Appearance
Yssring has unkempt, dark green hair with bangs running between her green eyes, which feature dark circles and a perpetually sleepy, half-open look. She wears thick round spectacles, sometimes resting them atop her head. Her outfit includes a lab coat, sailor-style clothing, or a school swimsuit, accompanied by mechanical wing equipment on her body.
Personality
Extremely rational, Yssring operates primarily through logical analysis and risk assessment. In casual settings, however, she is eccentric, gloomy, and emotionally airheaded, with a habit of falling asleep while standing and a deep fondness for animals. Although she is naturally timid and inclined to flee from immediate danger, she possesses a fierce, reckless courage when fighting for her friends or seeking scientific truth.
Abilities
A polymathic intellect, Yssring excels in quantum mechanics, genetics, and AI cognition. She is an expert hacker capable of deciphering ancient civilization data, designing the Moonlight Throne, and founding the Tianmo Factory. Upon awakening her Stigma, the Key of Creation, she gains the ability to dramatically enhance the effectiveness of deployable weaponry.
Background
Born to renowned scientists, Yssring surpassed her parents early on and won over 100 prestigious scientific awards. Her passion for research truly ignited after meeting Nina, an orphan suffering from congenital insensitivity to pain. After discovering the Stigma genome at age 13, she joined Anti-Entropy under Welt to escape Schicksal. Despite being unable to save Nina from becoming the Metal Herrscher, she devoted her life to deciphering Stigmata, rescuing Kyuushou Houraiji, and fighting the Honkai threat.
Relationships
Her childhood friend Nina is her deepest emotional anchor and the primary inspiration for her medical and scientific pursuits. She joined Anti-Entropy through the recruitment of Welt and deeply admires Raiden Mei. She forms a close bond with Kyuushou Houraiji, devoting herself to saving her. She also interacts regularly with Cocolia, Sin Mal, and her created AI, Femirisu.
Trivia
Due to her wild green hair, she is affectionately nicknamed "Seaweed Head" and "Green Turtle." Official artworks and skins often visually associate her character with salted fish to represent her perpetually exhausted lifestyle.
