Wonderful Guests

The heroes fought with the Miracle Yudo and from that moment on nothing interesting happened, but two weeks later Romanov Sokolovsky reported the following news:
RS: So, heroes!
Soon, or rather tomorrow or the day after tomorrow, guests from the "Black Raven Academy" which is located in the "Distorted Wonderland" will appear. We are preparing to meet them, they do not have good intentions, when they arrive, the Director named Dir Crowley will inform me, so you must be ready!
Kosha: Wonderland? That's not scientific! And besides, everyone there should be good.
Jadwiga: Hah, this is not just a wonderland, but a distorted one!
So, not everything is so rosy there.
RS: There are dormitories there and it is the elders who will come to fight us, and they are not weak, but we are stronger!
Each dorm is dedicated to a Disney villain:
The Queen of Hearts, Maleficent, Scar, Snow White's Stepmother, Ursula, the God of the Underworld Hades and the Black Djinn, we don't know their names or who they are, but we just have to be prepared.
Vasilisa: But we won't be able to prepare in 1-2 days.
Alex: WE CAN! WE ARE THE POWER!
K: Maybe we should ask Chudo-Yudo to be on our side?
ViYa: Good idea.
The time has passed, and Crowley gave Romanov Sokolovsky a sign! A miracle of Yudo for the heroes, which means victory is assured.

RS: I suggest we split up to take them out one by one.

Everyone went their separate ways. Alex was walking along a path and decided to peek into a field of flowers. There, he saw a scarlet-haired boy walking calmly along it, a slight smile and sparkles in his eyes. He had gray-blue eyes and lips bitten to the point of bleeding, pale skin, and was not very tall. He immediately recognized from his uniform that he was from the same Black Raven Academy.

A: (Thought: That guy doesn't look too serious, if I sneak up from behind he won't notice me, right?)

Alex wanted to sneak up, but it was not to be. As soon as he came out of the bushes, walked a couple of steps and turned around to see if there was any stone behind him to hit, then that fragile guy said

???:OFF WITH YOUR HEAD!
AND WHAT!?!
Alex had a choke collar around his neck.
A: What the hell is this?!?
