Emiko Homura

"*Anyone can become a hero if you feel the desire for peace in your heart!*"

**Emiko Homura** (穂(ほ)村(むら)笑(えみ)子(こ), *Homura Emiko*?) also known as **Mercury** (マーキュリー, *Mākyurī*?) is one of the Foreign Trio filling the role of "Hero". She is a student of U.A in Class 1-B.

## Appearance

Emiko Homura is a teenage girl of average feminine height with an athletic body. Her hair is white in colour and is tied to a ponytail in the back, she also sports a hair band that is red with a white edge, the irises in her eyes are also of a red colour.

Emiko's hero costume takes inspiration from a traditional tracksuit, featuring a form-fitting silhouette that enhances agility and freedom of movement. It comprises a jacket and matching pants.

The jacket boasts a sleek and asymmetrical design. The front zip closure is concealed to maintain the costume's seamless aesthetic. The high collar rises gracefully to protect Emiko's neck. It is lined with a soft, moisture-wicking material to ensure comfort during intense physical activity.

The tracksuit is reinforced with light armor in key areas to provide protection without compromising mobility. The armor is made of a durable composite material, blending seamlessly with the tracksuit. It covers the chest, shoulders, elbows, knees, and shins, providing essential protection without weighing her down.

To aid lin Emiko's flight and control her speed, an intricately designed nitrogen propulsion system is incorporated into the costume. The system is seamlessly integrated into the costume, with discreet thrusters positioned on the forearms, calves, and back. These thrusters are barely noticeable when not in use. The propulsion gauntlets and boots feature streamlined compartments that house the nitrogen propulsion mechanisms, blending seamlessly with the overall design while providing necessary protection.

## Personality

When she is around her friends, Emiko is a mischievous, sarcastic and eccentric, yet good-natured and friendly girl, who is very intelligent but lazy, which is why her grades are uneasy. However, Emiko is very good at pulling an "all-nighter" and she always crams for tests the night before they happen, instead of studying ahead. She always teases her friends in a funny type of way, such as if they like someone.

But when she is fighting a group of villains by herself, she becomes brutal and maniacal, her once playful and eccentric demeanor transforming into a tempestuous storm of unyielding fury. This was shown when she was ambushed by a gang of villains that she had took down a few days ago. Ambushed and outnumbered, she would go on to stomping over her assailants with a psychotic grin and wide eyes. With her heroic qualities out of the window, fighting like an unrestrained berserker.

## Abilities

**Overall Abilities**: Emiko has proven to be one of the strongest students in Class 1-B, earning first place in the Quirk Apprehension Test, while placing third place in both the U.A. Entrance Exam and the U.A. Sports Festival.

Emiko capitalizes on her exceptional agility and speed. She employs a dynamic and fluid fighting style, utilizing her athletic prowess to swiftly close the distance between herself and her opponents. Emiko's precise control over her buoyancy enhances her mobility, allowing her to dart around the battlefield with remarkable grace. Once engaged in close quarters, Emiko's melee attacks are characterized by a combination of swift strikes and acrobatic maneuvers. She utilizes her quirk to augment her strikes, adding power and impact to her blows. Emiko's adeptness in hand-to-hand combat is further enhanced by her natural athleticism, enabling her to perform intricate evasive maneuvers, grapples, and devastating close-range techniques. Her proficiency in acrobatics grants her the ability to deliver unpredictable attacks from unconventional angles, keeping her adversaries off balance.

Using Buoyancy Shift, she can will increase the buoyancy of her own body momentarily, granting her the ability to evade or dodge attacks more effortlessly. By manipulating the weight of her strikes, Emiko adds power and impact to her punches, kicks, and weapon strikes, increasing the damage she inflicts upon her opponents.

In ranged combat, Emiko relies on her precision to maintain control over the battlefield. She assesses the situation and utilizes her Buoyancy Manipulation to manipulate the environment and create obstacles for her opponents. By subtly altering the buoyancy of objects, she can redirect or impede projectiles, diverting them away from her or using them to her advantage. This ability allows her to create a strategic advantage by limiting her opponents' options and disrupting their attacks.

When it comes to battlefield adaptation, Emiko excels at adjusting her plans and force distribution based on the evolving circumstances of a fight. She possesses the ability to gauge the changing dynamics of a battle and make necessary real-time adjustments to ensure the optimal allocation of her team's resources. Emiko's astute observation skills and strategic thinking enable her to identify critical moments where the distribution of force can shift the tide of a conflict. She can make quick decisions regarding the deployment of her allies and herself, strategically positioning them to maximize their effectiveness and create advantageous situations.

### Quirk

**Buoyancy Shift** (浮(ふり)力(ょく), *Furyoku*?): Emiko's Quirk allows her to manipulate the buoyancy of herself and her surroundings. It allows Emiko to enhance, diminish, redirect, or otherwise nullify the buoyant force on an immersed object, whether in air, water, or another fluid, and can cause it to float, sink, appear lighter, heavier, or experience a neutral buoyancy.

Emiko has a strong grasp on the applications of her Quirk, something that was acknowledged by Edgeshot, a top Pro Hero; not only can Emiko generate negative buoyancy attacking, she can generate positive buoyancy levitate and navigate through the air, allowing her to fly at her opponents without giving them time to react, as well as evade incoming attacks, even while in the air. She can neutralise buoyancy can also be used to defend against attacks, walk on water by fiddling with its surface tension, and throw large objects such as entire ships by making it buoyant.

### Ultimate Moves

* **Variable Buoyancy** (可変浮力, *kahen furyoku*?): Emiko can finely control the buoyancy of objects and herself. She can adjust the density of air and water in her vicinity, enabling objects to float, sink, or hover in mid-air. This control allows for precise manipulation of her environment, granting tactical advantages in both offense and defense.
	+ **Sinking Helium** (沈むヘリウム, *shizumu heriumu*?): After making contact with her opponent, Emiko charges them with positive buoyancy, making them fall to the sky as if gravity has been reversed. Once the opponent is just barely out of her reach, she inverts the charge to become negative buoyancy, hurling then to the ground at a velocity faster than gravity.
* **Sonic Fluid Resonance** (音波流体共鳴, *onpa ryūtai kyōmei*?): By carefully modulating fluid properties, manipulating the airflow, and altering the density, temperature, and composition of the surrounding fluid medium, Emiko can generate and control resonant frequencies within gases and liquids. The resonant frequencies generated by her manipulation of fluid dynamics lead to a rapid amplification of energy within the medium. This energy builds up as vibrational waves travel through the fluid, colliding and reinforcing each other. She can direct and focus this amplified energy to specific targets, unleashing powerful sonic vibrations upon impact.
	+ **Structural Disruption**: The intense sonic vibrations generated by Emiko's quirk can destabilize the molecular structure of objects or materials within the fluid medium. This can lead to fractures, cracks, and eventual structural failure, allowing her to dismantle or destroy obstacles, barriers, or enemy fortifications.
	+ **Disorientation and Incapacitation**: Sonic Fluid Resonance can disrupt the equilibrium and sensory systems of opponents. By vibrating the fluid medium surrounding her foes, Emiko induces disorientation, dizziness, and impaired motor functions. The resulting sensory overload can render opponents incapacitated or significantly hinder their combat effectiveness.

* **Density Shields**: In the case of air, Emiko can decrease the buoyancy of the surrounding air in a localized area. And by doing so, the air becomes denser and more resistant to the passage of objects or attacks. This results in the creation of a shield that acts as a barrier against projectiles or physical assaults. Similarly, when it comes to water, Emiko can increase the buoyancy of the fluid to generate a protective bubble or barrier. By increasing the buoyancy, she can make the water less dense and more prone to supporting the weight of objects. This allows her to create a shield of floating water that can absorb or deflect incoming attacks.
* **Healing and Regeneration**: By using Bernoulli's principle, Emiko can create areas of low pressure around wounds or damaged tissues to promote increased blood flow and oxygenation to the affected area. This increased circulation aids in the delivery of nutrients and removal of waste products, fostering faster healing and tissue regeneration. Additionally, heightened blood flow aids in the removal of waste products and toxins from the injury site and accelerate the closure of the injury. Bernoulli's principle can also be employed to create a gentle suction effect, which can help bring the edges of the wound together, facilitating faster and more effective wound closure.

## Equipment

**Inner Mercury**: Emiko's tracksuit is constructed from Lycra infused graphene, a durable and lightweight synthetic fabric that allows for unrestricted mobility during combat while providing thermal conductivity and excellent moisture-wicking properties. The silver color not only gives it a distinctive appearance but also aids in reflecting and dispersing light, making her less visible in certain environments.

**Outer Mercury**: The costume incorporates lightweight armor in specific areas to balance protection and mobility. The armor panels are made of a combination of carbon fiber and Kevlar layers, offering exceptional strength, impact resistance, and defense against projectiles and cuts. Vital areas of the armor contain ceramic composite inserts made of boron carbide, providing superior ballistic protection by effectively dispersing impact force. Joints like elbows, knees, and shoulders are reinforced with aramid fiber layers, enhancing the costume's durability, strength, and resistance to impacts and abrasions. Impact-absorbing EVA foam is strategically positioned in key areas to reduce the impact's intensity. Additionally, memory foam is integrated for added comfort, contouring to Emiko's body shape and providing optimal cushioning.

**Dynamic Nitrogen Propulsion Attachment** (動的窒素推進鎧, *Dōteki Chisso Suishin Yoroi*?): The costume features a nitrogen propulsion system that utilizes a combination of miniaturized jet engines and advanced control mechanisms to generate thrust and enable controlled flight.

The costume features six miniaturized jet engines strategically placed on the back, forearms, and calves. Two jet engines are positioned on the upper back region of the costume, symmetrically on both sides of the spine. These back jets provide the primary thrust for forward propulsion and help stabilize Emiko during flight. Two smaller jet engines are located on each forearm of the costume, near the wrists. These forearm jets assist in maneuverability and control by generating thrust in different directions, allowing Emiko to adjust her flight path and perform aerial maneuvers. Two additional jets are placed on each calf, near the lower leg region. These calf jets provide additional thrust and stability during flight, aiding in elevation control and maintaining balance. These engines are designed to harness the power of nitrogen gas as a propellant. Nitrogen is stored in high-pressure canisters integrated into the costume.

Each jet engine is equipped with precision control valves to regulate the flow of nitrogen gas and manage the thrust. These valves enable Emiko to precisely adjust the intensity and direction of the thrust, granting her meticulous control over her flight. The control valves are multipoint valves, offering multiple adjustable settings to vary the thrust intensity. This feature allows Emiko to independently fine-tune the output of each jet engine, providing her with flexibility in controlling flight maneuvers and speed. Additionally, the control valves are integrated with built-in sensors that continuously monitor the nitrogen gas flow and pressure in real-time. These sensors ensure accurate and responsive control, enabling the hero to make immediate adjustments based on her flight requirements and environmental conditions.

The costume's control valves are connected to a central control mechanism, which receives input from Emiko's movements and gestures. This mechanism interprets her desired adjustments in thrust and transmits corresponding commands to the control valves. By integrating with motion sensors throughout the costume, the control mechanism captures real-time data on Emiko's body movements, enabling precise control over flight maneuvers and adjustments to the nitrogen propulsion system. Emiko can utilize a control interface to customize the intensity and direction of the nitrogen thrusters, while the control mechanism translates her input into corresponding adjustments in the control valves of the jet engines. To maintain stability during flight, the control mechanism continuously analyzes data from gyroscopes and accelerometers, automatically adjusting the thrust output of individual jet engines to counterbalance any deviations or disruptions in Emiko's flight path. This seamless linkage ensures that Emiko's intentions are accurately translated into precise control over the propulsion system, providing her with a smooth and controlled flying experience.

The apparatus is powered by a compact, high-capacity energy source that fuels various components, including the nitrogen propulsion system, control mechanisms, and integrated technology. This power supply enables sustained flight capability and operational longevity. The battery cells within the power supply are arranged in a compact and densely packed configuration. To achieve a higher energy capacity in a smaller form factor, high-energy-density lithium-ion batteries are utilized. The costume includes a docking station for recharging the power supply. Instead of having a centralized power supply in a single compartment, the power distribution components are spread throughout the costume. This design allows for even weight distribution and reduces bulk concentration in one area. The integration of a power management system enhances efficiency by effectively managing and distributing the available energy from the power supply. It dynamically allocates power resources based on real-time demands of subsystems like the nitrogen propulsion system, control mechanisms, and communication systems. By analyzing power consumption patterns and profiling, it predicts and adapts to varying power demands, ensuring optimal utilization. Intelligent routing algorithms determine efficient pathways for power distribution, minimizing energy losses. Sensors and monitoring mechanisms provide feedback on power levels, enabling informed decisions for load balancing, system protection, and power conservation modes.
