Kohina Hiruko

Kohina Hiruko (蛭子小比奈, ひるこ こひな, Hiruko Kohina) is an Initiator and Kagetane Hiruko's daughter. She is the secondary antagonist of Black Bullet.

Appearance


Kohina dons a small dress with many intricate designs in the middle areas, connected to a bottom skirt that covers her entire lower body. The dress's blouse displays a set of lighter color edges on either side of the loose shoulder garments. Around her neck, with lighter outlines visible as well, the blouse is gifted with a hole revealing a small portion of her chest. Further; her stomach is covered by a slightly thicker adornment that spots a display of complex artwork. On the back, Kohina dons a piece of clothing that allows her to sheath her double blades. Finally, the bottom of the dress that covers her lower regions seems to have two layers of clothing, resembling petals, and being of a light color.

Personality
Kohina, like her father, gives off a cruel psyche and will annihilate those that stand in her way without any remorse. She, however, seems to question her father when it comes to ending someone's life, demonstrated when she asks him if she could kill Rentaro Satomi, who was pointing a gun at them at that time, and later when she also repeats the same action with Enju Aihara.

She also displays a vengeful persona against those that have previously corrupted her plans or saved someone she aimed to kill. When said events happen, she loses her cool and badmouths the ones she fights, calling them weak.

Aside from her cruel psyche, she doesn't seem to be completely devoid of emotions. After Rentaro defeated Kagetane, who ended up in the water, she burst into tears, being sad upon his apparent death.[34]

History
When Kagetane was younger, he had kidnapped five women and artificially inseminated them. Along with that, he gave each embryo a large dose of the Gastrea Virus, turning them into Cursed Children. He had locked up his daughters in separate underground rooms for six years, brainwashing and teaching each one how to kill. When he finally released them, he had them all meet and try to kill each other. The one that survived was Kohina. It has been stated that Kohina possesses praying mantis Gastrea gene, and that when she is in possession of swords or blades she is invincible. Her license, along with her father's, has been revoked due to several problematic movements; they had an IP Rank of 134 when they were part of Civil Security.

Civil Security arc
Kohina, around the area where a Gastrea was located, calls her father on his phone, and is told that he will meet with her outside in a few seconds.

The Cursed Children arc
At the meeting where several Civil Security Corporations were called by Seitenshi, Kohina and Kagetane enter the room, uninvited. She passes by Rentaro quietly, unnoticed, and climbs up the table where he father is standing. She introduces herself, and informs the people in the room that she is an Initiator. She looks at Rentaro pointing his gun at them and asks Kagetane if she can cut him down, only to be told that she can do so other day. Her sword, dripping blood, shakes along with her body as she tries to bear said desire. She stands next to Kagetane as he speaks to Civil Security about the case Seitenshi just spoke about; claiming that he will get it first. Before long, they are ambushed by Shougen Ikuma and his Initiator, Kayo Senju. However, she is protected by Kagetane's Repulsion Shield. After the two leave a box in front of Rentaro and overpower the people present, they escape through the destroyed window behind them.

Kohina comes crashing down when Kagetane orders her to cut off Rentaro's right arm. However, he dodges her attack, but she regains her posture quickly and appears behind him stating that if he keeps moving she will cut off his head. Before she can continue her assaults, Enju interferes as she kicks her from above. Kohina questions her appearance, and when she receives an answer, she admits to Enju that she is model mantis Initiator and that she will remember. She points her sword at Enju, but before she can attack, Kagetane stops her as he reminds her their reason for coming. Standing next to her father as he invites Rentaro to join forces with him, Kohina is shocked when Rentaro denies. Afterwards, the two leave the area.

Legacy of the Seven Stars arc
A few days later, Kohina reappears and directly attacks Enju whilst Kagetane handles Rentaro. She uses tremendous force to cut down the trees nearby in an attempt to kill Enju; smiling devilishly. Their fight is quick to end as Rentaro interrupts them by shooting at Kohina to allow Enju time to escape. Angry, she heads towards Rentaro when Kagetane forbids her from chasing Enju, stabbing the young boy in the back with her dual swords as she calls him weak. Moving her body back to evade Rentaro's counterattack, Kohina follows Kagetane's league as he gets the case and shoots Rentaro, leaving him to die.

Shortly thereafter, inside a territory infested with high level Gastrea, Kohina and her father are spotted by various Civil Securities hiding around the area. Kohina, inside a building alongside her father, is ambushed by Shougen Ikuma and many Civil Securities surrounding the area. The two manage to kill the Civil Securities opposing them, including Shougen, whom they kill by stabbing him with his own sword. The duo is soon enough confronted once again by Rentaro and Enju. Kohina readies her blades as she looks at the angry Enju.

Kagetane questions Kohina; asking if she is prepared for the battle, to which she replies affirmatively. Just then, Kohina stands ready with her swords as Kagetane releases his Maximum Pain, granting her enough time to hide her presence within the smoke. Subsequently, she jumps out of the cloud of smoke and aims at Enju, separating her from Rentaro with a slash of her blades as Kagetane states that Kohina has been eager to fight Enju. Kohina and Enju continue their battle elsewhere, observed by an Electronic Eye floating about.

Kohina's battle with Enju is interrupted when latter turns to look at Rentaro's Varanium limbs in dismay. Quickly enough however, she flees her battle with Enju to ambush Rentaro with her blades when the Promoter assaults her father with a strong punch. Albeit, before she is able to pierce him, Enju appears in front of Rentaro and knocks Kohina back with a powerful kick. Once she regains her balance, Kohina takes note of the fast approaching Enju; getting her swords in position for attack. Howbeit, she is left with wide eyes when her opponent's real target is Kagetane. Before getting a change to go after her, Rentaro appears behind Kohina and sends a punch towards her direction. Kohina intercepts the attack, sending him backwards with the mere slash of her blades as she calls him a weakling. Much to her horror, Rentaro admits that because he is weak, he knows what tactics to use when facing strong opponents; Kohina takes note of the Flashbang hanging from one of her blades, but is unable to react in due time. Subsequently, she is attacked by the reappearing Enju who uses the distraction to her advantage, striking at her blades strong enough to shatter them and send her flying into a nearby body of water along with her father.

Moments later, she is inside her father's Repulsion Shield when they reappear to counterattack, creating a massive hole inside the water. She follows Rentaro and Enju along with her father when they begin to runaway; rapidly reaching their location. She listens to her father's words, claiming that he plan to release a Stage V Gastrea for the sole purpose of fighting, since—he claims—the existence of people like them is just that. When they cease their conversation, Kohina swiftly appears behind Enju and attacks her, sending her towards Kagetane's ready gun. Standing to the side, Kohina can only watch as Rentaro steps in front of Enju to protect her from the Varanium bullets, and as he releases a loud roar after injecting himself with an injection.

Kohina watches as the bullets shot by her father begin to fall out of Rentaro's body. Momentarily, she attempts to aid Kagetane when Rentaro overpowers him, but Enju stands in her way. Angrily Kohina orders for her to step aside, only to be rejected. Shortly enough, however, Kagetane is able to blast a hole through Rentaro's abdomen by utilizing his Endless Scream, allowing Kohina to return to his side. Quickly, she reappears behind Enju, delivering a kick that sends her flying away from her Promoter. Now standing in front of Rentaro, she watches as Kagetane mercilessly shoots Enju with Black Bullets.
