Name: Tomoe Akihiko
Age: 17
Appearance: Just another ordinary young man.
Personality: Incredibly tenacious, almost unnaturally so, but far too idealistic for his own good. He's the kind of person that can set a goal and painstakingly figure out how to accomplish it using whatever means are available, and to this end he's developed a rather keen intuition and a level-head. Akihiko is definitely an adaptable sort, he has his priorities straight and usually won't freeze up at every little new development. However, his idealism also makes him the kind of person that would deny himself completion of the aforementioned goal, all so he could save someone caught in the crossfire. Unsurprisingly, his idealism, not to mention his own inexperience in general, makes him very naive. It could be said that his immense dedication is less towards the Fu Sonzai no Genso itself, and more towards what they're attempting to accomplish

Socially, Akihiko's standard upbringing hasn't instilled any peculiar traits within him, apart from his naivete if you consider that one. His demeanor definitely leans more towards the reticent side. Though blatant displays of emotion are hardly uncommon for him, he mostly uses more subtle expressions like small smiles or exasperated sighs. He could easily be seen as 'soft' by some of the more jaded members of the group due to his natural inclination to kind-heartedness, as well as his unwavering loyalty and obvious concern for his allies' safety. Mostly due to his perceived inability to measure up to most of the others in terms of abilities, he believes himself to be a burden and eagerly tries to prove his worth.
Abilities:

• Hacking (and Other General Electronic Know-How) - Akihiko's greatest skill, one honed for the intention of becoming a programmer in the future, but is now used to help investigate supernatural crimes (and general housekeeping purposes). Unfortunately many of its uses are made obsolete by the presence of magic within the agency. Still, if you ever need anyone for something requiring a more tech-savvy touch, you know the guy to call.
• Parkour - Due to the presence of vehicles and other forms of quick transportation it's a skill Akihiko's developed more for showing off and keeping fit than any practical movement. Though there's still occasions where it sees use, such as reaching convenient vantage points or shadowing targets. Practicing this skill has also improved his overall speed and agility.
• Affinity: "Synthesis" - An affinity based around the concept of combining in order to produce something new. Conceptually related to spells regarding 'Integration', 'Analysis', and 'Transmutation'. Within this affinity's main area of influence are spells such as rune arrays, most theurgical rituals, and alchemical processes. In the hands of someone with a lot of magical experience, potential, and time, it could be considered a formidable affinity in its sheer versatility. Unfortunately (Fortunately?) it's possessed by Akihiko, a first generation mage who's definitely lacking in exceptional magical capacity - not least due to the fact he's constantly sustaining a familiar - and poorly trained, with his the closest thing to training being replication of an onmyoji's notes. The extent of his primary magical knowledge extends to the use of runes, ofuda, and shikigami, as well as magic regarding the maintenance of a familiar.
• Eika - His familiar.

Weapons/Equipment:

• Smartphone: Modified for use in hacking. Not to the level of someone like Aiden Pearce, however. More along the lines of simple on/off commands, piggybacking off of security cameras, and accessing/uploading relatively unsecured data.
• Multitool: Equipped with the standard arrangement of tools: scissors, saw blade, knife blade, screwdriver, bottle opener, reamer, pliers, etc.
• Pocketknife: Used to gather blood when using a pen is inconvenient. Rarely used as a weapon due to impracticality. The blade is less than 6cm as per Japanese law.
• Pens: Three different varieties of them. One ballpoint, one rollerball, and one gel. Each of them use a blood-ink mix to get that extra OOMPH out of written spells.
• Index Cards: Carried around in a leather deck holder on his belt.
• Blank Ofuda: Carried around in his inner jacket pockets, as well as up his sleeves and in a pouch on his belt.
• Belt: Contains everything on the list except the phone in one the three three pouches Akihiko's attached to it.

Brief Backstory: A young first generation mage who could have, and should have, ended up living out a normal lifestyle without learning any knowledge of the supernatural world whatsoever. Akihiko is an only child born in Tokyo. At the age of 13, Akihiko moved to a nondescript town not far from Kawa City. It was there that he gained an interest in the paranormal after taking a dare to hang out with the 'weird' kids who were interested in urban legends, ghost stories, and other such subjects. It turned out that they were pretty decent people, and soon enough they became a rather tightknit group of six.

Knowledge of his capabilities as a mage came about as more or less an accident. He had been surfing the Internet bored and alone, when he decided to try his hand at a simple ritual. After doing the appropriate research on something that seemed to be easy to cast, he attempted the ritual and to his surprise (and horror) found that it actually worked. He never told anybody, and just kept it his little secret as he continued with life as usual.

In the summer prior to Akihiko's first year of high school, the town saw the occurrence of a string of disappearances with no obvious rhyme or reason. One of the member of their group, a boy named Takeshi who was the son of their local temple's priest, was particularly adamant on investigating. With nothing much better to do with their summer, they all began playing detective. They had actually managed to make a bit of progress. Then slowly but surely, Akihiko's friends began getting picked off. The rest began dropping the investigation entirely, though that didn't save them one bit. It was at this point in time that he began delving back into the magical world, looking for something to help him survive. He ended up teaching himself how to use Elder Furthark runes after a lot of trial, error, and damage to his backyard. Unfortunately it didn't save him from getting targeted nor did it save his parents from getting murdered by a rogue mage's familiar, but he'd managed to buy enough time for himself to get saved by Eika.

After escaping from death, Akihiko headed to the temple to warn his remaining friend. However, in another stroke of bad luck, he was too late. With nowhere to go and nothing else to do, he took it upon himself to continue the investigation once more, for the sake of his fallen friends and family. Working off of Takeshi's notes, and the knowledge he'd gathered using his own skills, Akihiko eventually cracked the case and went to take down the individual in question or die trying. He never got to do it, as it seemed that someone else was after the mage: an organization by the name of Fu Sonzai no Genso.

Immediately afterwards Akihiko approached the one that looked to be the leader and the rest, as they say, is history.

Name: Eika
Age: Created 18 years ago.
Appearance: Two sides -> of one coin.
Personality:
In order to contrast her rage, Eika's personality is actually a calm one. She is able to maintain her head in most situations -- until it comes to a point of her "Master", as she refers to Tomoe Akihiko, being harmed. Once his safety comes into play, she loses all pretense of her own well-being and her own desire to retain a calm persona and shifts into an increasingly angered persona until she shifts. When regarding new people, she's usually taking her time to gauge whether or not they'll hurt him, or seeing how he responds to him. If he doesn't like them, she's quick to get in the way. If he does? She can be courteous.

She does actually have two issues, regarding her state.
The first is a phobia known as "Athazagoraphobia". It is a fear of being left behind or abandoned, created from being kept in a cage for so long. Thus, she can be come easily angered or upset if Akihiko opts to forget she's around for him.
The second issue is her Berserker side. She's afraid of letting herself get to that point around other people because she does not want to hurt his friends. Thus, should she be forced to shift, she'll feel all too remorseful or disheartened when she returns to normal and communication won't be the best in terms of capacity.
Abilities:
Affinity: Perserverance- Perserverance is Eika's own, granting her Master a lowered maintenance cost to keep her going and allowing her to use any mana that is normally flowing through her body to heal her at an extended rate in order to enhance or alter her body's natural processes. Rather than needing rituals or runes, she simply converts this mana inside of her body to speed up or enhance natural processes. It's a self-helping Affinity as such.
Strength - As she was created originally to be a guardian of sorts, Eika's strength is far beyond the capacity of any human being's -- able to punch down concrete walls, stop trucks with her foot, etc.
Rage | I'M A MONSTER - Eika is classified as a "Berserker" or a "Rage" Familiar. The angrier she becomes, the harder she hits. If she reaches a point where she can no longer control her emotions or is overloaded by mana, her body shifts into its "Berserker" form, as seen in the second image above regarding her Appearance. She's twice as strong, twice as fast, and twice as durable -- at the cost of losing the ability to identify anyone other than Tomoe as friend or foe. Alone, she doesn't know when to stop, which can lead to excessive damage to her body until she's completely incapacitated and requires extended periods of rest or healing. Another method of enraging herself would involve wiping her own blood into her eyes to give her "Red Vision", essentially angering her in a similar manner that a bull is believed to be angered.
Parkour - Because she didn't want to lose her damn Master when he went running on top of buildings, she picked it up. Smashing through a wall like the Kool Aid Man doesn't help with everything, it turns out. She was a little disappointed to learn.
Weapons/Equipment:
Her Body - She a tank and a fighter. She's the one that goes on the frontline to keep Tomoe safe, reflex and pure force of will used to shrug off any pain that comes of it. In return for her lack of range-based abilities, she hits harder than a sixteen-wheeler. Her punches and kicks can hold enough force in them (or channeled mana) that she can actually hit hard enough to force air to become an added hit behind her attacks (essentially, making it so she could punch one person and have the force of it travel through two people behind that person).
"Pancangan" - The name of her oddly-shaped blade forged upon going Berserk. It's capable of slicing through metal in clean swings due to her strength, and she is able to use it single-handedly, despite its weight. Unless someone had her natural strength, they'd have to use both of their hands and still probably struggle to even lift it.
Demon Sense - The ability to sense when demons are around as if they were on a radar and pinging to her. She can track them down this way.
iPod - Bought for her by Tomoe. It's loaded with a bunch of songs (most classical, J-rock, or rap) as it's been shown that listening to it can calm her down. She's actually very protective of it, since it was a gift from him. Kept in a survivor series case to keep it from breaking during combat.
Brief Backstory:
Eika was created as a Familiar for a cult leader, originally. She was to be a symbol of strength and a sign of his ability to lead and guide his people. Unfortunately...It didn't go quite as planned. This man that created her did not understand the nature of his Familiar, and he kept her locked up like some sort of animal. The consistent drain of her Affinity trying to keep her calm made him sickly as a result, and it eventually came to a point where the cage she was kept in couldn't protect him and his people from the Monster within her. The overflow emotions that came running in as she watched his cult followers cursing her and treating her like a circus show day by day made her snap, breaking free as the other side took over and tore her cage in half. Within ten minutes, a cult of seventy people had been slaughtered with her own Master bleeding out in his bed.

Not quite thought out, on her end. But then again, she hadn't been thinking when she'd opted to start a murdering spree.

She fled the scene, realizing what had been done, and running to the nearest town she could find -- Kawa City. It was small...Small enough to try and resurge the belief she needed in her to keep herself from fading out of existence. So, as much as she didn't want to do it, she had to terrorize the town. No killings, no acts of bombs or anything of the like. ...Just...displays of her strength. Signs that something like her existed. It took a while, and the longer it took, the more of a drain it had on her body. It hurt to move, hurt to try, but...she forced her way through it, body feeding off of the small traces of mana that she'd manage to come across here and there. It was a painful life, that was a defnite.

Enter Tomoe Akihiko.

She'd noticed him. A mana source. A person like the man that had created her -- someone that could keep her alive. So she followed him out of curiosity -- and lucky him! -- she managed to come just in time to see a demon of sorts attacking his home. Parents not quite lucky enough to survive, she jumped in as it was about to kill the poor boy and offered him a deal while she held back the killer.

She'd save his life if he'd promise to save hers.

And he agreed. The willing donation of his mana surged through her body like an adrenaline injection, ceasing the pains she'd had for the past years of lurking through this town and allowing her to punch her way straight through the demon, dropping it to the ground and taking it out in a prompt manner.

That's when she began to explain to him what she was -- a Familiar. By accepting her offer, he promised to take her on as his own, keeping her alive and going in return for her protecting him no matter where it was he went. And with her own brand placed on his body, the deal was sealed, rendering her with a brand new life that didn't involve her trapped in a cage as a result. Thus, when he went to go to the organization known as Fu Sonzai no Genso, she followed right behind him.
