Dark Crossover

There seem to be a disturbance coming from outside the walls so the Survey Corps decide to find out as they used their Maneuver Gear to investigate. It was then Eren Jaeger discovered an outsider that wasn't from this world. He had white hair like ivory, he wore black, and a mask. Surely, this was something that Eren had never seen before! "Who the hell is this guy?" Eren wondered. He went down there to confront the guy, ignoring the squad calling out to him. He had to know who this person was and where did he come! Eren had his blades ready as he faced the person. "HEY!!!! HOLD IT RIGHT THERE, ARE YOU A TITAN OR SOMETHING?!" cried Eren. The white haired guy didn't answer, he looked like he was in his late teens, maybe older than Eren but he looked younger. Although by his serious looks, he seemed to be mature. "Who are you?" Eren asked. Still no answer. The young man with the white hair stopped and looked around, "I don't think this is my world, isn't it?" He asked. "No, it isn't. Where did you come from?" Eren said. "I'm Kaneki. Ken Kaneki. I don't know who you are but you're in my way." Ken said, he unleashed his kagune. Eren was horrified by this sight as he defended himself against Kaneki and his kagune! As it seemed, Eren knew that this Kaneki guy was pretty strong! But he wasn't going to give up without a fight! He clashed with Kaneki as everyone of the Survey Corps cried out for Eren's name. However Kaneki managed to strike a hit on Eren, giving him a bleeding cut and Eren felt some sort of flash as he screamed. Ken watched as he backed away to see this soldier of a boy has turned into a giant. A raging, malicious and psychotically vengeful Titan. Kaneki tried to fight back against Titan Eren but yet, it was hopeless! He used his kagune with all his might however the roaring Eren did not ceast and defeated Kaneki. Kaneki was alive but he was injured. The only way he could heal is that he must eat....He then grabbed onto the skin of the Titan and chomped at it. Titan Eren cried out in pain as he smashed Kaneki all around and finally managed to get him off his leg. Kaneki licked his lips, "You know....For a monster, you taste pretty good...A bit strong but really good." He noted. He managed to escape into some iridescent light as Titan Eren followed! Everyone was blinded by the light, they were shocked to see that they were both gone and wondered where they had gone. Mikasa and Armin were concern for wherever Eren might be!

Meanwhile....Yuu & Mika were facing off against the monsters known as Four Horsemen of John, they were clashing with it as the monster was attacking but Yuu and Mika dodged it. Yu had his weapon, which was a Cursed Sword, as he used it to take on the beast! The beast managed to get the upper hand as he took down Yuu, who went down tumbling. In retaliation; Mika try to assault the monster! But he was knocked backwards right next to Yuu, they both looked like they were about to be beaten until someone step in and punched the monster back! But this someone was a human. This incredulous Yu and Mika as they watched in disbelief at the sight of a human but he wasn't an ordinary person at all! "Who was that, Yuu?" Mika asked. "I don't know!" replied Yuu. They watched as a boy who looked to be 16 to 17 was fast as he used his skills and his hand became a weapon out of a muscular-like transformation. There was an eye on it, Yuu and Mika were taken aback by it! "Shinichi! I believe we have witnesses in the battlefield!" A voice said, coming from the hand on the right. Yuu freaked out: "The hand! His hand talked!" He cried. The hand came to life but the boy scolds at it, "Migi! Not now! We don't have time!" Yu called out, "Hey! Did your hand just talk?" The boy looked back with a calm, blank expression. "Yes. You never seen a Parasyte before?" He said. Yu looked perplexed, "What's a Parasyte?" He asked. "I don't think you would understand what it is." Shinichi said. The right hand showed two eyes and a mouth, "It appears that you two are different species...One is human and another has some sort of supernatural tendency over them." It said. Yuu trembled, "Is that what you call a Parasyte?" He asked. "Uh, yeah....I call him Migi. I'm Shinichi Izumi." Shinichi said. "Uh, I'm Yuuchiro Hyakuya and this is my friend, Mikaela."  Yuu replied. Mika then spoke out: "Behind you!!!!" He cried out. However Shinchi already knew because he took on the Four Horsemen of John with his power and his Parasyte sidekick! Yuu and Mika helped out the strange guy by working together with him. It wasn't going to be easy dealing with this guy and the fact that his arm was alive! However, all three--with the inclusion of Migi involved! Once the battle was over; Shinichi seemed calm and not so exhausted. Yuu was amazed as he try to catch his breath. "How....can you...be so...calm....?" He gasped. Shinichi looked at him, "I'm not human as I used to be." He said. Mika glared at him, "Are you a bloodsucker like me?" He demanded. Migi appeared, "A bloodsucker?" He asked. Yuu looked at the thing with disbelief, "You're little friend doesn't know what a vampire is?" He asked. "Apparently not, but he is by far a fast learner. Maybe you can explain it to him but for now, let's find some place out of here." Shinichi explained. Just then, there was a bright iridescent light that blinded almost Shinichi, Yuu, and Mika. What happened next is something they will never forget! Eren and Kaneki woke up in a desolation place of building and monsters all around when they came across a boy with spikey hair who looked normal however he had a calm persona and a hand that comes to life. There was a boy one year old than Eren, he had dark hair with a black and green uniform with gloves and white gloves! There was also a blond haired guy about the same age as the boy. The blond haired guy wore white as he has eyes that turned red and he looked rather ruthless. Eren was shocked as well as Kaneki, they couldn't believe it. Shinichi glanced down at the two,  "Who are you?" He asked. Eren sprung to his feet, "Wha--Wha--What is this?" He stammered. Kaneki also stand a little cautiously as he was injured by the fact on the battlefield! Yuu was surprised, "Who are these guys? How did they get here?" He asked. However, there was trouble as giants, humans who turned out to be body snatching enemies, abominations, and human eating monsters. The others had no choice but to team up with one another in this fight. Eren, Ken, Shinichi, Yuu, and Mika were fighting against Titans, the Four Horsemen of John, ghouls, and other Parasytes. But things were going downhill for them. Eren try to fight but he was weak from his battle against Kaneki as his nose was bleeding. Yuu and Mika were injured slightly but it left them shaken. Only Ken and Shinichi is fending against the enemies in front of them! It was then someone came into the picture, He shot the monsters down with his blood like a gun weapon, he stood there as the others is stunned by this guy, they had no idea where the heck he came from! Blood swarmed in his hand as he was ready for another blow to the opponents. "How did you do that?" Eren said. The boy turned around, he looked to be about 14 years old and he was a bit pale around the edges but he wasn't going to back down now! He had a fight to win. "I'll explain later...Right now, I like to say that I'm Ganta Igarashi....And I...I am a Deadman!" And so; Eren, Ken, Shinichi, Ganta, Yuu, and Mika fought together with one thing in common: All of them are faced with monsters, all of them didn't do anything wrong to deserve such something horrible, and also they have a purpose to live in life. But by their new freakish powers that are a curse of amazing gift that can be sometimes be a terror no one would ever forget! Eren--Titan. Kaneki--Ghoul. Shinichi--Parasyte. Ganta--Deadman. Yuu--Human or better yet, Seraph. And last but not least is Mika--Vampire.

Eren, Ken, Shinichi, Ganta, Yuu, and Mika were sitting around as Migi was there. "I see..." He said, he looked at Eren. "Your hometown was attacked by a giant called a Titan. You lost your mother who was eaten by one of them. And now you are a Titan yourself since your father gave you the serum." Migi glanced over at Kaneki and said, "And you were once human while on a date with a girl who turned out to be a creature known as a Ghoul. But you didn't want to be one. However, despite that, you were kidnapped and tortured so much that it left you with different proportions and made you into what you currently are." Migi then let his eyes looked at Ganta, "You apparently were framed for murder on your classmates and became someone known as a 'Dead Man'." He then glance over at Yuu, "As well as yourself...Your mother had committed suicide, your father wanted to kill you because he thought you were a demon. You ended up in an orphanage, and there was an outbreak that killed humanity...Almost. As a result, you watched your family of other children were killed by a family." Last but not least, Migi glances over at Mika as he then says, "And you, you became a vampire but you have a hatred equally to humans and vampires alike. I see, I believe it is something each and every one of you have in common. You should know..." He gestured to Shinichi, "...he himself went through a tragedy. His mother was killed, one of my kind took over her body and killed him. But luckily, I saved Shinichi and that is why he is somehow different after I merged with him." explained Migi. Shinichi glanced over at his partner, "Migi, you know I'm here. I could've told them that." He said. "I'm aware of that but if you told them, I was concern you would break down and clutched at your chest." Migi pointed out. Shinichi sighed, "So you see. I guess we can find a middle ground." He said. "I don't know." Ganta said, "I mean....It's not like I want a pity party." Kaneki looked down, "Neither of us. But it could work." He replied. "But what makes you think we'll work with you?" Eren said. "Because all of you know is that we're here and we don't know why so we need to find out why," Shinichi pointed out. It seemed that they had no choice but to do so however he would like to know that had to find people just like them.
