Seryu Ubiquitous (セリュー・ユビキタス Seryū Yubikitas) was a member of the Jaegers, formerly of the Imperial Police. 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. 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.
