Tsuruki is reading through the documents as he just got back to Gordon and Rui's house.
Tsuruki: "Tanamura Kenichi? If I'm not mistaken, I believe he's one of the candidates for EAS6. Looks like they were putting him through the same tests as me. I think the elements he wields are water, lunar, and blood; so why is he involved in the same tests?"
Tsuruki quickly reads through Tanamura's profile and moves on to the rest of the files. The front of the file reads "Seven Devil Experiment".
Tsuruki: "Seven Devil Experiment... Seven... Seven meaning the seven elements? That's the only connection I can think of, but what about devils? Assuming they exist, what would be their role in this experiment? Are they trying to summon one?"
Tsuruki continues to read through the files; looking for answers to his questions.
Tsuruki: "Wait, wait-wait-wait-wait. So elements are granted by guardians. There are seven guardians, one for each element. So what do devils have to do with this? It says that one of the goals of the experiment is to have an elemental spiritually connect to a guardian in order to gain the ability to wield more elements. This explains how I was able to start wielding the lightning and dark elements, but it only leaves me with more questions about devils. What is th-.... Ah shit!.. My head!..."
Tsuruki falls to the floor with his hands around his head. He feels a sharp, painful squeezing throughout his head. The walls, the bed, the entire room starts spinning around him. The quiet screeching of crickets in the night begin to faint away. Tsuruki starts to lose consciousness.
Tsuruki: "What's... happening? Why is... everything spinning? The- the files... I need... to hide them..."
...It's dark. There's no sound, no smell, nothing to see, nor to touch.
Tsuruki: "What is this? What's going on?"
Suddenly, a quiet voice can be heard. It's too quiet to make out what it's saying. Tsuruki yells out to it, but gets no response... The voice speaks again, but louder and clearer this time. It was a man's voice. He sounded angry. As time went on, the voice became more and more clear. Tsuruki could also start to see light. The light widened and a laboratory room appeared. Tsuruki realised that he was seeing the memories of this man. It was like a first-person movie. He saw everything the man saw, but through some sort of light. He also started to hear some of the researchers. They were saying...
Researcher 1: "The test was a success! Quickly, give him a dose of stabilizers!"
Researcher 2: "On it!"
The man was screaming. Tsuruki couldn't tell whether it was a scream of pain, fear, or anger. Perhaps it was all three. Tsuruki looked at the ID number on the man's wristband, it was the same as Tanamura's. Tsuruki was watching the experiments through Tanamura's experience.
Tsuruki: "Did I.. connect to Tanamura's memories through a spiritual connection?"
???: "You did"
Tsuruki: "Eh?! Who's there?!"
Tsuruki heard another voice. It was a girl's voice, but it sounded different from the other voices. It sounded like it was in the same room as him. He turned and looked all around him, but saw no one.
???: "No matter how much you look around, you won't be able to see me. Anyways, sorry to intrude, but I'm going to have to take over your body. I hope you don't mind"
Tsuruki: "Wha-..of course I would mind. Who are you? Why are you taking over my body"
The unknown girl goes to possess Tsuruki, and heads towards his soul.
Unknown girl: "Hee hee, I wonder what his soul looks lik-"
The unknown girl only touched his soul for a brief second, and only a brief second was needed for her to see what she was intruding on. She saw a dark, ferocious aura that wrapped around Tsuruki's soul. She felt a heavy, powerful force pushing against her.
Unknown girl: "Ho- Holy crap, that is one crazy aura. I don't know if I could handle this one. Who exactly is this boy?"
The unknown girl left Tsuruki's body, and went on to ask who he is.
Unknown girl: "Hey, what's your name?"
Tsuruki saw the unknown girl leave his body. She had long silver hair with a lone strand of it covering the center of her face. She had cyan blue eyes and a slender body; about the height of Kira. She floated around and had a white glow to her, sort of like a ghost.
Tsuruki: "Uh, its Tsuruki. Hey weren't you just possessing me or something?"
Unknown girl: "Th- That's... I decided to spare you. Your soul was actually suuuuper weak, so I decided I would go and find a stronger one"
Tsuruki: "Ehhh?! My soul is weak?"
Unknown girl: "Y- Yep, I looked in, and almost gained control just by looking at it"
Tsuruki thought to himself... "She knows that I know she's lying, right? Well, I wonder if I can get some answers from her before she leaves".
Tsuruki: "Haha, well that sucks, anyway who are you? And what was that spiritual connection all about?"
Unknown girl: "I suppose I can tell you my name. I am a spirit given the name Emu. Also I believe you had a spiritual connection because you met certain requirements for it to happen. For example, you could have looked at a picture, saw a name, read something or someone's history, or even touch them and you would fulfill requirements. Once you have met all the requirements for a specific person, you have a spiritual connection. Also requirements are different depending on the person, and their relationship with you.
Tsuruki: "I see, it must have been the file information, and the fact that we were part of the same experiment that led to a connection. So how are you here then?"
Emu: "Spirits are part of a spiritual world. It's an identical world to the physical world. When we see a connection taking place, we're able to sort of pop right in. Being in a spiritual connection makes your spirit vulnerable, which is why a spirit takes over spiritual connections"
Tsuruki: "Then how do I avoid having a spiritual connection?"
Emu: "Hmmm, I don't think you can. The problem is you're not aware of what the requirements are, so you can't really avoid it. Although it is quite uncommon to have one"
Tsuruki: "Hm, alright, is it possible to avoid having a spirit possess me?"
Emu: "Becoming stronger. By becoming stronger, you strengthen your soul. Therefore, it becomes more difficult for a spirit like me to take over"
Tsuruki: "So you admit to me having a strong soul then?"
Emu: "Wha- well... that's not what I... Okay fine, yes your soul has a powerful aura and it wouldn't have been possible for me to take over. Actually, you probably won't have to worry about any spirits taking over"
Tsuruki: "Oh, well that's good to know. What about my body in the physical world, what happens to it?"
Emu: "You disappear. Your physical body moves into the spiritual world. The spiritual world separates your spiritual self from your physical body. So right now your body is just floating through the spiritual world somewhere"
Tsuruki: "Eh?"
Emu: "Don't worry though. Once it's over, you return to the physical world perfectly fine. Well, as long as you don't get possessed. If one gets possessed, the spirit will have full control over the soul and body. You won't be conscience until it leaves. Assuming it leaves your body without your body being lethally damaged.
Tsuruki: "Well then, I should definitely avoid being possessed. I'll have to grow stronger. Also what was your goal if you possessed me?"
Emu: "Oh, uh... I wanted to see my Mother. I died, and the blood guardian brought my soul here. The guardian gave me knowledge of the spiritual world, elements, elementals, and guardians. The guardian also told me a way of how I can see my Mother, so that's why I tried to possess you"
Tsuruki: "I see, I'm sorry to hear that"
Emu thought to herself... "He's polite, and thoughtful even though I tried to possess him. What a strange boy".
Tsuruki: "Tanamura's memories are starting to fade, so I don't have much time. If it's possible, can you share with me everything you know, and in exchange, I'll help you see your Mom again?"
Emu: "You- You'll help me see my Mother?!"
Tsuruki: "Only if you share your knowledge"
Emu: "Yes, I'll tell you everything I know. Do you have some sort of plan?"
Tsuruki: "In order for a body to come to the physical world, it needs a soul right?"
Emu: "Yes, that's right"
Tsuruki: "Okay, so here's my plan. You go find my body and enter it, then when I start heading back to the physical world, my soul will enter back into my body. I belive it'll only work as long as you enter through my brain, otherwise our souls will collide and something bad will probably happen. Sound good?"
Emu: "I'm not sure. There's no guarantee that my soul won't be pushed out of your body when you go to enter back into the physical world, or even worse, my soul blocks yours from entering. In that case you'd be stuck here"
Tsuruki: "Emu. Believe in me, I promise it will work"
Emu: "Alright then, I'll believe you. Don't come crying to me if you get stuck here"
Emu heads off to Tsuruki's body. Meanwhile, Tsuruki looks back to Tanamura's memories. While Emu was explaining things, he kept an eye on them. Nothing major happened, but Tsuruki did notice that Tanamura's appearance was changing. He noticed little horns forming above his forehead, and demonic eyes, just like his own.
