Shira Okumura

Shira Okumura (奥村 詩音 Okumura Shira?) is the younger sister of Hotaru Okumura and elder, fraternal twin sister of Kanao Okumura. She is the daughter of Elizabeth Liones and Rin Okumura, making her the granchild of the Supreme Diety and Satan.

Appearance
Shira is a petite young girl with fair skin, visibly large, prominent fangs, and sharp, claw-like nails that fade to red where they point. Her hair is long, black and reaches just below her waist, turning a flame-orange color as it passes her elbows, and appears to be crimped into large, straight ridges, worn side-swept drastically to her left. She has soft-looking, pale pink eyes that appear a lighter color around the rims of their irises, slanted downwards towards the sides of her face and framed by notably long eyelashes, the pupils of which can appear slit as she transforms. According to Hotaru Okumura, Shira was known as a great beauty in their home town.

She wears her mother's a light pink kimono with a hemp leaf pattern, the lining a paler pink, with a red and white checkered obi and a thin piece of orange thread looped and knotted around her waist, another band of green above it. Over this, she sports a long, dark brown haori that reaches past her knees, as well as pink zori sandals and white socks, wrapped with thick pieces of black material. Shira also wears a small pink ribbon to the left of her head, to keep her hair out of her face, and the bamboo gag Yukio Okumura gave her, which is secured around her jaw with a strip of red cloth.

In her full demon form, Shira grows a short white horn on the right side of her forehead (similar to Kanao), and a vein-like pattern appears around her left eye, but her most striking new feature is the red and green vine-like pattern that covers her skin, circling around her arms, legs, and chest.

Personality
Shira is a kind and caring girl who thought of others before herself much like her siblings. Additionally, she is a responsible elder sister to her siblings and often puts their needs first rather than her own. Which supports her role as the older twin. Shira is, however, not afraid to get in harm's way, protecting her friends from Demons even after being returned to a human-esc state. It is also shown that Shira's humane, laid-back demeanor supports this fact after Hotaru apologized to her.

Shira she has been seen to cry when sad and smile when happy, but in general she appears more detached than her human cohorts, a trait she inherited from her mother, although she is still much calmer and less malicious than most Demons.

Shira appears to also be rather brazen, and does not seem to fear fighting; she fiercely guards her siblings as well as her allies. She has also developed a strong willpower, which can be seen through her refusal to consume human flesh or blood, even in cases of extreme injury or exposure to human blood, which can be seen when she refuses Arthur A. Angel after he attempts to lure her into biting him with his blood. Her strong willpower is shown when she willingly leaps in front of Bon to protect him from her own sister, who's power had gone out of control. Though she could have been killed, Shira did not hesitate.

Demon Abilities

 * Size Manipulation: Upon being a demon, Shira displayed the basic ability to change and alter her body's size and height. She was able to shrink herself into the physical size of a small child in order to fit inside a small box or a basket in order to hide from sunlight when traveling through the daytime with Hotaru and could enlarge herself into a much bigger form, in order to be able to battle against Demons.
 * Power Restoration: Shira's most defining trait as a demon is her ability to continuously restore her power, without consuming any human life as it is the normal method for most demons. Instead, she recovers her strength through mere sleep, another ability she gained from her mother.
 * Power Growth: As a subset of the above, Shira has shown to be able to grow stronger without any training or consuming humans. This ability is shown to trigger even in the midst of battle and with huge boosts. The greatest evidence of this was during her battle against Susamaru where her foot was blown by the temari demon's attack, but after regenerating she was able to face her in an even match kicking the ball and eventually surpassing her. Shira has shown to have powered up considerably as time passes.


 * Enhanced Strength: Despite never being formally trained, Shira's naturally enhanced physical strength allows her to easily fight against demons, however, due to being untrained, Shira instead relies on simply kicking her opponents or overwhelming them with brute strength instead. Her kicks allow her to sever Demons head with ease, or to kick down a door. Her strength is extremely high for a Demon who has never eaten a human, with her strength being able to match even that of and Upper Rank Demon, even some of the Eight Kings.


 * Enhanced Regeneration: Shira possesses a tremendous regeneration ability that enables her to restore severed limbs within seconds. The true nature of this ability is solidifying her blood from her severed body parts that she could manipulate at will. Her regeneration ability is shown off during her fight with Daki, where she regenerated her severed limbs at the speed and proficiency of an Upper Rank, even faster than her father.


 * Demon Transformation: When Shira is in a dire situation, she can transform into a full demon, with demon crests, that appear as vine tattoos, circle her body, her veins popping out and a single horn protruding from her right forehead side. This form enhances Shira's fighting ability, at the cost of her becoming more demon-like, including the need to feed on human blood. So far, the only way she could revert back to normal is to have someone (in her case, her mother) sing her a lullaby. During the Exorcist's fight against Lucifer, Shira manages to control this form at will.
 * Sunlight Resistance: Per her goddess heritage, Shira developed immunity from sunlight, now being able to completely walk and go about in the daytime without being burnt to ash, unlike her fellow demons.
 * Exploding Blood ( Bakketsu?): Shira can ignite her blood, turning them into engulfing flames. Although they are not Satan's flames as they are not blue, they are extremely powerful non the less. She is capable of controlling her flames into being lethal or non-lethal at will. Shira is seen to be using her blood to heal others' wounds as needed. However, these flames only affect Demons, like Rui's threads or Gyutaro's poison.


 * Holy Water: Despite being half-demon, Shira is immune to holy water, as such it doesn't affect her and acts as normal water. Though she doesn't like having it poured on her as she stated that it smells.
