**Chiba Rasen** (螺旋(らせん)千(ち)葉(ば), *Rasen Chība*?), also known as **Azure Spirit** (アズレ・スピリット, *Azure Supiritto*?), is a student of Class 2-A at U.A. High School.

Born as a child of two pro heroes, Chiba has been raised on high standards. His father, Metsushin, taught him what is necessary to survive and his mother, Kunihime, the kinder things of life.

## Appearance

Chiba is a tall young man, with a semi-ovalish face. He has messy brown hair that holds overhanging pieces at the front and a large spike of hair that sticks up in the back. His eyes appear visibly as lines, but he can see well from close distances, but requires glasses which are thick enough to magnify his eyes, which has yet to be seen. His eyebrows are quite thick and he has curved fangs which protrude the far ends of his lips, resembling close to a japanese demon, an oni.

During the later half of his first year in U.A., he grew two blue horns, around 5 inches in length. They appear to made of a crystal or keratin. Whenever he activates his quirk, the horns can conduct electricity through them. During his second year of school, both of his horns have grown further, but one was broken off during a tournament at the Kakusei Dojo. This event made his horns offset with his left one being a little longer.

Chiba's physiology has a high density composition, with his muscles weighing double of the average individual. Over the years of training under his father, his body has naturally begun to tone and in turn his weight increased. His tongue is uniquely shaped to be forked in a trident manner, having three tips to it, he can also touch his nose with his tongue. On his abdomen is a spiraling birthmark which is inherited by all those of Rasen lineage.

With the years of his intensive training, Chiba has gained a variety of skills, but at the cost of his body's condition. Over the course of 10 years, Chiba has gained an assortment of scars that cover his body, these were mainly healed by his mother, Kunihime. A majority of his scars cover his torso, being caused by broken bones, cuts, and more. On his left pec, over the heart, is a scar shaped as a lightning strike; this was gained through his training to further empower his abilities.

Instead of one heart, Chiba possesses a second one located behind his right breast. His blood contains a higher number of copper than iron, as does the average human body, causing his blood to bleed blue- as well as correspond to his electrical aspect of his Quirk. His basic survivability differs from normal, as he can last about a month without food or water.

At U.A., he sports a standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt and dress pants, along with a red tie which he keeps proper and straight. He wears plain black shoes worn by the majority of the student body, but will switch into a type of sneakers that is worn by shaolin monks. He also wears his iconic gray scarf with every outfit he has.

Chiba's original hero costume is a relaxed fit wear which consists of a long, black jacket, gray belt, fingerless gloves, shin guards, and his scarf. He also wears a demonic, blue mask. On his arm is a special equipment he uses to gauge the power level of his Quirk, this being the Caliber Gauntlet. His scarf, when inverted, shows a white fang-like pattern on it; there are two dots in the center of the scarf, indicating the support company that designed his costume.

At the Kakusei Dojo, located in Kameyama, Mie, Japan, and ran by his father. Chiba sports a special uniform which resembles a traditional shaolin kung-fu uniform. While the average uniform consists of a black material with an orange line crossing it, Chiba's uniform carries a blue line crossing it and a special design of a teeth-like pattern of silver over his left shoulder. The white obi belt that goes across his waist consists of 1 thick black line and 2 thin black lines, stating that he has reached Hachidan in the dojo.

## Personality

Chiba is an intellectual person who holds a friendly encounter to those he interacts with, appearing approachable and comforting to some. He found interest in learning how to interact with others; especially through combative training, as he aims to understand them through the manner they fight in. His intelligence is expressed through his academics and quick thinking skills, allowing him to apply strategies for many scenarios.

Though even with this kind nature of his, he becomes self-conscious about his appearance. During his youth he held tucked in his fangs into his mouth after classmates had poked fun of him for it. To further hide this he wore a large scarf to cover the lower half of his face. When interacting with strangers, he often seems to stare into people's eyes, though while his own aren't visible, the sensation of being watched often looms over those he stares at. With his fascination about learning about people, he takes notes of people's personalities and quirks.

Chiba can prove a bit stubborn at times, especially when he becomes determined. He's quite assured of his own skills and has a bad habit of attempting to trigger certain emotions of his opponent when he is in a fight, sometimes his own classmates to improve their activity in a spar. Though in turn, his own competitive-side shows and in fighting he can get quite intense. When fighting intensely, his mind empties to focus on fighting, making him a bit impatient and battle-hungry.

## Abilities

**Overall Abilities**: Chiba is known for his intellect and variety of skills. By himself he has proven to be a remarkable strategist, with vast knowledge on topics ranging from tactics, education, and survival skills. Studying tactics for years, he's found to create advantageous scenarios for him and his allies.

Even without his Quirk, he has shown to be a formidable opponent in hand-to-hand combat. After training intensely with his father, a pro hero as well as one of the top martial artists in hero history, he has shown to be able to display vast forms and motions of different fighting styles.

In a brawl, Chiba doesn't naturally hold back his attacks, each blow he deals at full force given how his Quirk requires him to do this. During a battle he'll study his opponents and use the speed and strength from his Quirk to overpower them. He fights efficiently and but may not know when to stop himself.

**Hand-to-Hand Combat**: Under intense training from his father, Chiba uses a variety of martial arts and skill sets in both his training and combat. When fighting others with unusual styles, he'll replicate techniques to surprise his opponent. As long as it's physically possible for him, he'll be able to copy it to some degree.

* **NRH Training**: Said to be an ultimate training course, Chiba has taken part of it during his study of Kakuseiken under his father. These special courses have honed his skills to great extent, and can be visibly seen through the many scars on his body.

* **Enhanced Strength**: Chiba is known to be quite formidable by himself. His intense training that has granted him this.

* **Pain Endurance**: Chiba has proven himself resilient, and able to take a blow without flinching. During the New Years Event, he was shot in the shoulder by a bullet, but wasn't bothered by the pain.

* **Kakuseiken** (覚醒拳, *****Kakuseiken*****? lit. Awakening Fist): Under Metsushin, Chiba uses a form that excels into striking critical points of the body. Chiba's footwork is kept light and nimble for swift movement. Attacks are explosive in nature- forcing the body to move quick and powerful. Chiba has learned to do many techniques taught in this art.
	+ **Raiken** (雷拳(らいけん), *****Raiken*****? lit. Thundering Fist): (Formerly known as "Ikazuchiken") Chiba's personal adaption to his father's Kakuseiken, focusing on using multiple aspects of his Quirk with his attacks. At later stages of his Calibers, he'll infuse his attacks with electricity to attempt to stun his opponents. Though while it grants him a powerful arsenal, it has a dire cost to the body.

**Genius Intellect**: Chiba has proven to be exceptionally intelligent, gifted with a highly educated and strategic mind. His analytical skills are strong and are able to deduce an enemy's weaknesses and combat style quickly. He'll aid his classmates in where they are strong or where they are weak. Academically speaking, he is one of the smartest students in the class, going beyond his natural talent by adding hard work to it.

**Detection**: Chiba has developed the ability of sensing an "aura" around people or an individual. Commonly, this is similar to sensing levels of intimidation that emit from someone or intent of doing something. He's able to determine best by looking people in the eyes.

### Quirk

**Affinity** (強化, *Kyōka*?): Chiba’s Quirk allows him to increase his physical strength and reflexes through accumulating energy by physically conflicting with something. Making it a powerful Quirk in terms of combat. Affinity works in ‘Calibers’, measured stages of his prowess. To increase into a higher caliber, he can strike a target with any part of his body in order to pass a threshold, which leads into a new caliber. If he fails to pass or keep consistent pressure towards a threshold he'll end up reverting a few calibers. Each threshold requires more kinetic force to pass than the previous.

Upon initial activation, Chiba's blood begins to heat to where it appears as a blue vapor emitting form his skin. This aura will sharpen and create electrical sparks the higher Caliber he is in. Originally he would be required to start from Caliber 1 and move onward from there, but through training in youth he is able to jump to Caliber 4. When he jumps towards a higher Caliber, he'll release a sudden spike of energy for less than a second, the energy will quickly level off to a Caliber he can maintain. He is currently able to reach Caliber 22 by his 2nd Year at U.A. High. While activated, his body will tense and form even denser muscles. Once he reaches a certain Caliber, his aura will begin to emit electrical sparks of weak voltage.

Through variations of training, Chiba plans on figuring out how to reach greater Calibers. Through physical training he continues to tone his body to be capable of holding that energy without instantly damaging it. He explores meditation and forms of Kuji-ins to focus on controlling the energy. The last method, he has discovered that self-inflicted damage can also generate a boost in energy, he attempted was near-fatal, leading him to have this as a last resort.

When entering his Caliber limit with his Quirk, Chiba will seemingly focus on his opponent and fight with growing intensity and drive. Becoming hostile and eager for the fight. His horns grow brightly with electrical sparks flying from them, his skin turns a tint of blue as his scars begin to glow with his aura, his appearance overall growing more demonically.

After deactivating his Quirk, he'll experience a subtle to large drain on his body and stamina. The loss of physical aspects correspond to the amount of energy he gained at the peak Caliber when in use. If he keeps his Quirk activated for long periods of time, at random, his bones may begin to fracture or his organs bruise from the pressure of his body and energy; damaging his internal structure. Externally his muscles may shrink and smooth out, followed by experiencing similar symptoms to that of blood loss.

The time limit for Chiba to gain power shortens with every Caliber he enters. By jumping to a Caliber off the bat, the time gap will also be shortened as if he had newly entered the stage. His power, proving highly rewarding if he can keep the pressure on his target, can also decrease as fast, if not faster, as he had gained it if he fails to do so.

### Super Moves

* **Azure Spirit Unstoppable** (紺碧 精神 安無嶺過武瑠(アズレ スピリット アンストッパブル), *Azure Supiritto Ansutoppaburu*?): Chiba achieves his full power, maximizing speed and strength to his limit. This is more of a state than a supermove. Currently this is achieved at Caliber 20+.
* **Demon Twister** (悪魔 螺旋 状 槍(デーモン・トウィスター), *Dēmon Tou~isutā*?, lit. "Demon Spiraling Spear"): Chiba moves his forearm in a spiraling motion and builds up energy into his fist. Once he closes the distance between him and his opponent, he'll strike in an unexpecting pattern and punch. Being hit by this attack would send his opponent spiraling away. This technique has been passed down to each child of Rasen lineage.
	+ **Demon Twister - Eye of the Storm** (デーモン・トウィスター・アイオブザーストーム, *Dēmon Tou~isutā Ai obu zā Sutōmu*?): Chiba, at Caliber 15+, spins his fist around and tenses his muscles, by punching fast enough, he can utilize the air pressure into a powerful range blast.
* **Flying Raijin** (飛雷神, *Hiraishin*?): By activating his Quirk, Chiba uses a momentarily spike in energy to burst towards a direction. He’ll use this momentum to cover large distance in less than a second. If possible, he’ll kick his opponent once he’s close enough. He can use this again in a higher Caliber, but he'll revert by one Caliber after using it.
	+ **Flying Raijin - Thunderstorm** (飛雷神 雷雨, *Hiraishin: Riau*?): Chiba adapts the move to dash towards a group of targets at high speed. He'll then use a series of spinning attacks to hit each one that are in close proximity or are in the direction Chiba moves in. He'll revert two Calibers after using it.
* **Demon Twister Flying Raijin Combo - Thousandfold Roaring Spiral** (サウザンドフォールド・ローリング・スパイラル, *Dēmon Tou~isutā Hiraishin Konbo Sauzandofōrudo Rōringu Supairaru*?): A move which Chiba can use at Caliber 20+. Using a combination of his Flying Raijin and Demon Twister, which involves Chiba dashing toward his opponent in a circular motion to create a drill. After arriving near the target, Chiba will pull back his arm and use the momentum to strike and release a mass impact of energy.

**Raiken** (雷拳(らいけん), *****Raiken*****?): Chiba's personal adaption to his father's Kakuseiken, focusing on using multiple aspects of his Quirk with his attacks. At later stages of his Calibers, he'll infuse his attacks with electricity to attempt to stun his opponents. Though while it grants him a powerful arsenal, it has a dire cost to the body.

* + **Thundering Fist - Squall** (雷拳(らいけん) 突風(とっぷう), *Raiken Toppū*?): Chiba bolts around the opponent in an unpredictable pattern, then he'll perform a chopping motion towards the opponent's neck or shoulder.
	+ **Thundering Fist - Tempest** (雷拳(らいけん) 怒涛嵐(どとうらし), *Raiken Dotōrashi*?): Chiba jumps while spinning his body to build up momentum and delivers a devastating kick, the longer he spins around the more energy he'll transfer in the kick.
	+ **Thundering Fist - Echo** (雷拳(らいけん) 電光の響(エコー), *Raiken Ekō*?, lit. "Sound of Lightning"): Chiba feigns an attack and quickly shifts his position to strike again.
	+ **Thundering Fist - Lightning Sprite** (雷拳(らいけん) 稲妻 上昇刀(ライトニング・スプライト), *Raiken Raitoningu Supuraito*?, lit. "Lightning Rising Sword"): Chiba dodges his opponents attacks as he closes the distance between them to deliver a powerful uppercut.
	+ **Thundering Fist - Thunderbolt** (雷拳(らいけん) 稲妻 落下斧(サンダボールト), *Raiken Sandāboruto*?, lit. "Lightning Falling Axe"): Chiba approaches his opponent from either the side or above and performs a devastating axe kick.
* **Teikeigyo** (霆契霅(ていけいぎょう), *Teikeigyō*?, lit. "Lightning Promises Thunder"): Chiba’s Final Resort, by striking one of his hearts to stop it, he was able to jump to Caliber 25. Though with these conditions, he is very limited on what he can do, such as attacking once. He is capable of moving in a single direction at incredible speeds that covers a long distance. If he is able to successfully strike his target, the damage will delay for a few seconds before the pent-up energy is released and inflict massive damage. Chiba will collapse before this happens and would be unable to heal any damage that had taken place. During Chiba's original attempt, his body failed to properly control the energy and by consequence nearly killed him. His mother was able to use her Quirk to heal his damage heart, but couldn't do much about the scars left over. She states that if he tries this again she wouldn't be able to heal the heart he sacrifices.
