Kihara Chinatsu

*Captain Emo*

Kihara Yuiichiro *(Biological Father)*

The EYE Operative *(Former)*

**Kihara Chinatsu** *(木原千夏 Kihara Chinatsu)* is the adoptive older sister of Kihara Eiichiro, the biological daughter of Kihara Nana and Kihara Yuiichiro, and the brain and engineer of the mercenary group IDEAL. Unlike the other members of IDEAL she wasn't hired, rather she was forced into joining by her father Kihara Yuiichiro as he believes that Chinatsu has enough knowledge in the art of science to be able to aid IDEAL as it's engineer.

Along with the rest of IDEAL, she became a part of CERBERUS after the death of the original members of The EYE and their subsequent ownership transfer of the organization.

## Personality

Chinatsu is a researcher through and through, she rejects the existence of the supernatural created by magic despite knowing that they exist. Despite that, she understands that the occult exists and is willing to work with them when the situation calls for it. An example is her being a part of IDEAL. She's pragmatic, logical, and resourceful. She prefers to look at everything with a scientific perspective, and will turn to the magic side only when there are no other choices.

She absolutely hates being called a child or short and will resort to violence when someone calls her short or a child, often kicking or punching them in the face. She also doesn't like to be called out on her brother's complex, and will constantly deny it despite knowing not to be true.

As a Kihara, she is remorseless in her pursuit for science and is willing to do inhumane experiments that only mad people would do. Unlike Eiichiro, she doesn't regret her actions and would gladly continue with her experiments if she were given the chance to. Recently however, she begins to tone down in her pursuit for science knowing full well that CERBERUS is pretty much a group of extremely smart individuals whose knowledge could be compared to that of the Tree Diagram (Azusa), or even surpass it (Eiichiro).

When it comes to her brother, she knows full well that they aren't actually related and doesn't feel any sort of guilt for loving her brother. She likes to keep Eiichiro to herself and is constantly searching for ways to stay with him, despite knowing that he brings a lot of trouble and that her pragmatic instincts are telling her to stay away from him. While she doesn't like being called out on her brother complex, she doesn't want her brother to ignore the signs of her brother complex. She is fiercely loyal and is willing to protect her brother at all costs, stated by Nana that she probably wouldn't enjoy a world without her brother.

## Appearance

Chinatsu is often mistaken for a little child in her middle school years, due to her extremely short stature and petite figure despite already being 19 years old. Something that she really doesn't like being mentioned. She has long dark-green hair that flows down to her hamstrings, light brown eyes and pale skin.

She shares a lot with Eiichiro in terms of appearance, the both of them always have this tired look in their faces and even tends to have this daydreaming look when she is not concerned with something. She also has her hair kept messy and unkempt, not really caring whether it is groomed or not and rarely combs it.

Like her adoptive younger brother, Eiichiro, Chinatsu likes to wear her white lab coat over anything she is wearing at the moment. However unlike Eiichiro, she doesn't just wear one type of clothing. She wears often wears casual clothes and mismatched shoes, which reinforces her childish appearance. The lab coat is also too big for her in which she has to fold the sleeves backwards, and yet she still suffers from what Akuta calls the *"moe sleeves"*.

## Powers and Abilities

### Genius Level Intelligence

Chinatsu is a Kihara, and as such has a natural affinity towards science and experimentation. She is a researcher and engineer for IDEAL, providing them with different equipment based on the missions they were assigned. She's devious and manipulative, using her knowledge of psychology to be able to induce a certain emotion or make use of another person's emotional weakness to her advantage. She has extensive knowledge in chemistry, as she was able to create chemicals that can control the blood distribution, cerebrospinal fluid, and others, in the brain to control the human mind in a similar manner to that of Shokuhou Misaki's **Mental Out** *(心理掌握 Shinri Shōaku, lit. Psychological Control)*. Her usage of the chemicals to manipulate the minds of others shows some degree of knowledge in neuroscience.

Due to being on the Dark Side of Academy City for so long, she has developed the ability to slightly predict what the actions her opponents will take in combat and can pick up on the signs of someone still having a trump card to play and see through people's deceptions through their mannerisms, the hope in their eyes and facial expression. She has also shown to have a combat pattern pattern consisting of controlling hammer-level destructive power on the microscopic level, allowing her to beat down a high level esper in a close quarters combat when enhanced with the Modelcase Processor Suit. As such, it can be stated that she is pretty efficient when it comes to dealing with espers by understanding their esper power and calculating different attack patterns that exploits the weaknesses of an esper's ability.

She is shown to be an extreme planner, capable of having multiple parallel plans that mostly end in the same outcome. She is also said to be an expert in manipulating people's 'hearts', using only words or hypnotic suggestions, making her enemies fear her and create a mistake if they panic. This, combined with her intellect also allows her to predict people's actions. Even against an expert assassin with weapons like Sunazara Kyoko, she was able to control most of the battle until she used Magic. Chinatsu is also able to apply self suggestion on herself to dilute pain, but she comments that it isn't perfect. Faith has even openly acknowledges that Chinatsu's skills at manipulating people can match the Level 5 ability of Mental Out.

Using Eiichiro's power as a reference, Chinatsu was able to develop skills in fine tuning an Esper's brain in order to bring their powers to the maximum. This was seen with her PARASYTERS, in that despite their power level being recorded at Level 1-3, they have performed applications that are stated to be of higher level. She has also displayed a level of skill in creating acoustic based technology, as seen where she was able to create a unique sound frequency that was specifically designed to agitate the brain cells of certain espers and put it in an immensely painful state of stress in order to make their powers run out of control. She has also shown the capability of analyzing and understanding various "abnormal" phenomenons brought about by magic and keep track of all the hundreds and thousands of different unique phenomenon brought about by it's scientifically impossible logic.

## Items and Equipment

### Cybertrons

**Cybertrons** *(サイバトロン Saibatoron, lit. Transformers)* is the name of the series of transforming vehicles given by the engineer and researcher of IDEAL, Kihara Chinatsu, who is an expert in mechanical engineering and a researcher of the Kihara Family. The Cybertrons are a series of specialized humanoid mechanical powered suits that can rearrange their mechanical components into a vehicle that they were modeled after. They are not sentient or automated, and as such must be piloted by a driver. The Cybertrons can be piloted by anyone whether be it magician, esper or an ordinary human as it doesn't require any form of AIM Diffusion Field or any form of magical power to use. It's fueled by specialized batteries that only Chinatsu can make, called the **"A11-S-21. PARK\_I7bH0"**.

The Cybertrons are a product of Chinatsu's research in developing powered suits that can be used for disguise, stealth and undercover work. Sunazara Kyoko typically uses the Cybertron Vehicles in her missions, as the vehicles are extremely advanced in terms of speed, power, efficiency and utility. The vehicles themselves can hold up to more than 4500kg's worth of baggage and is usually equipped with built-in defense systems and firearm artillery that can be used during high-speed road chases.

The Cybertron's powered suit mode has displayed to be equipped with **Hard Taping** *(発条包帯 Bane Hōtai, lit. Spring Bandage)* a military ultrasonic wave elastic taping which is primarily used to give Powered Suits higher mobility than a fully-equipped vehicle and allows the Cybertron to move at speeds greater than 10 times what a vehicle of Academy City can. The pilot of the Cybertron in Powered Suit Mode can still access the built-in defense systems and firearm artillery in combat. Chinatsu claims that the Cybertron can fight an entire military for several months without ever tiring. The Cybertron Power Suit also has a carbon layering over it's armor, allowing it to be as hard as diamond.

### Chemical Out

**Chemical Out** *(心理薬品 Shinri Yakuhin, lit. Mental Medicine)* is a series of customized chemicals created by Kihara Chinatsu to control the secretion of chemicals in a target's brain via the control of blood distribution, cerebrospinal fluid, and others, in the brain to control the human mind in a similar manner to that of Shokuhou Misaki's **Mental Out** *(心理掌握 Shinri Shōaku, lit. Psychological Control)*. The chemicals can be used in both gas or liquid state depending on the situation, although Chinatsu prefers to use it in gas mode due to it being easier to invade the brain, and it can affect a larger number of individuals.

When in combat, Chinatsu primarily keeps the chemicals in her utility belt and takes them out to either spray or throw the chemicals at her enemies, sometimes forcefully making them drink it. Certain combination of chemicals can be used to restrict the movements of people and effectively paralyze them in place, others can cause a neurocognitive deficit shutting down a person's brain functions, rendering them unconscious. She can also use the chemicals to prevent an esper from using their abilities by temporarily causing a disturbance in the brain and affect the Personal Reality. The chemicals can also be used to remove any physical sensation or temporarily suppress emotions.

The Chemicals can influence a person's dreams, emotions and behaviors by disrupting the chemical fluids in the brain, causing a person to act or feel differently than normal. Although it is shown that the effects are temporary and will not last longer than 24 hours. Using the same concept, she can also cause a person to hallucinate in all five senses to confuse them. It should be noted that it was Chinatsu who worsened the Mental Disorder of Amelia Barnes using these chemicals, normally the effects would only be 24 hours but with the **Operation Orb** (*演算宝珠 Enzan Hōju, lit. Operation Sphere)*, the worsened mental illness became permanent, implying that Chinatsu can use the chemicals to control a person's mental disorder to a certain degree.

The Chemicals can also cause the brain to go into a deep hypnotic trance, which allows Chinatsu to give preset commands, as well as effectively mind control them for a span of 24 Hours. In regards to memory, the chemicals can be used to remove people's memories by disrupting the neural cells, and extract memories from a person of the past year. Needless to say, the Chemical Out Set is one of the cases of reproducing esper powers without a Personal Reality.

### PARASYTER

**PARASYTER** *(パラシター Parashitā, lit. Parasite Clones)* is the term used to refer to the artificial humans created by Kihara Chinatsu. The PARASYTER is artificially created through chemicals, experimentation and body cultivation. Using a method similar to how Hazakura Kana cultivated the brains of espers in Academy City to create **The Brain Interactive Construct** *(脳波計算器 Noha Kesanki, lit. Brainwave Computer)*. Despite this, their appearance and their bodily functions of PARASYTERS are no different from regular humans. The PARASYTER Project was based on the Chemicaloid Project by STUDY and the Radio Noise SISTER Project, both of which required creating artificial espers for the organization's purposes.

The **NEST** *(ネストNesuto, lit. Incubator)* is a machine that was developed by Chinatsu with the purpose of mass producing the PARASYTERS, which can be done with a push of a button. The **Testament** *(学習装置 Gakushū Sōchi , lit. Learning Device)* was used to input information into their brains, and their physical bodies were grafted with chemicals to accelerate their growth rate to that of either teenagers or adults.

PARASYTER Clones are divided into **Higher Specs** and **Lower Specs**. The lower specs are used as grunts to do menial tasks for them. They are used to assist them in missions, be their gofers, conceal their operations, and destroy evidence, which includes collecting the corpses of the dead enemies (such is the case with the deceased corpse of The EYE's original incarnation). The higher specs are further divided into two sides, one for the Science Side and one for the Magic Side. The Science Side undergo the Power Curriculum Program and are given esper powers, the Magic Side have the fundamentals of magic inputted into their brain using the Testament Machine.

In every mission, at least two or three Higher Spec PARASYTERS are used to assist IDEAL or CERBERUS Members along with some Lower Specs. The Magic Side Higher Spec PARAYTERS typically aid the magicians of CERBERUS with the preparation of spell casting or if a synchronized chant is required. As displayed by Felicity when she was able to use the **Gregorian Chant** *(グレゴリオの聖歌隊 Guregorio no Seikatai, lit. Gregorian Choir)* to achieve Holy Bombardment Magic with her as the antenna for the spell by preparing 3000 PARASYTERS to pray simultaneously.

The PARASYTERS are also connected together within a specialized Brainwave Network that can acts as a Supercomputer similar to that of the Brain Interactive Construct, although slightly inferior to the Construct in terms of calculation prowess. The **PARASYTE Network** *(寄生虫ネットワーク Kiseichū Nettowāku, lit. Parasite Network)* is easily superior in terms of mobility, and is superior in terms of it's ability to defend itself and stay active when damaged (as the Brain Interactive Construct cannot regenerate and must require extensive repairs to make it work again, whereas the PARASYTE Network can simply be regenerated by producing more PARASYTERS). Unlike Hazakura Kana, who made herself the administrator of the Brain Interactive Construct. Chinatsu didn't make herself the administrator of the PARASYTE Network. Instead she connected her customized phone and the Modelcase Processor Suit to the PARASYTE Network, allowing her the advantage of having access to the vast calculation processing of the Network without any of it's side-effects.

### Modelcase Processor Suit

The **Modelcase Processor Suit** *(モデルケース プロセッサスーツ Moderkassu Purosessasūtsu, lit. Complete Body Processor)* is is a special full-body strengthening suit developed by Kihara Chinatsu and Sunazara Kyoko. The Modelcase Processor Suit makes use of electric potential elastic tape, hard taping and motors to enhance the wearer's capabilities. It utilizes the same Calculate Fortress Material used in the Windowless Building, which partially reproduces Accelerator's vector control to absorb, disperse and soften impacts.

The suit has a large number of sensors, including cameras and microphones, which monitor the environment around the wearer, enabling them to sense light, sound, and smells exactly the same as always, and possibly allow them to view things beyond the normal human senses such as gasses and electromagnetic waves. Sensor-covered gloves allow them to feel through touch. As well as external sensors, the suit also has internal sensors which monitor the wearer's condition. It can read electrical signals and potential differences on the exposed surface of wearer's skin.

There are irregular lines of pale light along the gaps in the armor, possibly made by LEDs or OLEDs, which slowly blink on and off. The lights change color depending on the level of danger to the wearer in the immediate vicinity, from blue when safe to yellow and then finally to red.

A display on the inside of the visor shows the wearer their surroundings in conjunction with the sensors, together with any additional information the user requires. As well as icons for active functions or warnings and labels assigned to surrounding individuals or objects in the surroundings, the display can also pop-up windows with maps, data from the suit sensors, instructions from the Bank's database and other information to support the wearer, or a simple puzzle game for them to pass the time. Warning icons concerning immediate dangers are red, while less urgent warnings are yellow (such as a heart-shaped icon which signifies rising stress). In manual mode, colorful numbered circles are overlaid on the surroundings, like a pattern from a dance game, to guide the wearer through optimum paths, evasion patterns and combat techniques. If the users deviates from the markers, a red 'unrecommended action' icon is shown before the route is recalculated. Similar markers may also be used for predicted landing points.

The suit apparently lacks an external port for cables, though it can connect to networks wirelessly. With enough modification by Chinatsu, the Modelcase Processor Suit is connected to the PARASYTE Network. Enabling the user to access the vast computation process of the Network, and use it to simulate several combat patterns.

With the electric potential elastic tape, hard taping and motors as well as the Calculate Fortress, it can deliver blows strong enough for the shockwaves to blow steel building beams away and make the armor glow red like a steel beam fresh off a blast furnace. The suit can make movements on its own in response to the user's thoughts and in manual mode, by moving according to the markers presented on the visor, like entering a simple combo command in a fighting game, the user can perform potent martial arts moves capable of throwing a 1-ton armored truck through the air or easily avoiding full-auto fire from multiple directions without warning, even if the user has no knowledge of how to do so themselves.

The Modelcase Processor Suit also possess a vast amount of arsenal comprised of various parts and components which are assembled around and connected to the suit. Weapons including: guns, cannons, swords, spears, molecular vibration electromagnetic wave emitters, catapults, lasers and excitation emission rods for them, missile pods with precision-guided missiles, plasma cannons, bunker busting and excavation drills, plasma blades, liquid weapon turrets with acid sprayers, flamethrowers and liquid nitrogen emitters, gatling guns, rapid-fire cannons and a large caliber railgun, of the type carried on railways and meant for destroying fortresses.

Among the unit's arsenal is a tactical armor-piercing drill, made of tungsten steel and running through the entire unit from front to back, dozens of meters long. Achieving speeds using the same electromagnetic acceleration as a railgun or mass driver, it produces immense destructive power through its rotation, being capable of breaking into an underground silo or destroying a military base. The drill's rotation can also be used to transmit extremely high-speed high-frequency vibrations.

## Trivia

Kihara Chinatsu is the adoptive sister of Kihara Eiichiro and was partially inspired from Jules Verne's 1870 book *Twenty Thousand Leagues Under the Seas*' protaganist, Captain Nemo. Kihara Chinatsu was originally envisioned to be a teacher character but that was eventually scrapped for a sister character that has the combination of an elder sister feeling with that of the little sister appearance.
