Theater of Samsara of All Realms

I died once. I pushed a stroller away, was hit by a truck, and woke up in an amphitheater with only stone doors and stars. A door opened and I stepped into the Mugen Train of Demon Slayer: Kimetsu no Yaiba. That night, I committed suicide seventeen times in my dream. This is the reincarnation game I was chosen to participate in - surviving in every familiar anime world. Every time you live in a world, you are entitled to three days to return to reality and take a breather. When three days are up, the next door will open on time, whether you like it or not. I can survive until now because of a special rule: by establishing a bond with the plot characters, you can gain their abilities. The deeper the bond, the stronger the power. But these bonds also made me the most valuable prey in the eyes of the indescribable being deep in the theater. In the real world, someone is waiting for me to go back. The girl upstairs who taught children to draw and always had paint on her nose gave me a painting and said it was a "receipt" - I owed her something and I had to come back alive to pay it back. My mother back home is still waiting for the news that I am getting a wife. In front of the tombstone of the old squad leader, I still owe half a bottle of unfinished wine. So whether the next world is hell or heaven, I will walk through that door. Come back alive. This is the most extravagant wish of every reincarnation. And I must turn it into reality.
