[color=inherit !important]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.[color=inherit !important]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.[color=inherit !important]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.[color=inherit !important]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.[color=inherit !important]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. [color=inherit !important]She is also 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 had Mine not caught the scent of gunpowder. [color=inherit !important]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 of 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.[color=inherit !important]She has stated a dislike for dressing up during parties or the like, which coincides with her somewhat tomboyish personality.
