some timeline distortion. Seeing as this is a Disgaea related I'm surprised I'm not making them break the 4th wall. I'm also using youkai when the story referring to or in the Rosario universe and demons when referring to Disgaea. Also somewhere in the middle I got too lazy to use proper quotation structures for sentences so I'm just going to put the person's name before or after what they say.

Aono Tsukune was just an average boy in high school. He was unexceptional at everything he did. Because all the other high schools did not accept him his parents found an ominous flier for Youkai Gakuen.

Basically he enrolls in a school for monsters with him being the only human. He meets a very cute and attractive vampire named Akashiya Moka. During their school days they faced many obstacles and made many friends.

However after delving into Moka's rosary seal and learning about her past Tsukune finds out that Moka is the key to awakening Alucard the legendary vampire. In the present her eldest sister Akua Shuzen captured her and took her to Fairy Tale's HQ where she is held to eventually awaken Alucard.

When Alucard is awake the world will end and the humans will be annihilated. Tsukune hating his self weakness decides to train with Touho Fuhai one of the 3 Dark Lords.

After undergoing human modification Tsukune can now use youkai techniques and control the vampire powers he got from Moka. Now this is where the story begins.

Tsukune was sparring with Touho on his 1st week of mastering his new modification. "Too slow brat!" Touho instantly evades and counters Tsukune's punches and lauches him to the wall shattering it.

"This won't do. This won't do at all. I know we still have time before you invade Fairy Tale but at this rate you will never be able to see Akua let alone fight her." Touho stated in a condescending yet concerned tone.

"I have to get stronger. This is not just for me or Moka. This is so that I can protect everyone." Tsukune said that as he got up. Observing his resolve and determination Touho came up with a brilliant idea. "I know a place where you can train and test the limits of your strength." Touho said to Tsukune.

"Really?" Tsukune wondered. "It's called the Netherworld, more specifically Hades where human souls go to atone for their sins. Normally you can not enter the netherworld unless you are dead and went to atone however I can make you an exception.

"Huh? I'm going to hell to train? Are you sure you head still works?" Tsukune responded puzzled. "You better watch your head where you're going." Touho replied. "I will open up a dimension gate to the Netherworld. You will then enter and meet with a demon named Valvatorez.

He will train you and even though this is very serious, have fun." Touho reaches his hand outward and a portal appeared behind Tsukune. "Train hard boy." Touho kicked Tsukune into the portal and here Tsukune falls into Hades.

"Ahhhhhhh" Tsukune screamed as he hit the ground hard. When he looks up he sees that he is not in the human world and in a world ruled by demons. He finds himself in the main lobby of Hades the Netherworld's great prison and factory.

"Hey it's a new recruit." said one of the demons at the desk. "You're here to become a prinny and work hard to atone for sins. Now into the factory you go to be processed into a prinny."

Tsukune tried to back off but he was quickly grabbed with brute strength and taken to an assembly line of some sort. There he sees that a bunch of penguins with bat wings are being manufactured at a rapid pace and the souls being put in them.

"Hey, I'm not gonna be like them am I?" chuckled Tsukune lightly with fear leaking out. "Don't worry it wont hurt a bit." the demon remarked sinisterly as he throws Tsukune into the assembly line.

Tsukune was being drawn into the machine and when he entered it he felt strange. The feeling was like his body stopped being his own and replaced by another.

Knowing that he cannot allow himself to be turned into a stuffed penguin Tsukune unleashed his powers and started destroying the machine from the inside. The device exploded causing a mass of prinny hides to be blown all over the factory.

"What is the meaning of this! Who dares cause a disturbance in my Hades?" a voice shouted. The voice was very strong, loud, yet dignified with all of it force felt by Tsukune.

Just then a person wearing a black suit that is quite original with a cape approach Tsukune. He does not look happy. "Hey! Are you the cause of this mess?" the person inquired forcefully. "You know that the machines here are expensive and are not easy to replace right?

"Time for me to reeducate you through my horribly painful rehabilitation!" Tsukune pleaded waving his hands to stop, "Please this is not what it seems I have no intention of fighting you.

I'm umm looking for someone named Valvatorez. You know where I can find him?" The person responded, "Yes, I'm Valvatorez state your business and be on your way." Valvatorez did not seem like he was in a good mood after having his production line destroyed.

Tsukune explained that he was sent to the Netherworld to train with Valvatorez and afterwards he was taken to Valvatorez's room. The room was small, simple, had a coffin in the middle of it and other junk stuffed in boxes around it.

"So you want my help to become stronger?" Valvatorez said in a condescending tone. Well of course he would. "Don't waste your time training a weakling like him my lord." a voice called in the shadows. "Fenrich, you're back. Did you get my next batch of sardines?" Valvatorez answered his servant.

The servant, Fenrich nodded yes to his lord. To Tsukune they looked like normal people however he knows that they are hiding their true powers.

As much as Fenrich would prefer Valvatorez does not train Tsukune. Valvatorez owes a favor to the 3 Dark Lords in the past, but that is a story for later. "Fine, I'll train you to be strong enough to face Alucard." Valvatorez.

"Really? But I only have around 1 month before I go." Tsukune said disheartened. "I promise that I will make you strong enough to protect the ones you love. That is my manifesto as a proud demon of the Netherworld." Valvatorez said his encouraging speech.

Fenrich scolds Valvatorez for making another careless promise. Tsukune learns from them that time flows differently in the Netherworld. Years can pass here before a month passes in the human world.

Of course this depends on how isolated the boundary between the worlds are. "Your training starts now." Valvatorez hands Tsukune a scrub and orders him to scrub the toilets. A level 1 prinny task now assigned to him Tsukune starts working hard.

So begins the trials that one man must face for love, for friendship, and for his harem to be complete.

-To Be Continued

Leave a review please no flaming or hate. I'm open to new suggestions about my writing style and how I can improve. Btw the next episode segments of the other episodes do not reflect what happens next. Like the Disgaea series it is there for comedic purposes. Except when the final episode is coming.
