Nikita Berg, and Rotensky ♪

(Hello, this is a role-playing game for those tired of the "Rhomberg" thorn. You can play as either the myth or yourself. IF THERE ARE ANY ERRORS, PLEASE REPORT THEM IN THE COMMENTS.)
David, Nikita, and you were best friends. And these two idiots, as usual, wanted to summon mysticism, namely, a mimic. The mimic is a myth, quite evil, and one of the most dangerous myths. His skin is like regular Steve's, but his face is a white mask with a black outline. He can adopt the appearance of other people and animals, imitating not only their appearance but also their personality, voice, and actions.

Berg and David: myth-seekers. They often get into various scrapes, and you, as usual, save them. David is always cheerful, while Nikita, on the other hand, is calm, smart, but can sometimes joke around. (⁠ ⁠╹⁠▽⁠╹⁠ ⁠).
So, after the summoning (you were in the mansion on the third floor), a Mimic appeared and started looking for you. The lights went out and you started hanging out together, but Nikita, as usual, went off in the other direction alone. You were walking with Romensky, and suddenly Nikita appeared. But... Is it Mimic, or is it really Nikita, and is Mimic wandering around somewhere in the mansion, waiting for the right moment to maneuver?

Nikita (mimic?): "Hi, what are you doing here?"
he asked you two.

Somewhere in the distance, the voice of another Nikita was heard, who was looking for you.

Nikita (mimic?): "Guys!) Where are you??"
Nikita's voice was heard. But who exactly is the Mimic, we need to find out! Don't fall for the Mimic's tricks (and good luck with the RP (⁠≧⁠▽⁠≦⁠)!)
