Seryu

Seryu Ubiquitous is a member of the Jaegers, formerly a member of the Imperial Police. She is a young girl with a strong (and twisted) sense of justice. She is the owner of the Teigu, "Hekatonkheires".

Although Seryu initially appeared as a kind and compassionate person, she is actually a ruthless, psychotic, sadistic and unstable person who seems to enjoy killing to a high extent those of whom she considered to be evil, almost as if it is 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 is 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 that of Tatsumi and Chelsea's, 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: seeing the authority of the immensely-corrupt Empire as absolutely right, and its enemies as pure evil. She is fully committed to her duties and relished fighting for the imperials. Her twisted view of justice 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 captured prisoners before her team could interrogate them.

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

She is also willing to go behind the back of her captain to satiate her bloodlust.

Seryu is also shown to be hypocritical. On her first mission in the Jaegers, she said that justice always fights fair and square, along with attacking head-on, but in her fight against Night Raid, she used rather underhanded means to try and win. Using a hidden gun in her mouth, she paralyzed Sheele so Koro could kill her. She also tried to kill Tatsumi and Mine from afar using her long-range weapons with no warning, basically performing a sneak attack to kill them, which would have worked has Mine not caught the scent of gunpowder.

Seryu is ultimately convinced that 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 her sense of righteousness is completely warped. As noted by Mine, she is completely ignorant of the fact that Ogre and Stylish were themselves evil, the former having framed many people for crimes and has them hanged, while the latter used humans for experiments without any moral reserve. She also has a nasty habit of showing her trademark "crazy face" every time she engages an enemy.

However, Seryu also seemed to have some limits, respecting her credibility on the Empire's benevolence, despite being in the same field. She seemed to despise Bolic due to his mistreatment of Path of Peace's female members and for being arrogant. When she presented herself in a calm way, Seryu is eager to help out people in need. She is often seen idolizing her superiors and showing deep sorrow upon hearing the news of their deaths. Seryu is also noted to at least take into consideration the lives of civilians during her battles, as shown where prior to engaging Mine and Tatsumi, she made sure to check the surrounding area for the presence of any other humans to insure no one got killed due to crossfire. Overall, taking into account her simplistic view of the world, hero-worship, and sometimes childish behavior, Seryu has quite an immature personality with a streak of emotional instability.

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

Seryu is 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 is shortened to shoulder-length after becoming a member of the Jaegers. She is typically seen in a military uniform in favor of dresses and casual wear, and is 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 not in her military uniform, she is typically seen wearing a green coat or dress, sometimes with a white skirt underneath.

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

Seryu is shown to be an incredibly gifted and talented fighter with immense potential. Seryu herself is shown to be a quick study and a fast learner when it came to acquiring new techniques or adapting to the physical modifications done to her body by Dr. Stylish, as seen where she is able to easily master the ability to completely erase her presence completely in only a matter of days by simply focusing on her desire to locate and kill Night Raid members and later is noted by Dr. Stylish to have quickly adapted to the immense physical changes done to her body and master her new equipment within a short amount of time.

Teigu

Seryu possessed a biological Teigu called Hekatonkheires which she named Koro. It is capable of growing to incredible monstrous version of itself on command, and extending its mouth open to reveal many rows of razor-sharp fangs. It also seemed to be extremely durable due to its great regeneration abilities, being able to regenerate even after being blasted with Pumpkin's enhanced firepower. It could also grow out its arms into massive proportions to annihilate its enemies. Koro's trump card, titled Berserker, greatly enhances its physical abilities and could stun opponents by roaring, although it apparently overheated after using this skill. Marksmanship & Body Modifications

Seryu is is skilled in marksmanship, proficient in a wide array of long-range artillery combat, most prominently the Judgement of the Ten Heavenly Kings with the gun installed in her mouth she accurately shot Sheele from a considerably far distance. During her battles, she is shown to have a pair of tonfas that have been modified to shoot bullets.

As a result of wanting to become stronger faster, Seryu is sent to and experimented on by Dr. Stylish, where initially she could shoot bullets from her mouth via hidden gun as a result of one of the many body modifications she has undergone. Furthermore, when her arms were severed, two guns were revealed to have been placed within her upper limbs for combat use. These were removed by Sheele during their battle and later repaired by Dr. Stylish. Where after being given artificial mechanical arms after their repair, she is able to detach them at will to use the guns freely. Physical Abilities

Seryu is shown to have considerable skill in martial arts, as she is trained by Ogre in this aspect, being able to take out Mine fairly quickly with quick strikes. Her martial arts training made her physically strong enough to create a crater on a street with a kick as shown when she ambushes Mine and Sheele. Seryu has an exceptional pain tolerance, being able to withstand all of Stylish's extremely painful body modification experiments, having her forearms severed, she quickly shrugs off the extreme pain to reveal the guns hidden in her arms and a direct shot to the abdominal area. Ultimately she could survive being bifurcated by Pumpkin's trump card long enough to activate Chakravartin Furnace of Five Hells. Judgement of the Ten Heavenly Kings

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 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: Sung Dynasty Blade - A large sword with a giant blade attached directly to Seryu's arm.
• Number 4: Unnamed Hook-shot
• 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.

• 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.

Alternative Techniques

• Justice Execution: She detaches her mechanical arms to reveal a gun within each of them. Alternatively, she shoots a bullet from the gun installed in her mouth.
• Justice Volley Fire: She bombards her enemies with numbers 2, 7 and 8 of her Judgement of the Ten Heavenly Kings.
