Name: Kiyohara Homura
Name, supplemental: As an heirloom, Homura’s sword is properly called something like Vermilion Harvest Moon, but its tsukumogami spirit usually just goes by "Mizuki."

Personality:
Homura
Homura, despite her name, is a cool and collected individual. She tends to remain calm in most situations and isn’t the sort to back down from a threatening opponent. She is polite, kind, and dutiful, and takes her training and her job as an agent seriously. Her somewhat detached approach to life can easily lead to her being “spacey”, and it’s not altogether inaccurate. She’d miss quite a lot if she didn’t have a second set of eyes watching out for her.

Homura’s life isn’t all training in kendo to inherit the family’s style and continue the family business as some sort of spirit hunter. She enjoys anime and video games in her spare time, and plays some sort of otome game on her smartphone almost religiously.
When particularly nervous or flustered, she has a habit of messing with her glasses, usually cleaning them.

Mizuki
Mizuki tends to behave in a parental manner toward Homura, and keeps her own past and anything she might know close to her chest. She’s often the one required to be the voice of reason and warn Homura of possible danger, and is not at all above laying on the sass when she does. One of her main interests is understanding humanity through fighting.

History:
Homura is an ordinary girl. Her family just has an extraordinary job. Sometime around 1972 when the Akasha scourge first turned up, a nice family sword awoke from, as she put it, “a nice nap” and convinced the current head of the household that they needed to go out and fight monsters. They quickly joined the newly formed Akasha Agency, and “Agency Operative” has pretty much been the family job ever since.

As the current heir to the family style, it’s now Homura’s turn to sign on with the Agency and take on the “family business,” while her father moves on to more of a role advising and training other agents. Homura grew up with her training and the Agency in mind, though this didn’t stop her from having a more or less normal childhood. With youkai and their ilk being something of an open secret in Sentouji city, it wasn’t even like she had to keep everything a complete secret.

Homura is a relatively new member of the Akasha Agency, and among their younger ones outside of the Specialist training program. She has yet to prove herself in any major capacity, although she’s no stranger around the local Shokuden. She’s been on a few missions, but is still terribly green. At least she’s got a good advisor in the form of her own sword.

Fighter, Rank 3
Talents
Sword: Katana - Homura's pretty good with a sword. It's how she fights things.

Unarmed Martial Arts - A secondary focus for Homura’s style. She knows her way around punching and kicking, at least.

Quicksilver Moonlight Style - A martial arts style passed down in her family, and originally learned through the tutelage of youkai. The style relies upon a bridging of the mortal and spiritual worlds, and emphasizes powerful, decisive strikes.

Third Eye Opened - Through focus and spiritual training, one can become aware of the spirit world, and becomes capable of sensing dematerialized or invisible spirits and similar otherworldly beings.

Graceful Crane Stance - A technique that grants perfect balance and lightens the body by focusing ki. It allows the user to remain sure-footed in any situation, and stand on surfaces that would otherwise not support her. For example, she could effortlessly balance on the tiniest ledges or the top of a pine tree, and could run across deep snow without sinking into it.

Collaborative Possession - Homura allows Mizuki to possess her body. While they are two spirits in one body, typically Homura is still the one in actual control, although Mizuki can take control if she needs or wants to, though it’s usually only with consent. While in this state, Homura is essentially half-youkai, and gains enhanced strength, speed, and durability.

Some of Homura’s hair turns white while she’s in this state, and if she stays in it for a long time, some of the whitening is permanent, leading to white streaks in her hair. She also tends to suffer when she comes down from possession, leaving her tired, lethargic, and disoriented.

Techniques
Spirit-Cutting Strike [Gekkou] - A strike empowered by the youkai blade, Gekkou strikes at the immaterial. An otherwise ordinary strike that can cut dematerialized spirits. In the case of a possessed target, only the possessing spirit is struck, while leaving the body unharmed.

Slayer’s Art: Form 1 [Mangetsu] - A simple strike that focuses the full power of sword and wielder into a single, decisive attack. A powerful, but thoroughly unsubtle attack designed to end a battle as soon as it has begun, or rend through colossal opponents.

Phantom Heartbreaker - A combination attack between Homura and Mizuki. Homura throws Mizuki past her opponent. Mizuki then returns with a diagonal slash, followed by a quick stab that flows into a series of quick strikes from the left and right. Homura continues her assault unarmed, carefully timed to avoid any blows from Mizuki that their target might avoid.

Homura cannot use this technique and her possession talent at the same time.

Relationships:
None yet

Other:
Mizuki is a member of the Akasha Agency in her own right, and has been for decades. She has an effective rank within the agency of around 5, in terms of seniority. Typically, her role is more of an advisor or mentor to Homura and other younger agents.

She has a voice and can speak audibly, although if she’s possessing someone, she’ll typically speak through them. Whether possessing someone or not, she can speak mentally to anyone in physical contact with the sword. Her manner of speaking tends toward the archaic.

Name
Karine Yuryevich (most people just call her Karin)

Age
18

Appearance

Here's a link since the drawing is pretty big.

Karine has short, brown hair that is usually messy, and her eyes are a deep blue. Though her warm clothes worn all year often hide it, she has an athletic build that reflects her active lifestyle.

Karine usually wears warm clothes at all times, the lightest clothing she commonly wears being a tracksuit. When utilizing her abilities, ice crystals form all around her, frosting her skin, clothing, and lingering around her in a way that looks like her hair is lengthened.

Personality
Karine tempers a burning heart with her cool (pardon the pun) exterior. She loves physical activity and hates standing still. She'll likely try any activity she can just to keep things moving. This has lead to her having a somewhat short attention span: She often does whatever she thinks is fun at the time, and often will be doing something different the next day. This has let her have a shallow knowledge of plenty of things, but she never really focuses long enough to master something.

She enjoys healthy competition regardless of winning or losing, but despises foul play. She generally dislikes dishonesty; she will often bluntly call out things she considers to be false or lies.

With friends she is energetic and somewhat exhausting (if left unchecked). At times she has to be reminded that not everyone shares her innate desire to keep moving. It's in her nature to go for physical contact with people she knows; she is said to be an aggressive hugger.

She becomes lazy (or rather, overly content) when given a supply of heat. Oftentimes the only way to get her to do anything is to remove the source. On the counter side, if she is forced to sit still for too long, or in a generally cold area, she tends to get abrasive. Some friends may note that she acts differently as the seasons change, though her wardrobe of extremely warm clothes helps keep her from being eternal cranky during the cold months.

History
Karine is the daughter of a man and yuki-onna. Her father is from Russia, but Karine was more or less raised in Sentouji. She grew up fairly separated from others, though whether that was due to a solitary spirit or her status as a half-youkai is up to debate. Despite being a quiet child in elementary school, she came out of her shell more in high school, most notably when she went through a trial run of almost every single sports club in her school.

Class Name
Ice Hand (Fighter-Arts) Rank 2

Trained School: Snowfall
Karine has a natural affinity with cold and ice manipulation. This school is a focused variant of Sonshou. Actually, it basically is just Sonshou, but Karine's mother insisted that it be given its own name to respect Karine's heritage.

Talents:
-Woman-At-Arms: Karine has not opted for studying any particular style of combat, but instead has learned to fight with her ability to shape ice into weaponry. She can adapt her style and weapons to match the circumstances of a fight, but she is not as strong with any individual weapon as someone who has trained for a single fighting style.
-Cold Immunity: Karine is nearly unaffected by extreme cold or icy terrain.

Signature Spells:
-Crystal Arms: Karine can form ice into weapons and items. These weapons/items are not particularly strong, but she has excellent control over them and if broken can be re-created quickly.
-Blizzard: Lowers ambient temperature around Karine considerably; within a small amount of time the area around her will begin to freeze and become difficult to navigate by others. If sustained further, the area will become cold enough to be a danger to other living things.
-Heat Sense: When focusing, Karine can use her innate sense for warmth to discern anything that gives off heat within the area, as well as recent paths heat sources have taken.

Fighter Techniques:
-Feint: Karine can use her control over the shape of her weapons to attack in ways that can avoid or break guards. For example, swinging with a light sword and suddenly changing it to a heavy club, twisting the shape of a spear to strike even if deflected, and lengthening a weapon to hit at an unexpected range.

Relationships
~~She does need a warmth source friend if anyone wants to help out with that~~

Genichiro is a man of rather unassuming appearance, both in terms of physical characteristics and presentation. Scrawny, with dark hair and eyes, and a slightly bad posture, there’s nothing about Genichiro that really stands out in a crowd. Even in terms of clothing he’s dull, tending towards plain clothing and muted colours.
"Ug̵̡̒l̷̹̊y.̴̖̈́" "I ̴͚̈t̴̜̎hi̵̳̔n̷̡͋k yo̸̦̐u're p̵̢̿retty..̶̫̇." "Wh̵̳̑ỳ̴̡ cą̷͑ń̶͉'t you j̷͇͆ust̶̹͐ lo̵̦̍o̸̻͑k lik̴̟̕e sö̴͕mḛ̴̈́o̵̯̔ne el̸̺͝s̶̱̏e?̶̬͑"
Genichiro is very curious, the kind of person who desires to understand every new thing he sees, though nowadays he’s a little more cautious about that sort of thing than he used to be.
"Ï̶͔ ș̵̿aid Ị̸̍ wa̸͈͝s̵͍̕ sor̷̪̓r̴̦͋y...̷̡̎"
He could be described as being quite nerdy and certainly, he tends towards shyness when meeting new people, but he tries to be at least a little outgoing and gets over his shyness with new people quickly enough for it to be more of a barrier to entry than an ongoing hindrance when interacting with him. Hooking him with an interesting topic, particularly one rooted in science or philosophy is the most surefire way to break past his barriers.
"F̸̤̌u̸̦̎ckin̵̝̍g̶͙͊ nerd̸̫̆!" "Lǫ̴͆ser̸͚̓!" "Doñ̷̦'̵̧͑t list̷̘͋e̵͖̿n ̴͚̿t̶̜̓o the̶̞̽m̶̘̈́, yó̴̬u̴̜͐ tasṱ̸͠e grȅ̶̹ả̷̻t tḣ̸̗e w̸̖̃ay̸̲̿ you̴̖͊ ̴͇̓arĕ̸͉."
At times Genichiro can come across as a bit of a know it all, between being well studied and his tendency to correct people on minor technical details. He doesn’t really mean any harm by this, more that his own curiosity sees him wanting to know as much as possible himself and he assumes that others would also feel the same way and want to be corrected when they make mistakes.
"You̴̥̿ thin̶̡͠k̵̹̎ you'̶͚̊ṟ̴͠e smar̵̪͊t? Ju̶̝̔s̵͔̀t wȃ̸̫ḯ̷̳t tiḽ̶̕l̴̜̀ yoů̷̮ get̵̬̍ a loà̴̙d̴̫̑ of us̸̛͉!"
Genichiro expresses a strong sense of empathy and desire to do what he can to help others. He wishes to be able to use his aspect as a tool to further that goal and fully believes that he could use its knowledge to solve all manner of problems on a global scale and even improve living standards beyond that. Unfortunately, experience has led him to largely avoid the use of his aspect to any great extent, in service to that goal or otherwise, at least until he can get a better grip on his power.
"Do̸͙̚n̶̰͑'̷͚̋t b̸̬͂e likê̸͎ ̵̫̊thȧ̷͕ṱ̷͛. Bĕ̵͉ ̴̧͐like̷͋ͅ ú̴͜s! We̴͉͐'̴͋͜re gre̶̛̹a̸̟͠t rol̸͈͊e mode̴̘͊l̵̲͆s!"
In addition to his actual personality, tend to lead people into thinking he’s anywhere from weird to downright insane. His reactions to his aspects commentary, tendency to talk to himself, a habit of doing several things at once, and depending on how many questions he’s asked recently, sudden and erratic changes in personality, all tend to arouse suspicion in those around Genichiro, especially considering that without any physical manifestation to his aspect, as is common in most specialists, his behaviors are somewhat harder to dismiss as supernatural bullshit to outside observers.
"I̷̭͠ ̶̗͂AM Á̸̺ FU̵̫͠C̶͚̆KING̴̔ͅ ̴̛̟DḬ̵̚N̸͚͂OSÃ̵͓Ù̵͎R!!̷̧̊ MO̶̹̓O̷̥̍!" "Sh̴̙̃ù̸͕t up̴̘̄ alre̴̳͑a̷̞̽dy.̴̱͆"
