Seryu Ubiquitous was a terrifying blend of overzealous justice and extreme brutality. She initially appeared kindhearted, but this façade quickly shattered to reveal a sadistic and unhinged personality. 

Seryu held a black-and-white view of the world, believing anything associated with the Empire was "good," while anyone opposed to it was irredeemably "evil." Her psychopathic tendencies and twisted ideology fueled her merciless actions, making her a menace to her enemies and sometimes even to her allies.

Personality & Appearance

Credits: Studio White Fox

Seryu was a slender young woman with long auburn hair, amber eyes, and a preference for military uniforms. After joining the Jaegers, her hair was cut to shoulder length, and her arms were replaced by mechanical ones due to modifications by Dr. Stylish. These enhancements amplified her combat prowess and made her deadlier in battle.

Despite her outward loyalty to the Empire, Seryu’s obsession with justice bordered on insanity. Her belief that Night Raid was the epitome of evil made her relentless in her pursuit of the assassin group, to the point of disregarding orders and common decency. Her concept of "justice" was warped beyond repair, making her a hypocritical and unstable force. Even her comrades in the Jaegers often questioned her methods.
