"*Life Forms have an obligation from birth to survive and procreate. Machines only live for the orders given to them by humans.*
*Life forms need food and shelter to survive. They seek the company of others, and possess sexual desire for procreation.*

*Human desires are more complicated than those of the average life form: they pursue pleasure, achievement, knowledge, among others. It is said that these desires have led man to progress.*

*A machine's raison d'etre is fundamentally different from that of a life form's. They do not feel nor express desire.*"—**"The Difference Between Machines and Life Forms" by Dr. Jayuu**, *Core Awaken ~Rusu~*

**Dr. Jayuu** *(ジャユウ博士, Jayuu hakase)* is a prominent figure consistently mentioned in the Core Awaken universe. She has never personally appeared in any of the games, but her likeness is used as an avatar by the Sin Core supercomputer.

## History

A leading authority in the field of robotics technology, Dr. Jayuu was the head of a major government program for developing a new type of android with features and mannerisms that closely resemble a human's. It began in the Urat Republic's 1002nd year, and was called the *"Rusu Project"*.

Rusu was also the name of the prototype for this undertaking, created by Dr. Jayuu herself. Though the android's physical build was a holistic reproduction of a human girl's body, her expressions and speech were cold and lifeless, no different from that of a generic robot.

The project supervisors deemed the undertaking close to completion from the prototype's external features alone, but Dr. Jayuu was not satisfied. She then developed a emotional simulation core which she christened the *"Strong Desire Circuit"* since she staunchly believed that the only way for robots to achieve humanity is by imparting to them the concept of wants, wishes, and desires. Rusu however, did not react favorably to the core. Instead of exhibiting the intended function, her ability to comprehend and respond to even the most basic commands was terribly stunted, becoming uncontrollable in the process.

Undaunted by this minor setback, Dr. Jayuu wanted more time to make adjustments to the Strong Desire Circuit but the supervisors refused, even going as far as blacklisting the core entirely since it goes against the prime tenet of robotics upheld by the capital. They also removed Dr. Jayuu from the project due to her persistence in incorporating desires to the android despite the prohibition order and replaced her with Dr. Wellie, the latter hailed as a wunderkind in the same field. Having fallen from grace, Dr. Jayuu began making adjustments to the Strong Desire Circuit on an independent basis, relying exclusively on computer simulations since Rusu was now under Dr. Wellie's supervision as the new project lead. After all, the android was technically considered government property despite being her brainchild.

While going through her simulation data, Dr. Jayuu discovered an unexpected phenomenon within the system called Core Awakening. Though it was a major step to her goal, the recorded results alone were grossly insufficient as they were hinged on too many random factors. Desperate for solid data, she formulates a plan to kidnap Rusu, reinstall the Strong Desire Circuit and subject the latter to an extreme form of field testing.

Dr. Jayuu's personal supercomputer facilitated this in the scientist's stead, detaining Rusu inside a labyrinth with the exact parameters required. The android gradually awakened to her own desires during the course of the experiment, achieving the desired results this time. With the data in hand, Dr. Jayuu developed a new type of A.I. Core that would later be applied to the next-generation smart robot line created by Ma Jing Ling, an engineer from the island of Rotai. Both technologies soon found their way to assembly lines and became commonplace not only in Urat, but other territories as well.

Nobody realized until it was too late however, that the new core had a black box containing an improved build of the Strong Desire Circuit. Aside from facilitating Core Awakening on a grand scale, Dr. Jayuu's purpose for doing so remains shrouded in mystery. For her part, the Sin Core mentioned a handful of interesting possibilities for it on her owner's behalf: among them a robot-led movement freeing themselves from subservience, a country inhabited by only robots, or key government positions held by robots.

Dr. Jayuu's exact whereabouts are currently unknown and it is unclear when she disappeared. One thing is certain though: Her legacy brought about a new page in Urat's history, a violent robotic uprising known as the Core Rebellion Incident.
