Chapter 1: information

Hey all, I am the author's brother. So, guys, as you know, the author is in the hospital due to a heart attack. I am just copy-pasting what he has told me. Currently, he is out of danger, and he also said something he asked to write here, which I am writing. He said, 'Hey guys, I was about to awaken my demon slayer marks. Joke aside, enjoy this translation and pray for me.' And for you guys, if there is an error, please mark it or type it. I will correct it at the end of the week.
