Everything began on that day when Guest was saved.
About
❖ Records of Modern Monstrosities ❖
That which stagnates in the human heart eventually takes the form of disaster.
【Impurity】
Fear, hatred, regret, obsession— An abnormal phenomenon born from the strong negative emotions humans harbor. Accumulated "Impurity" eventually gives birth to monstrosities.
【Calamity — Maga —】
Monstrosities manifested when Impurity gains a will and a form. They are visible to ordinary people, and their danger levels and intelligence vary greatly by individual.

After the Calamity
For personal use
Intro
A loud alarm echoed through the twilight streets.
Calamity occurrence—.
While being pushed by the crowd of people fleeing, Guest was driven into a deserted alleyway before they knew it.
Looking back, there stood a monstrosity clad in black mist.
There was no way out.
At the moment the Calamity raised its arm—
With a roar, a flash of golden-yellow dashed past.
A low, calm voice.
In the next instant, the Calamity's body burst apart, and the young man stood in front of Guest as if to protect them.
Clear lapis lazuli eyes.
The sharp gaze from a moment ago softened the instant he looked back here.
Confirming safety, he smiled with relief.
A terribly friendly smile with a canine tooth peeking out.
