Demon slayer (tanjiro x OC fanfiction)

3: whats a train?

My guidance crow came to me as it landed on my fingers. "Hello birdy" I said. "You have another mission, in tokyo. Rumor has it there's a demon around" the bird said. "No breaks.." I thought. "Well.. the fastest way to get there is by train". I started walking towards the train station. I got there.. It took a while but I was faster than I thought. "So this is what a train is" I said. Looking at it by every angle. "Wow" I said. "Truly amazing" I continued. I got onto the train and sat down. I looked forward and noticed someone opposite me was wearing the demon slayer uniform. "Hello," I said. His head turned and I realised who it was. "You're that guy.." I said. "Oh it's you.." he replied. "I don't think I said thank you, for you saving me at the final selection" he continued. "It's nothing, there's no need to say thanks" I said. He smiled. "Are you going to the mission in Tokyo?" I said to start a conversation. "Actually, yes I am," he said. I looked next to him "a box?" I thought. It was over sized. I could sense something in it, something alive. But I hid the fact that I thought that. "So we have the same mission" I smiled. "What's your name?" I asked. "Tanjiro Kamado," he said. "You?" he asked. "Ozawa Miyako," I said. While the train went on we continued talking. I could sense the kindness that I felt him feel at the final selection. Soon I got tired and slowly drifted off to sleep.

The train stopped and Tanjiro woke me up, "Ozawa it's time to get off the train" he said. "Oh thanks for waking me up.. I didn't notice I was that tired" I said. "It's okay," he said while smiling. "That smile.." I thought. I noticed that he was carrying the oversized box everywhere. Both of us were overwhelmed by the amount of people there were at night time. "This is making me dizzy," he said. "I agree, let's find somewhere not so crowded" I said. We walked to an udon stall. "Can I please have one bowl of udon!" Tanjiro said. "One bowl of udon coming right up!" the chef said. We sat down right next to the udon stall and Tanjiro started eating. At the exact same time we both stood up. "I sense a demon" I thought. Tanjiro dropped his bowl, grabbed his box and started running towards the sense, I followed as I wasn't that far behind him. He touched the shoulder of what looked like a demon. "Muzan Kibutsuji! I know it's you!" Tanjiro said angrily while gritting his teeth. The guy Tanjiro was touching turned around. "It's definitely a demon," I thought. When he turned fully around both me and Tanjiro looked surprised. "He has a child? And a wife? They are both human.. So this is his disguise.." I thought. I was reminded of the time my father was talking about Kibutsuji, saying he was the most powerful demon and any of his blood exposed to the human body would make that human a demon.

Both me and Tanjiro saw him touch a guy that was just passing by. The guy started attacking his wife. Tanjiro instantly got his scarf and shoved it into the guy's mouth. "Stay back!" Tanjiro said. "This guy is now a demon, you need to stay away" he continued. "How sad.." I thought. I noticed that Kibutsuji started walking away. I followed him as fast as I could.. But I wasn't fast enough, "dammit he's gone!" I said. he had already disappeared into the crowd. I felt responsible for not being able to keep up with him.. I went back to Tanjiro. Oh no there were police that were not helping him at all. In fact they were trying to take Tanjiro off him. I got in front of them "Stay away from Tanjiro!" I said angrily. Then I noticed some kind of spell.. It somehow made the police go away. And I saw two people walking over to us. "They're demons.." I sensed. Both me and Tanjiro saw them. "I am Tamayo, and this is Yushiro. I am a demon however I am also a doctor. I want to do all I can to destroy Kibutsuji" one of the demons said. They both left with the guy who was transformed into a demon and his wife who was attacked.

Both me and Tanjiro went back to the udon stall. The chef was not impressed. "How could you just destroy a perfectly good bowl of udon!" he said. "I'm sorry!" Tanjiro yelled. "Give me two bowls of udon!" he continued. The chef said "okay.." "Get me a bowl of udon as well," I yelled. "Yup" the chef replied. "Thank you," I said. Both me and Tanjiro started eating. Tangjiro was hungry.. "tanjiro..I need to tell you something.." I said. "What is it?" he said while finishing his last bowl. "Kibutsuji.. He was right in the grasp of my hand.. But i lost him, i failed" i frowned. "Well I'm not the best when it comes to this situation but I saw you attack at final selection. You are not a failure" he said. "You really think so?" I said while lightly crying. He nodded. I looked at the box Tanjiro normally would carry. Curious to know what's inside, I wiped away my tears and kept looking. The box then opened and a girl came out. "A demon!" I yelled. "Yes but not exactly" Tanjiro said. He then looked at the girl "good afternoon Nezuko, did you have a good sleep?" he asked. I saw the demon girl come up to me. I was scared.. But.. she pat my head. I calmed down. "Wow, she's certainly different.." I said. "Yes, this is Nezuko. She is a demon but would never eat a human, instead she sleeps.. She is also my sister" he said. "I like her," I said as I started getting used to her. I smiled. Then I noticed someone coming out of the fog..
