➤ Active & Passive ESP
There are two kind of ESP. One is active ESP. The other is passive ESP. Active ESP is just that. They are active ESP users. Active users are able to manipulate their powers at will.
Whereas passive ESP cannot control their powers. Instead, their powers exist in a form of aura and is constantly being radiated.
A good example of a passive ESP is Roon Dietrich whose passive ESP is her voice. Her voice has a soothing effect. She does not control her passive ESP. It's simply there until the end of her life.
Active ESPs are more common than passive ESPs. However, it must be noted that passive ESPs are often hard to distinguish because they are often not aware that they are indeed passive ESPs. Most of passive ESPs live normal lives and never realize that they are ESPs.
➤ ESP Specialty
Higher tier ESPs, such as class S & A, often specialized in something, an element or sometimes something very unique and awkward.
Specialization of class S ESPs were quite often unique. Marat was a class S ESP with a unique specialization called "Clarity". Lila (Lilicious)'s specialization was " transmutation". Cecil Klisis' specializations were "time" and "space" and "blood".
In class A ESP's cases, specializations were often cosmetic elements: fire, water, earth, wind, lightning, and so on.
➤ ESP class S
Extremely rare cases of ESP. The most class S ESPs ever existed was between 85xx to 97xx. However, the number never exceeded ten at once. However, it must be noted that not every ESP was able to go through proper testing examinations. Therefore, it was feasible that there might have been more who were not registered.
More likely, however, if one was a class S ESP, people around him/her would notice sooner or later.
Class S was determined when one's ESP powers were well ESP beyond score charts. In some cases, class S ESPs were treated as human treasure, for they were capable of seemingly impossible.
Class S ESPs had a strong tendency to possess often very awkward personalities which allowed them to act more like villains than heroes. Such examples were Cecil Klisis, Sae, Juron, Aedy Freedom, and so on.
Masu the sage, explained why it was so. He once said, "Class S ESPs can often foresee into the future. It is not their power however. They are able to predict because they are too smart. When you know too much about how something will end exactly, you can't act like a hero."
➤ ESP class A
A much more common class ESPs that were found in Two Clusters. Many great heroes were class A ESPs. Shell of Pluto was a class A ESP. Gair was a class A ESP.
Like class S ESPs, class A ESPs often possessed specialty. The most common specialties were cosmetic elementals (Fire, Water, Earth, and Wind).
➤ ESP class B
Weaker than class A but stronger than class C. Class B ESPs are the workhorse of elite forces. They are very often hired by government agencies to become either agents or elite soldiers. Some of them have a specialization which enables them to reach prowess of class A ESP in their specialization.
➤ ESP class C
No class C ESP has a specialization. They are very weak ESPs. Unlike class B ESPs, they don't always get hired by government agencies. When they do get hired, they are usually stuck with basic tasks. Most of class C (and D) ESPs lead normal lives.
➤ ESP class D
Class D ESP is the most common ESP and the most useless ESP at the same time. What a class D ESP is capable is very little. They might be able to see through a deck of cards. That is pretty much it. Some of them work in entertainment industry as magicians.
Overexerting for ESPs have dire consequences. But in return, it'd grant an ESP ten times more powers than they normally would.
When an ESP overexerts, the first symptom is bleeding from nose, ears, and eyes (bloody tears). A short while later, face would become bruised. (This symptom does not happen to all ESP who overexerts.)
An overexerted ESP, at this point, would normally become unconscious. This is the crossroad for ESPs. Some will die. Some will survive.
➤ ESP age
An ESP (Class C+) can easily live well past 600 years old, provided that they don't get killed in action during their lifespan.
The average lifespan for ESPs is 800 years old. A few live past 1,000 years old. Masu was one of the oldest ESP ever in the history of Two Clusters, who died at 1,092 years old.
