Reincarnation. It's a nice thing. You get to live your next life with or without your past life memories. In some cases you get strong and other cases weak. Some may have a good next life and some may have a bad next life. In my case, I got reincarnated into a dangerous fictional world with my past life memories. (I do not own anything I use in this story. WARNING: Grammar, slow update, and spoilers if you don't read the manga!)

Akai Suisei was one of the first people Muzan changed. The young boy wanted to grow strong and proud like his father. A chance encounter with the demon king changed everything.
