Employee Roster:
Ando Toshiko, Head of Fu Sonzai no Genso
Akemi
Hashimoto Ryo
Zeke Pascal

Name: Ando Toshiko
Age: 28
Appearance: She's a bit of a blatant expy. ^^;
Personality: Toshiko enjoys spending life with people she cares about, and generally makes for fairly pleasant company. However, she will change her behavior depending on the situation. When talking to employees, she is friendly, calm, and kind. When speaking with a perpetrator, for example, she makes a drastic change, approaching cruelty. In addition, it is not difficult to rouse her to anger and she has a remarkable lack of patience for someone who has taken a profession as a detective. When sufficiently angered, she will remove her glasses and and begin taking things extremely seriously. She enjoys cigarettes and seems to have something against organizing her office. Toshiko's ultimate goal is to attain immortality, as well as ensure no-one causes too many problems that interfere with having a pleasant life. Toshiko is terrible with money and spends incredibly frequently, sometimes on magical items and other times on things she simply thinks are interesting.
Abilities: Toshiko has Fire as her Affinity. As such, she is highly skilled in spells relating to fire. She is capable of casting spells by "carving" symbols in the air using a lit cigarette. Notable among her spells is an Instant Ignition spell. While it requires a full magic circle to be "carved" in the air, it will instantly ignite a target. As Toshiko's affinity is fire, she is also skilled with spells involving "consumption", "ignition", and "destruction". In addition, she has learned spells outside of her affinity. These spells are primarily wards and illusions, which she uses to conceal the Fu Sonzai no Gensō building from the eyes of regular humans.
Weapons/Equipment: Toshiko has a great deal of cigarettes with her at almost all times. Not only does she like them, but they aid her casting. She also has a suitcase, though she doesn't actually use it to store any important items... She says it houses something interesting and leaves it at that.
Brief Backstory: Toshiko was born into the Ando family, a family of magi with the goal of accessing the plane of existence the gods dwell on. Early in life, Toshiko was mentored in magic by her grandfather. When she reached her late teens, she was sent to a Mage Circle in London to train. It was here that she chose to abandon her family's goal, firmly believing it to be unattainable. While her family was initially outraged by her decision, they eventually relaxed and came to accept their daughter. This was, in part, because Toshiko's sister had not displayed the same desire to give up. Deciding to pursue the goal of immortality, Toshiko returned to Japan and founded the Fu Sonzai no Gensō detective agency in an effort to ensure pleasant life wasn't disrupted. Also to make money.

Name: (Ando) Akemi

Age: Actually six, physically and mentally fifteen.

Appearance: Younger than she looks in both meanings of the word.

Personality: Almost completely void of emotion in normal situations, you'd have to wonder if Toshiko made a mistake in creating her. As it turns out, Akemi simply doesn't show it very well. She's actually somewhat shy, even if you'd never notice her discomfort, and loves cooking. She's definitely got her childish points, and treats Toshiko like her mother (which is more or less accurate).
For some reason, the homunculus finds cars terrifying.

Abilities: Created for the purpose of protecting Toshiko, Akemi's notable skills are simply straight-up combat, with an emphasis on making sure the attacker can't cause problems again making her find it rather more difficult to simply subdue someone. Despite being equally good with her sword or unarmed, she prefers to cut things even though this adds in the difficulty of hiding a weapon when travelling around. As a homunculus made to fight, her physical abilities are beyond what a human could ever get by training... as is her appetite.
Aside from combat skill, Akemi is a good cook and efficient cleaner, which is a good thing for the agency itself, otherwise the food quality would probably decrease to 'what can be cooked solely by boiling water' and grime would build on everything. That's what Akemi expects, at least.

Weapons/Equipment: Her sword's magically reinforced, because you never know when something soft and fleshy is going to turn out to be as hard as steel when the supernatural is involved.

Brief Backstory: Created several years back as a safety net, when it wasn't certain that the Ando family would simply accept their daughter ignoring all their plans, Akemi's original purpose as a bodyguard against retribution turned out to not be needed. Still, with nowhere else to go--and at the time looking like a child--she stayed with Toshiko, getting interested in cooking and happily taking better care of the adult mage despite their relative life experience. Even after coming back to Japan and starting a detective agency, she's kept it up.
The maid outfit was her idea.

Name: Ryo Hashimoto
Age: 23
Appearance:

Personality: Ryo is an optimist through and through. No matter how bad things get he will always try to find a bright side and keep his spirits up. He is a happy guy most of the time, but should he get truly angry everyone should beware. Ryo doesn't like to get angry, because he knows he gets very violent when he does.

Abilities: Ryo is a Mage with an affinity for Darkness. He can control shadows, take light away from areas and other similar things. He has also learned to travel through shadows which would be outside his affinity, but limiting the travel to shadows only simplifies things.

Weapons/Equipment: Just his phone, his wits, and his fists.

Brief Backstory: Ryo grew up having a fairly ordinary life. He and his family were Magi but because of the secrecy of the magical community Ryo felt as though he was never living up to his full potential. Ryo grew up learning magic and about famous mages from the past, but he could never use any of it outside of his house, he felt like he was meant to use his magic for something more. For most of his life Ryo has taken some form of martial arts, he's never needed to use it but he would be pretty good in a fight if the need arose. After high school he went to school to become a teacher, thinking that's what he could do to help the world. Shortly after finishing his schooling he learned about the Fu Sonzai no Gensō detective agency, and he knew he wanted to join. To finally do something with his magic to help others.

Name: Zeke Pascal
Age: 112 (Appears 25 at most)

Appearance:

Personality: Zeke is a romancer, he loves to love. In his 112 years he has loved and lost so many times, but he can't stop himself. Some would call it lack of self control, Zeke sees it as him over-committing to relationships. Zeke enjoys food and cooking more than that, it doesn't sustain him in the slightest when compared to blood, but he enjoys the taste more than anything and has discovered that a particularly rare steak can be useful as a light snack.
He loves his bike, being one of the few things that has lasted the decades Zeke has been alive.
For the past ten years Zeke has been going through a mid-life crisis and is re-living the 50's, taking out his old Greaser clothes and rediscovering his love of cigarettes.
Zeke occasionally gets into a depression if he reminisces about his past, his loves more specifically.

Abilities: Zeke has the traditional powers of a Vampire, superior strength and speed, regeneration and immortality. Biologically Zeke's senses have been enhanced and has become immune to minor illusions and after years of practice has mastered persuasion.
Immortality has the side effect of giving Zeke an insane amount of time of which to pursue whatever skill that takes his fancy. In the past he has been a mechanic, a carpenter, a bartender, a boxer, a stage actor and at one time he worked as a journalist.

Weapons/Equipment: A 1941 Crocker Motorcycle, heavily tinted sunglasses for the rare times he has to go outside in the day, a hip-flask of chilled blood, a pack of cigarettes, a battered notebook of loves lost, a comb and a silver knife.

Brief Backstory: Zeke was born to a bog standard family, no great tragedy and no real troubles, beyond growing up through the great depression and prohibition periods. When he was 24 Zeke worked as a mechanic, he wasn't bad at it, but he did have a bad habit of having a messy workplace. One day, as all stories do, Zeke was working under a particularly rich man's car when the the jack keeping the car up suddenly broke, and he was crushed underneath the steel chassis. Before Zeke lost consciousness he heard a muffled voice say
"Why'd you mess up my car?" Next thing he knew he woke up on a morgue table with a rather regal man with a snow white moustache standing over him.

"Well now that you're up, you can fix my car Zeke!" Zeke must have looked extremely confused so the man jumped into an explanation "Zeke you died under my car and made a real mess of it. I did this so you so that you would repair it. I am a Vampire. I resurrected you as Vampire, so now you will have... issues in sunlight. I'll give you a handbook later. Now fix my car" lifting Zeke up by his collar the man dragged him to a police impound lot and forced Zeke to repair it. Once Zeke was done the man thanked him and drove off into the midnight, leaving Zeke to figure out what was going on without the help of that promised notebook.

Years later Zeke managed to keep his 'eternal' life running for over 100 years despite other magical forces trying to shorten it, the 90's was particularly rough since Buffy the Vampire slayer made his life more difficult than he anticipated. Now the 21st century Zeke was tired and longed for simpler days and led him falling into a mid-life crisis of sorts, he wanted to do something worthwhile, to actually help people that won't kill him for his trouble, especially after a decade or two of achieving little besides staying alive Zeke stumbled across the Fu Sonzai no Gensō.

Name: Iwajima Jun

Age: nine years old.

Appearance: ] definitely the appearance of a reliable supernatural detective!

Personality: Jun can at times be incredibly focused, serious, and mature, which is only natural for someone who has worked hard enough to nearly master certain areas of Onmyoudo at such a young age. On the other hand the fact remains that he's still a child despite his high level of skill and his tendency towards hyperactivity is made worse by an overactive imagination fed by a combination of living in a magical world and ready access to media.

Abilities: Possess a high degree of skill with Onmyoudo, his affinity being the number 9. This allows him to use a variety of spells and techniques with his ofuda so long as they ultimately have something to do with the number nine either conceptually or concretely. He also has a surprising amount of martial arts expertise for someone his age, due to being raised to fight yokai.

Weapons/Equipment: Has his trusty detective's trenchcoat, though the only thing unique about it is that its pockets have ofuda on them that allow them nine times as much storage space. mainly used for carrying ofuda.

Brief Backstory:
Jun was a son of a powerful family of onmyouji who primarily made their living combating rogue yokai and other supernatural creatures. Toshiko knew his family from the time when she was in training and owed them a few favours for reasons she'd rather not mention. Because of his family's work, Jun was strictly trained in onmyoudo and related lore before he even started primary school, even to the extent of being given the Gazu Hyakki Yagyo in place of ordinary picture books. However his entire family died under mysterious circumstances. Under previous instructions his father had given him just in case anything ever happened that left him on his own, Jun sought out the Fu Sonzai no Gensō Detective Agency and has been living and occasionally working there part-time ever since, hoping to become a real detective some day and solve his family's case.
