I don't own Naruto, Devil May Cry, or YuYu Hakusho.

On two worlds, there began two fights that will decide the fate of their worlds. On one world, the fight was random and unpredictable. On the other, the fight was passed down from father to son. At the same time, the fights are very similar. The fights are against two powerful creatures, demons. The fighters are trying to protect what they hold dear. The two major fighters both have a wife and newly born children, but that is were the similarities end. One of the fighters is a human, while the other is a former half demon turn full fledged demon. The human holds a post as the leader. The demon has to, as he would put it, 'clean up after his father.'

The world with the human leader

"Hokage-sama, the beast is closing in. What should we do?" Ask a man who is clearly on edge.

The man now defined as Hokage answered, "Hold the beast off when it arrives! Am I clear?!"

"Yes sir!" As the man finished, he disappeared in a swirl of leaves.

The man known as the Hokage was now contemplating what to do when the beast arrives. "This thing has no weaknesses, no remorse for its actions, and never tires. What do we have to do to kill it?" The Hokage asks himself. The Hokage summoned a messenger and sent a message to his wife to bring their twin son and daughter.

The world with the demon

Three grim reaper looking things rushed a man in a red trench coat with white hair and a giant broadsword. The man swung the broadsword cleaving two of the things in half. The last one jumped up over the blade. The man reached inside his coat and pulled out a gun. The man shot the thing twice in the chest and twice in the head. "Ah man, enough with these low-class demons. Come on out and show yourself Mundus, so I can finish what my dad started 2 millennium ago." yelled the man. The man turned to see two other grim reaper looking things jumping at him only for them to be cut to pieces by a blur. "About time he came, Vergil."

"Hmm, just be glad I decided to show, Dante. I wouldn't be here; if Mary (She finds out that her mother was the one who named her) hadn't begged me to save the father of her children." (Vergil's nature has changed after Dante almost killed him when he was Nelo Angelo) Vergil than turned and swung the Yamato. The demons that tried to sneak up on him were sliced in half. "Dante, why do you let Trish anywhere near Sparta? Every time she gets a hold it, everything goes straight to hell in a plastic grocery bag."

"What are you talking about? It is not her fault." Dante looked behind Vergil and saw Mary and Trish walking carrying Dante and Mary's twin sons. "What in the hell are the both of you doing here? Why are the two of you here? What if you die Mary? The boys need a mother."

Mary finally said, "The boys also need a father. You should think about that" Mary looked at Dante with a smug look to tell him that no matter what he said she was going to stay right there.

"Hey, enough. Trish said we would get a chance to fight some strong demons. So I unless you want me to take my frustrations out on one of you, lets found Mundus and kill him already," a man commented trying to annoy Dante.

Dante looked up to saw a group of men standing on the edge of a building. "Hmm, Yusuke is that you?" He disappeared and appeared right beside Yusuke, "Do you really think that you could handle a Sparta?" Before Yusuke could retort, a massive amount of energy was released, and portal that went to some other world opened up.

"Dante, do you think that is where Mundus is?"

"Yeah, Vergil," Dante answered; he then asked, "But where does it lead to?"

Yusuke said in an irritated voice, "Why does it matter? We need where Mundus is; let's go kill him." Yusuke was the first to jump through the portal; followed closely by the rest of the gang.

Back with the Hokage

In the Hokage's office, the Hokage, his wife, and their children can be seen. "Minato-kun, please to don't tell me you plan on using that justu. You know that you will die and I can't raise these two on my own," said a female voice.

Minato replied, "But if I don't, the people of this village with die; that includes us. Do you understand, Kushina? I don't what to use the justu as much as you do... but... it... What in the world is that?" He pointed behind Kushina. She turned around to see a portal open. An arm came out first, followed by the rest of the person. More people came walking out of the portal. When the portal finally closed there were ten people in the office, not including the children. Minato stood up and asked, "Who are you?"

Vergil stepped front and responded, "Don't worry about who we are. All you need to know is that we're here to kill Mundus."

"Yeah, and if you know were fuck he is? Tell us right now." Yusuke said, wanting to fight Mundus or one of his minions, but also forgetting about Dante's kids and not knowing about Minato's.

Before someone could get Yusuke to shut the hell up, a shinobi came crashing through the door. The shinobi appeared frightened and horrified. He finally said, "Hokage-sama, the Kyubi has breached our last perimeter, but it's not alone! A giant angel looking monster is helping it break through! We need your help!" The man passed out of a combination of exhaustion and blood loss.

Dante said, "So, that is he game. Come on, Vergil. Let's finish this." Dante and Vergil disappeared.

With Dante and Vergil

Dante swung his broadsword to intercept a punch threw by Mundus. Vergil was cutting at the legs of the Kyubi, trying to immobilize it. All attempts were proven to be fruitless. "Foolish brat, do you really think that you can harm me, the great and powerful Kyu..." The Kyubi's statement was interrupted blue beam to one of his eyes.

Minato, Yusuke, Kuwabara, Hiei, Kurama, Trish, Mary, and Kushina arrived at the battlefield. "ALRIGHT, DIRECT HIT!" Yusuke yelled. Yusuke jumped right into the fray only to be swapped away by one of the Kyubi's tails.

"Don't enter this fight. This one is mine." Vergil shouted at Yusuke as he regain his footing. Dante and Vergil tranformed into their demonic selves. Dante rushed Mundus only to be swatted away by the giant. Before he hit the ground, Dante disappeared out of view. He reappeared above Mundus and stabbed his broadsword, Rebellion, into one of Mundus's eyes. Vergil was repeatly disappearing and reappearing as he cut the Kyubi on it's legges, body, and head. While most of the wounds were heal, about 70, the rest were left open. Vergil quickly unsteathed and sheathed his katana, Yamato. The finally time Vergil sheathed his blade, an uncountable amount of cuts appeared on the Kyubi's body. The Kyubi became winded and envolped in a bright light. The light shrunk to a human sized blob. The light vanshied and a man in red Samurai attire, with twin katanas, appeared. The man reached for his katanas but was knocked back by a palm thrust from Vergil, no longer in his demonic form. The man tried to get up but fell back down to the ground in exhaustion.

"Fine, Son of Sparta," the man stated, "you win." Vergil walked over to the man.

"That is what you get when you team up with Mundus." Vergil looked over and saw Dante toying with Mundus. "Now tell me how a great demon like yourself ends up with a coward like Mundus." The man muttered something under his breath. "Hmm, what was that, Takahiro?"

"To kill you, Son of Sparta." Takahiro lunged but was met with Vergil ramming Yamato through his chest. Vergil watched as the life left Takahiro's eyes.

"So much for the great and powerful Kyubi," Vergil turned to watch the process of the fight between Dante and Mundus. He noticed that Dante was still toying with the giant. Dante floated atop a tree and surveyed the damage he had caused. Mundus's giant body had numrous cut and bullet wounds. Mundus opened his mouth and a beam blasted straight at Dante. Dante swung Rebellion and knocked it aside. Unknowing, the beam went straight at the group. Bodies flow all over; Trish and Mary were pushed into the surrounding forest. Dante continued to attack Mundus not knowing the damage that he had done.

Mary awoke and saw Trish laying a few feet away. She looked in Trish's arm and noticed that her child was missing. Mary, still child in her arms, ran over to check if she could find her other son. She looked around Trish and saw nothing. She tried hear her baby's cries but none came. She screamed her child's name, "KAZUMA."

The man, Minato, stood in the shadows holding the boy keeping himself unknown to Mary. Minato walked in the opposite direction. He glanced up and saw Mundus be enveloped in a bright light. He also heard someone shout "Mary" and "Trish" and the women ran off in the direction of the shout. Minato muttered, "You will make a great addition to Konoha."
