AN: For the record here, I own absolutely nothing by Namco Bandai games, NIS America, Nippon Ichi, and any other companies I haven't mentioned. That means I do not own any characters mentioned within the story, the plots, and what the characters say except for my own. Aside from that, enjoy my first actual crossover fan fiction…

What Went Wrong?

A Tales of Symphonia: Dawn of the New World and Disgaea 2: Dark Hero Days fan fiction.

Chapter 1: The Other Dimension

"Wait a minute… that smell… Decus is here?" The young, blond haired swordsman spoke, covering his nose because the overwhelming stench of what was thought to be cologne came to his senses. He wasn't the only one who covered his nose, a brown haired young lady, a blue-haired duke and former convict, and a black haired kunoichi and summoner were covering their noses as well. They pressed forwards, lightning striking the land around them, even though they were inside a temple, and saw a man with an iron maiden, trying to press on through the temple, but a female researcher was blocking the way.

Decus, the man who the blond named Emil had mentioned moments before, was trying to get past in search of something that was really important to Emil and his group, currently consisting of Marta, the brown haired lass, Regal, the blue-haired Duke and owner of the Lezereno Company, and Sheena, Mizuho's klutzy assassin and summoner. A dark dog spirit, Centurion Tenebrae, was with them as well, and he was the Centurion of Darkness. The group was currently on a quest to awaken the Lord of all Monsters, and former Guardian of the Giant Kharlan Tree, Ratatosk.

"I don't want to kill you, but I will if you don't move, young lady…" The purple-haired man, Decus, spoke to the researcher, but she was explaining how the path ahead was quite dangerous, though he refused to hear it. Emil wanted answers on who he really is, if he was a boy named Aster, or if he really was Emil, so this researcher had to live.

"Decus!" He cried out, rushing up behind him, his hand on the hilt of his sword in case he needed it. The man turned his head to look at the boy who had interfered a few times before, and didn't expect him to interfere again.

"It's you again, but I know that as you are now, you can't beat me…" He spoke, or rather, that was the point he was getting at, since he said more. His iron maiden opened up, and Decus reached for the sword he uses which was within it. Emil drew his sword, just in time to block the swipes that Decus was giving him. "Hahahah! Without Ratatosk, you're just another punk kid…" He taunted, and Emil knew he was partially right.

Everyone else wanted to help, but Emil was speaking to the other self, the one who was always prepared for battle. "Help me… I need you, my other me…" He spoke within his mind, and it wasn't long before he received a response.

"Make me do your dirty work… You always have to call on me when you can't do things yourself…" The voice spoke, and Emil's closed eyes slowly opened. His expression had completely changed from a timid young lad, to an intense fighter's face. And his eyes, no longer the innocent green that they were before, but now at an intense crimson that showed anger.

"Gate to the dark abyss, open!" He commanded, opening up his right hand just after sheathing his sword, after Decus was exhausted from swinging his blade. But before Decus could get in a blow, he and the researcher were pulled into the portal that opened behind them. Once they were out of sight, "Emil" realized something wasn't right, when his black scarf began to flutter toward it. "What… impossible!" He exclaimed, and before he could close it, he was being pulled by the gate's gravitational pull.

"Emil!" Marta cried out, and wanted to help him, but Regal restrained her from being consumed by the portal's pull as well, as Emil was left fighting against the gravitational pull of the portal.

"This is absurd; it is impossible for the user in possession of Lord Ratatosk's powers to be affected by the ability as well!" The dark dog-like creature, Tenebrae explained, and before everyone realized it, Emil was dragged into the portal, holding his hand out before eventually closing up with him consumed by it.

"EMIL!" Marta cried out, tears welling up in her eyes when the one who she had loved was gone before her. Though he was complicated to figure out, she still loved him, whether he was in "Ratatosk Mode" or as himself. She had broken out of Regal's restrain, and went over to where the portal once stood, falling onto her knees. She was crying her heart out, because she swore to herself that she wouldn't love another.

"Tenebrae, do you know where that portal took Emil?" Sheena asked the Centurion, but he couldn't give a straightforward answer.

"The portal that Emil opened up sends whoever is in possession of a Centurion's Core back to their respective area. But as for Emil himself, he could've been taken anywhere, since Ratatosk has the power to send anyone, including those serving him, to any point in time and any dimension he desired. So for our hope, Emil has to either be here where the Centurion's Core is, or the Earth shrine, since we haven't obtained Solum or…" Tenebrae exclaimed, but Marta was more interested in finding Emil at the moment than any Centurion Cores.

"Let's hope he's up ahead…" She spoke, and Regal and Sheena agreed, and they walked by her, with Tenebrae following, but Marta was held back. "Oh Emil, please be safe…" She prayed, before rushing to catch up with them, hoping her love would be just ahead…

~Meanwhile, in the dimension of Veldime…~

"So you're sure that this summon is going to work, right?" The red-haired battle maniac spoke, his eyes looking as though he wasn't quite convinced. Adell was this young man's name, and he was a Demon hunter who has yet to lose a fight with anyone. Standing in front of him was a purple haired, three eyed demon, who was his mother.

"Stop complaining, I'm sure that this summon should be able to call the demon you're looking for. You better be thankful that this summon is far simpler than what we had to do last time…" She exclaimed, looking at the blonde-haired woman several feet from Adell, who wasn't at all impressed with being here. "Hopefully you'll get the result you're looking for, which is Overlord Zenon, right?" She added, and Adell gave a sigh.

"Fine, but if it fails, I'm not coming to you to attempt to summon him again, okay? I'm tired of looking around for materials required for summoning, and be glad that this summon doesn't require life to work… It would only be easier if I go around looking for him, rather than summoning materials that may or may not summon him…" Adell sighed out, and the blonde-haired woman who was wearing an extravagant dress for any demon, just "Humphed!" in the background. This demon was Rozalin, and she was this Overlord Zenon's only daughter, or so she proclaimed.

"Alright, well on with the summoning… Be sure you're ready Adell…" She spoke, pulling a summoning flute from her side, as Adell got into a fighter's stance. Adell's mother placed her lips against the flute, and began to play, lights starting to form around her, and the pot that was only a few feet away. She played the flute for a while, and eventually, she had to complete the spell.

"By the power invested by me, and in the name of Adell, I hereby summon the strongest warrior in the world!" She cried out, putting the flute aside, and the summoning pot before her began to glow brighter. Adell hoped that this summon worked, and Rozalin was just as eager to see what would come out, hoping it would be her father. But, something did happen, a blond-haired figure flew out of the pot, and high into the sky, right towards the sun.

Because it was towards the sun, Adell, Rozaline, and everyone else was blinded, so they couldn't see the figure perfectly. "Is it him- Oof!" Adell spoke, before the figure landed right on top of him. The character seen before them had blond hair, like Rozalin's, and he wore dark clothing, so it was questionable that he may have been related to Rozalin. However, he seemed too young to be Zenon, and Adell's mom knew it.

"Awww, what went wrong this time…?" She asked, looking a little disappointed, as Adell pushed the lad off of him, and moved over to the side to get a better look.

Like he expected, the summon had failed, and he sighed. "I knew I shouldn't have relied on you, mom… Now instead of Zenon, I got a human here who has some very bad luck." He explained, rolling his eyes, though the boy didn't stir for a while. His clothes were definitely different, as if screaming out that he was an overlord, but this lad was the boy who was consumed by his own portal, Emil Castagnier.

It wasn't long before he began to get up with a groan, and his mom sensed that the boy was indeed human, but he was by far different than a normal human, or Adell. Emil opened his eyes and looked around, not even paying attention to his surroundings and who was there. Emil was back to his normal self, since the other him didn't want to be the one who was to hurt later.

With a silent groan, Emil had had managed to get to his feet, looking around at the village which was known to Adell as Holt Village, with everyone looking at him. "Ohhh, my head…" He groaned out, and turned around to face the red-head, who had an eyebrow raised. Emil was shocked to see the redhead, almost seeing another from his figure.

But everything that Emil saw wasn't from Aselia, or anywhere that he has been to. "Ummm, do happen to know where I am…?" He asked a bit nervously at the similarly aged young man, and Adell looked at him with a quizzical look.

"Oh, you're in Holt Village in the world of Veldime. Normally, this would be human-populated, but due to a curse from her dad…" He spoke, signaling over to Rozalin momentarily, "Everybody except for me has gained some monster-like traits… But you're human too, and yet you're not affected by Zenon's curse… Why is that?" Adell spoke, looking at the lad. Emil was confused with everything he said, because he never heard of a world called Veldime, or a village by the name of Holt. And that humans had some monster-like traits, Emil was a little off guard.

"What…? Sorry to say this, but I've never heard of such a world called Veldime, or even a village called Holt before… Would you mind explaining to me what is going on here? And is there a way for me to return to my world…?" Emil explained, and it was Adell's turn to be confused, at least when Emil said that he came from another world, more or less.

"Ummm, mom… I think you're summoning skills have gone a bit too far this time… But if you said to summon the strongest warrior in the world, why is it that this warrior is level one…?" Adell asked, and Emil was confused when he brought up the words of "level one".

"Level… one?" Emil asked, having no idea how this world works compared to his own. Adell sighed, before taking the boy by the wrist and dragged him inside, with everybody following behind the Veldime warrior and the newcomer, to get the lad up to speed with what was happening…
