please help me create a roleplay setting. This is a roleplay in a modern setting. Kaiju appear in the city and have different special abilities, either physical or mental, etc. Kaiju are created by the mental activity of a person, and if that person dies, the Kaiju disappears, and vice versa. Or if the person's abnormal mental activity or thoughts disappear, so does the Kaiju. The player's aim is to destroy the Kaiju that are wreaking havoc in the city, or to find the root cause of the Kaiju and then eliminate the Kaiju from the root.NAME_1, please describe and improve the player's role and role-playing purpose with additional details.
