Recurrent Spontaneous PsychoKinesis Syndrome (RSPK Syndrome) (反復性偶発性念力症候群 (RSPK症候群) Hanpukusei Guuhatsusei Nenriki Shoukougun (RSPK Shoukougun) ?) is a term used to refer a condition that affects the espers of Academy City, wherein an esper loses control over themselves, causing a subconscious and uncontrollable outburst of power. The manifestation of this phenomena varies by esper at an idividual level.
Interference on the AIM diffusion fields of espers can also cause simultaneous outbreaks of RSPK Syndrome to occur. Also when multiple overloaded espers (as with the case with Kiyama Harumi's students) with the same AIM diffusion fields are gathered together, their powers resonate and causes an occurrence of RSPK Syndrome.
Apart from the abnormal occurence of moving objects (like teacups and dolls) and other similar unnatural events, a poltergeist can also cause earthquakes. Poltergeist earthquakes occurs when the abilities of multiple out of control espers converge on a large scale, from a human sensory perspective they are perceived as earthquakes. A large enough occurence of poltergeist earthquakes can cause significant damage, and can seriously injure bystanders. In the worst case scenario, a city like Academy City could have 78% of its population be affected by a large enough occurence of RSPK Syndrome.
Toaru Kagaku no RailgunEdit
Due to Kiyama Harumi's attempts at reviving her comatose students and Haruue Erii constant attempts to telepatheically contact one of them, Edasaki Banri, sporadic occurences of RSPK Syndrome are happening all around Academy City, causing various amounts of damage. Because of these events, Judgment, Anti-Skill and Multi Active Rescue have formed a meeting on information about the recent earthquakes. With the help of Misaka Mikoto, Therestina Kihara Lifeline, the head of Multi Active Rescue were able to find Harumi and obtain custody of the children.
It is eventually revealed that Therestina is also the granddaughter of Kihara Gensei, the researcher who performed an experiment on analysing the overloading of esper abilities on Harumi's students, and plans to continue his experiment on achieving SYSTEM or level 6, by using Harumi's students as well as Erii. This wll cause an overload of their abilities, theoretically achieving SYSTEM, however it can cause the destruction of Academy City.
