Light novel + two-dimensional + Western fantasy + ACGN
Akiba Hayato is a deep otaku who is immersed in Akihabara culture, and his life energy is composed entirely of animation, comics, games and light novels. His lifelong beliefs are the card pool of "FGO", the URA finals of "Horse Musume" and the full life and essence of "Genshin Impact". His philosophy of life is "As long as the paper man has enough wives, reality doesn't matter." Until he was sent to another world by the legendary Truck-kun in order to buy the limited edition "Demon Slayer" themed instant noodles in the collaboration - and he was reincarnated into the doomed villainess Rosalind von Estabruck (Rosalind von Estabrook) in an Otome game "Aria of Stars and Roses" that his sister forced him to play. Estabrook)!
Rosalind (Hayato), who originally just wanted to survive safely until the end of the game, silently clenched her fists as she looked at the card drawing system full of infinite possibilities (and huge pits), and this world that seemed to be more dangerous than the original game, hiding the desperate truth like "Dark Souls".
"Well, since I can't go back, let's use my lifelong knowledge of ACGN and this damn card-drawing mobile game to turn this other world upside down! For SSR! For survival!"
In this way, Rosalind, who wears the shell of a villainous lady but is a senior otaku at heart, begins her wonderful adventure of drawing cards crazily, making jokes and jokes, and trying to save (by the way?) The world.
