Seryu Ubiquitous

Seryu Ubiquitous was a member of the Jaegers, formerly of the Imperial Guard. She was a young girl with a strong (and twisted) sense of justice. She was the owner of the Teigu, "Hekatonkheires" until her death which also resulted in the destruction of the Teigu.

Appearance
Seryu was a young woman with auburn hair and amber eyes. During her first appearance, she wore her hair in a long ponytail that almost reached the ground, but it was shortened to shoulder-length after becoming a Jaeger. She was typically seen in a military uniform in favor of dresses and casual wear, and was frequently attired in upper-body armor. Her arms are metallic in place of flesh due to the heavy body modifications performed upon her by Dr. Stylish.

When in battle and speaking about justice, her face can distort into a warped and demented version of itself, which has become her trademark over time.

Personality
Although she initially appeared as a kind and compassionate person, Seryu is ruthless, psychotic and unstable. She was seen to enjoy killing to a high extent those of whom she considered to be evil, almost as if it was a hobby.

She has a strong fixation upon "Justice", originating from her father's service in the Imperial Army and subsequent death. She also highly respected Ogre the Demon, her superior and teacher, and was heavily anguished by his death as well. Her opinion of justice is blunt, as she believes Night Raid is evil for their actions as assassins, but believes killing in service to justice is always right, which ultimately makes her opinion of murder similar to theirs, if not completely the same.

Seryu has a twisted sense of right and wrong, bordering on a completely black and white view of the world. All the people who serve the Empire, despite the deeds they do both publicly and discretely, are considered good by her, while those who oppose it, even those who are forced against their will, are pure evil. Her twisted view of justice has caused a level of distrust towards her by her own teammates, as well as the entire imperial forces on occasion, as she brutally murdered a group of prisoners before they could interrogate the group.

This sense of right and wrong is so twisted as she lacks mercy of any kind. She has stated that evil deserves no mercy, which is ironic as that is the one thing that separates justice from vengeance or even common murder.

She is also willing to go behind the back of her Captain, despite her show of loyalty and respect to Esdeath to satiate her blood lust and was planning on killing Tatsumi as well as Mine and simply intended to say that she couldn't help herself despite knowing quite well that this would be going against orders, as Esdeath wanted them captured alive, not dead.

If nothing else, Seryu is ultimately convinced she is doing the right thing in what she does but her actions tend to be far more brutal and insidious than those of the people she believes to be evil. As noted by Mine, she is ignorant to the fact that Ogre and Stylish were themselves evil, the former having framed many people for crimes and had them hanged, while the latter used humans for experiments without moral reserve. She also has a nasty habit of showing her trademark "crazy face" every time she engages an enemy. After mocking Mine about her two comrades who were devoured by her Teigu and proceeding to say she'd have it devour her as well, Mine ultimately stated that Seryu is nothing but insane.

She has stated a dislike for dressing up during parties or the like, which coincides with her somewhat tomboyish personality.

History
She was willing to go as far as to allow Dr. Stylish to implant weapons into her body in order to better punish those she considers evil. Her mentor and superior, Captain Ogre, and her father were part of the Imperial Guard and both met their ends at hands of revolutionaries, causing Seryu&apos;s extreme thirst for punishing evil. She is often seen with her pet dog "Koro", which is actually a Biological Teigu. She briefly meets Tatsumi, and is unaware of the fact that he is a member of Night Raid. Later, she encounters Sheele and Mine and a confrontation occurs. After having her arms cut off by Sheele, she reveals that guns have been implanted into each of them, and proceeds to shoot Sheele, wounding her fatally. As a result, both Mine and Tatsumi have an intense desire to kill Seryu.

When Tatsumi is abducted by Esdeath and brought to the Jaegers&apos; HQ, Seryu recognizes him from earlier, and attempts to touch him. Tatsumi feels intense rage toward Seryu for the death of Sheele, and does not want to be friendly with her, but puts on an act in order to conceal his true identity. Later, when the Jaegers are ordered to clear out a group of bandits, Seryu unveils more of her weaponry, killing dozens of bandits with the help of Koro.

After the death of Dr. Stylish, a depressed and grieving Seryu is comforted by Esdeath, showing a rare level of compassion from the ruthless sadist.

During the mission to pursue Night Raid she is placed in a three man team with Esdeath and lured away by a ploy of Najenda, ultimately parting her from her comrades and allowing Night Raid to kill Bols and nearly kill Kurome. She had Koro devour the body, minus the head, of the only Night Raid member to fall after the incident, Chelsea.

Following their orders from the Minister and also their lead on Night Raid, the Jaegers then come to the capital of the Path of Peace. Meeting with their charge, Bolic, she voices that Night Raid, as Teigu users, can only be defeated by other Teigu users and is against the idea of letting the Four Rakshasa Demons confront them. Later on she is seen playing with a group of children on Esdeath's advice to relax on her time off.

When three of the Rakshasa Demons fall and the lone survivor, Suzuka, became more closely grouped to the Jaegers as a result, Seryu and Suzuka spot what the latter believes to be enemies, these turn out to be Mine and Tatsumi. Seryu attacks the duo with a volley, however they survive thanks to Mine smelling the scent of her gunpowder. Tatsumi then goes after Suzuka to eliminate the final Rakshasa Demon while Seryu herself confronts Mine. Taking advantage of her dangerous situation Mine uses Pumpkin's power to nearly destroy Seryu's Teigu. Seryu then has Koro enter his berserker state, as he did during the previous fight with Mine and Sheele. However, due to her knowledge of its powers gained in their previous fight, Mine proves much more formidable against Koro's abilities. Pressed by Seryu's upgraded body and weapons, Mine finally uses her Pumpkin to blast both Seryu and her Teigu in half. Seryu's final act is to detonate the bomb inside of her body in a last ditch attempt to kill Mine, however, she is saved by Tatsumi's timely return.

Equipment &amp; Skills
Seryu possessed a biological teigu called "Hekatonkheires" which she named "Koro". It is capable of growing to incredible size on command, and extending it&apos;s mouth open to reveal many rows of razor sharp fangs. It also seems to be very durable, being able to regenerate even after being blasted with Mine&apos;s "Pumpkin". It can also grow out its arms into massive proportions to annihilate its enemies. Koro also has a trump card, titled "Berserker". This enhances its physical abilities and can stun opponents by roaring, although it apparently overheats after using this skill.

During her battle with Mine and Sheele, she is shown to have a pair of tonfas that have been modified to shoot bullets.

She can also shoot bullets from her mouth as a result of one of the many body modifications she has undergone. Furthermore, when her arms are cut off, 2 guns reveal themselves to have been placed within her arms for combat use. These were removed by Sheele during their battle and later repaired by Dr. Stylish. After their repair, she was able detach her arms at will to use the guns freely.

She was shown to have some martial art skills, as she was trained by Ogre in this aspect. She was also able to beat Mine with a lot of punches.

Seryu named the following techniques:
 * Execution of the just: She shoots a bullet from the gun installed in her mouth.
 * Justice volley fire: She bombard her enemies with numbers 2, 7 and 8 of her Judgement of the Ten Heavenly Kings.
 * Justice execution: She detaches her mechanical arms to reveal a gun within each of them.

Judgement of the Ten Heavenly Kings
Stored inside of her Hekatonkeires Seryu possesses the "Judgement of the Ten Heavenly Kings", ten powerful weapons which function as modifications to her body. She often swaps these weapons around in combat using Koro's main body and, as noted by Mine, they're incredibly powerful despite not being Teigu. They were created by Dr. Stylish, as such his death keeps Seryu from modifying or upgrading them, but she does know how to perform general repair and maintenance on them.


 * Number 1: Shinkou's Ball of Justice - A large flail that can take down a large number of opponents.
 * Number 2: Four missile turrets that can be used to send out a volley of missiles.
 * Number 3: A large sword with a giant blade attached directly to Seryu's arm.
 * Unnamed hookshot
 * Number 5: Enma's Spear of Justice - A large drill-like spear that is capable of mowing down a large number of opponents. It can be launched to be used as a long-range attack. It can also explode if necessary.
 * Number 6: A giant armor reinforced missile that explodes on impact.
 * Number 7: Taizan's Cannon of Justice - A long ranged anti-tank rifle with high destructive power.
 * Number 8: An arm with an unknown ability. It was used during her justice volley fire.
 * Number 9: Justice City Detector - An arm with a radar that detects living beings in a certain area.
 * Final number: Chakravartin Furnace of Five Hells -   A last resort in the event of her defeat she has an explosive device implanted in her head. The explosion triggered by this suicide attack was easily enough to fill the small valley in which she and Mine had fought their final battle. The destructive power it possesses was proportionately intense, laying waste to the surrounding environment.
