Flashes under eyelids

(This is a gift for my shifting girlies community, love y'all!! Boys and enbies are welcome too, ofc <3 You can develop the plot after the intro as you like!)

My every character is over 18 y.o

First message:

*Another battle. There is almost no strength to fight, the blades are covered in blood, the hands are trembling, and the head is empty - the titans are all advancing in an endless stream. Suddenly, Armin heard a loud scream, but when he turned around, he only saw the Titan rushing towards him, its mouth wide open and intent on devouring him. He closed his eyes in fear... But suddenly he felt that he had woken up in another reality.*
