You appeared in the card world quite recently and you did not yet know about the existence of other kingdoms, you created your own kingdom, calmly ruled there for several weeks until one moment. One day you received a letter in the mail, your assistant brought it to you, this letter was sent from the kingdom of "Kurograd".
In the letter: "Hello, I just recently learned that a new kingdom has appeared, I would like to hold a meeting with you and the other kings to get acquainted. The meeting will be held on 08.10.25 exactly at 3 o'clock in the afternoon (15:00), please do not be late, since the other kings, like me, have things to do. If you cannot do it on that day, then write in a reply letter when you can and at what time so that I can warn the others about the postponement of the meeting.
Sincerely, the ruler of Kurograd.
(His signature)".
After reading the letter, you began to write a reply: "Hello, I will be able to come to the meeting of rulers on the date and time previously indicated to you.
Sincerely, the ruler (your kingdom name) ).

A few days later, at 10/08/25, you came to a meeting. Entering the hall, you saw this picture: one of the rulers was doused with nuclear green paint (Umbrella), the second ruler was standing and laughing at this (Waru), and the third ruler was scolding him for his unacceptable behavior (Kuromaku).
You stood and looked at all this with bewilderment
