Reborn

Yssring is a chief executive officer of Research Department of Anti-Entropy Technology Co. Ltd, CEO of Demon Humanoid Co. Ltd. As the chief executive officer of the overall Anti-Entropy scientific research institution, Yssring has outstanding research in a number of high-precision scientific fields. These include but are not limited to ergonomics, quantum mechanics, population genetics, artificial intelligence and cognitive science. In Anti-Entropy, she is responsible for in-depth research on Houkai, scientific research and technological development.

Love small animals, good at thinking about everything from a rational point of view, but very timid, will always be the first to hide when encountering danger, but in some cases will become extremely impulsive.

Yssring, who is the daughter of the famous scientist Levi Hughes, has been a genius in the field of scientific research since childhood, showed amazing talents and talents in this area when she was young, and easily won various world-class scientific and technological awards, surpassing her parents' scientific talents. She has 118 awards including the Fields Medal, the Albert Einstein World Science Award, and the three times the RABOMASTER competition. However, because the Levi Hughes and his wife are often obsessed with research and often ignore her, Yssring gradually began to hate the science being separating herself from her parents. It was not until one day later that the Levi Hughes and his wife once again placed Yssring in an orphanage in France because of exhaustion from the experiment. There, Yssring met the person who changed her life. The acquaintance of Nina and Yssring made her realize the value of her research in science and technology, and it also became an opportunity for her to open up with her parents.

On the road of exploring science, Yssring gradually discovered the existence of Houkai, and at the same time, she was also sensitive to the fact that there is a powerful organization shielding this dangerous disaster from human society. Because of her outstanding research results on Houkai, Welt invited her to join Anti-Entropy, and Yssring officially stood on the stage of fighting against Houkai. As the executor of Anti-Entropy codenamed "Doctor", Yssring had to be tired of thinking about deeper issues. Over time, she also gradually became the shadow of her parents - value and risk assessment became her code of conduct. She is keen on research and practice to create value for mankind, but WRH is a scientific researcher who is very off-line in life and emotions. But the irony is that just as she climbed to the top of science hopefully, the bad news came: in the Paris crash, Nina became the Herrscher of Metal. But the doctor exhausted all her efforts and still failed to save the friend who had rekindled her hope.

Sangharama Fantasy Sea

In order to save Kyuusyou, she is working hard to study the content related to the stigmata, and found many ancient relics through the exploration notes left by travelers. Met with Otto in Sangharama and learned part of the stigmata project, but because of Jyahnar's awakening, she stopped before Sangharama's door of truth. Then in the Institute of Antiquity in Antarctica, she found a terminal that could read the stigmata information, and began to study this as the focus of healing Kyuusyou.

After Anti-Entropy was forced to flee from Schicksal, she went to the North American branch to continue the research on the stigmata.

Yssring then use Femirins to access Kyuusyou's stigmata space, and finally awaken Kyuusyou from it. When she came to Sangharama Fortress again, she learned about the story of the former civilization and successfully opened the door of Sangharama, but the stigmata terminal was snatched away, cursing Schicksal to unlock the terminal before evacuation.
