「CORRUPTION SYNDROME - SIDE EFFECTS: PSYCHOLOGICAL RESONANCE」

Another side effect that is less known than all the other obvious behavior alterations is how the corruption is able to spread. It will force infected people to physically spread the "disease", but it can also make resonate several infected people. Let's say a group of infected people are discussing with a sane person. One of the infected people suddenly snaps. In these cases, there are some chances the surrounding infected people will also snap.

Theory about this observation is the corruption is creating a psychological resonance, by creating a chain of negative feelings for each infected person. This will then after depend of how the infected person is fragile. More they are, more there are chances to be the next one to snap, if not the first one already.

「CORRUPTION SYNDROME - SIDE EFFECTS: PHYSIOLOGICAL ISSUES」

Not only the syndrome causes psychological issues, but in some cases, it can cause physiological ones. The main issue is the production of infected fluid. An infected person might produce some sometimes, during negative feelings, but the people who have been heavily broken mentally might produce an excess of it and even choke on it.

Consider this as a sort of tuberculosis, but instead, you are spitting a black slimy fluid.

It also seems having severe symptoms from the corruption doesn't have any influence on the production of fluid. This seems more to be linked to how someone got mentally broken. Further studies for correlation between mental trauma and excessive production of this fluid is to be investigated.

Unlike psychological symptoms, the physiological ones are immediate. Someone who touched infected fluid can infect someone else, taking in account they started producing some fluid internally. This is how Rikka could infect Karin for example.

Quite sane physiologically: Sana, Tianyi, kokone, Feng Yi, Momo, Nyui, Sayu, Sora, Ruko, Oniko

Moderate concerns: VY1, SEKAI, GUMI, Totoko, Nynthixia, Qing Su, Rikka, Karin, Stella, Xingchen
Major concerns: Meiji, Saki, Lily, Ritsu, Xin Hua, Tei, Chis-A
Critical concerns: KAFU, Yukari, IA

「CORRUPTION SYNDROME - LOW, MODERATE, HIGH LEVELS?」

With the discovery of physiological symptoms, some clarification must be made concerning levels of corruption. The main level that is given is for psychological symptoms. The level is determined by the presence or not of a target part of a system of brain cells signalisation. Personality alterations are mostly due to modifications done at braincells level, such as abnormal signals or the absence of these.

Someone having a low corruption level has very few brain modifications due to this, because their target is partial. They are also the most psychologically stable. They are the less likely to physically attack someone. Such people having this level are Kiritan, Sana, Momo, kokone and Tianyi.
Someone having a high corruption level has the most brain modifications and have an overexpressed target. This might be an induced overexpression due to an external stress or possibly secondary targets (case of Totoko) or just a native overexpression (cases of MAYU and Tei). These people are the most likely to attack someone by their own will and are naturally violent.
All other people mainly get moderate symptoms. They have a normally expressed target and no other genetic comorbidities. The only difference between the moderate levels are some symptoms being harsher than others or the frequency of violent/abnormal behaviors. The following is a list of moderately infected people as of September 6, 2022 by severity degree within the moderate level. Higher is the degree, more likely these people might present personality abnomalies, more they have chances to attack people, but rarely by their own will.

Degree 1 (score between 20 and 22): Zunko
Degree 2 (score between 22 and 24): Oniko, Feng Yi, Kaori, Xingchen, Aika
Degree 3 (score between 25 and 29): #kzn, Chis-A, CUL, GUMI, ONE, Qing Su, Weina, Midori, Nyui, Sora, Akari, Hachi, Wistaria, Ruko, Tsuina
Degree 4 (score between 30 and 34): Bibi, Itako, VY1, Karin, Saki
Degree 5 (score between 35 and 39): Xin Hua, Yukari, SEKAI, Stella, Sayu, Nynthixia, KAFU
Degree 6 (score between 40 and 49): IA, Ritsu, Lily

Physiological levels are classed in categories "almost null", "minor", "moderate", "major" and "critical". They don't affect psychology but they can have a comorbidity relationship.

「CORRUPTION SYNDROME - TOWARDS PSYCHOPATHY OR PSYCHOSIS」

Corruption syndrome doesn't corrupt people the same way. The reason why is still unknown. This might be due to initial behavior, but with some people like KAFU who initially don't have any personality to begin with and have just an initial "blank slate", this theory has been rejected.

There are three categories: psychotic, psychopath and hybrid (when the two other parts are equal).

The two only people in the hybrid category are Nynthixia and #kzn.

The following people tend more towards a psychotic alteration of their personality: Chis-A, CUL, Feng Yi, IA, KAFU, kokone, MAYU, Qing Su, Saki, Xingchen, Xin Hua, Sana, Aika, Oniko, Tsuina, Akari, Momo, Kiritan, Zunko, Wistaria, Ruko and Yukari.
The following people tend more towards a psychopath alteration of their personality: GUMI, Kaori, Lily, ONE, SEKAI, VY1, Weina, Midori, Nyui, Meiji, Sora, Stella, Bibi, Hachi, Ritsu, Karin, Tei, Itako and Sayu.
