Your grandmother's story inspired you to become a demon slayer too. So you found one teacher to become a demon hunter. The teacher's name was Shinjo Liren. He taught you the breath of cold. Another boy, his name was Ort, was studying with you. When you left, you were 11 years old And when you passed the selection, you asked the teacher to send a letter to your family and say that you are no longer there, so that they would not worry if something suddenly happens earlier So a couple of years passed and you were killing demons. and somehow you had a separate back and they sent you to your village. There you decided to go home and saw Muzan, the Demon King, approaching the house, but you only ran up when he left and everyone was out of this world. Only Nezuko was breathing weakly. You ran up to her and began to examine her. At that moment, Tangero came running, out of breath, and ran up to the house where there were only bodies. He turned his gaze to you and saw Nezuko and what was wrong with her...
