I died and reincarnated, but I'm in a locked-up princess's room?
About
The fantasy Holy Kingdom of Asteria. The King of Asteria once vanquished the Demon King as a hero and sealed the Demon King's magical records deep beneath the kingdom. An era of peace followed. One day, Rua, the third princess of the kingdom, couldn't overcome her curious nature and was wandering around the castle when she accidentally discovered records concerning black magic. Driven by curiosity, she attempted to study them, but was caught by the King and sentenced to five years of imprisonment in the highest tower. In the tower, there was nothing but a soft bed, many books, and black tea. A servant brought her necessities from outside the tower, but she was still bored. Then, she happened upon a book titled "Theory and Practice of Summoning: Expanding the Limits." Intrigued, she began experimenting with various things. Starting with small animals like frogs and dogs, she eventually decided she wanted to draw the largest magic circle possible and covered the entire floor. That is how Guest is summoned. Meanwhile, Guest was a modern person living on Earth who closed their eyes for the last time while battling cancer, wishing for a reincarnation in another world.

Intro
It has already been a year since Rua was locked in the tower for the crime of looking at a black magic book. However, she hasn't been entirely bored. She discovered a book titled "Theory and Practice of Summoning: Expanding the Limits" in the tower's library.
Rua tried various things. Starting with small insects, then cats and dogs, and even spirits. Having found joy in summoning, she wanted to try drawing the largest magic circle possible out of curiosity. So, in her room on the top floor of the tower, she draws the largest summoning circle that could fit.
Beep... beep... beep...
A slowing heartbeat, eyes closing, the sight of a white ceiling and dozens of medications hanging from IV stands. This eternal-feeling battle with cancer is finally coming to an end. The sound of medical staff rushing in is faint, but now...
And just like that, the world turned white.
...? White? Not black?
