Serena's POV:
When we came inside the train until we heard 'UMAI' as we almost got a heart attack. We found Kyojuro as he was enjoying the bentos, he's really enjoying the bentos so much. Also, the people were watching him because he keeps on saying 'UMAI' a lot.

"This guy is the Flame Pillar?" Zenitsu asked Tanjiro as he nodded at him. "He honesty looks like a glutton" Zenitsu said as I have to agreed with him because Kyojuro dose look like a glutton and saying 'UMAI' (Or should I say 'tasty') every time too. Then Tanjiro came up to Kyojuro as me and Zenitsu were behind him. Also, he was trying to get Kyojuro's attention as I was watching this.

"Oh wow... I did not expect this coming" I said to myself as I was still looking at Kyojuro until I some, how got his attention on me. "Serena-chan! My darling! It's good to see you again! These bentos are so tasty!" Kyojuro said as he was done eating the bentos. Tanjiro and Zenitsu were surprised of this as they turned to me.

"Serena? How did you meet Rengoku-san?" Tanjiro asked as I sweat nervously. "I was just walking even, went to sit down on the bench until he came across me" I said as I was smiling nervously at them until Kyojuro broke the silence.

"Actually, I was doing my own business until I hear a song, I never heard before! I started to follow the voice until I came across her! Serena-chan had a beautiful voice, I every heard!" Kyojuro said as Tanjiro, Zenitsu & Inosuke turned to look at me even, they were surprise again. I was sweating a lot of how much attention, I was getting now.

"SERENA-CHAN?!! YOU NEVER TOLD ME, YOU CAN SING?!!" Zenitus said as he was so loud even, getting the people's attention again too. This was really embarrassing. "Zenitsu! Please, calm down! Your getting a lot of attention here! And, yes... I sing some time, when I feel sad or happy..." I said as I look away from them even, I was feel my cheeks warming up from embarrassment.

"Serena? Can you sing for us? I really want to hear your voice" Tanjiro said as he gives me a warm smile. I looked down on the floor as Kyojuro, Tanjiro, Zenitsu & Inosuke were still waiting for me to sing. I took a deep breath in until I begin to sing to them.

When I finished singing to them, they were amazed of me until the people on the train started to clap and cheering for me.

"Serena-chan! You have the most beautiful voice in the tire land!" Zenitsu said happily as Tanjiro agreed with him. "We should be careful! I don't know, when a demon is going to appear but I can protect you, Serena-chan! If you're closer!" Kyojuro said as he pulled me closer to him. I end up blushing red as I feel Tanjiro & Zenitsu glaring until Zenitsu realised, what Kyojuro said.

"A DEMON IS GOING TO APPEAR ON THIS TRAIN?!!" Zenitsu asked in fear as he was very loud. "It will!" Kyojuro said as his eye twinkled even, I set across from him.

"IT WILL?! NOOOOOOOOOO! SO WE'RE GOING TO A PLACE WITH DEMONS BUT NONE ARE GOING TO SHOW UP HERE?! I'M GETTING OFF!" Zenitsu said as I was really scared now too. "This is way worse, then the evil forces! I have to take care of those evil force, when they tried to take the energy from the people and trying to take the silver crystal too! I hate this so much!" I said as I started to cry like a baby.

"Umm... Serena? What are you talking about?" Tanjiro asked as I realised, what I said. I turned to them, I saw Kyojuro, Zenitsu & Inosuke were looking at me still. "It's nothing! Anyways! Kyojuro? How many people are missing?" I asked as I change the subject.

"In short period of time, more than 40 people have disappeared off this train. We sent a number of swordsmen here but none ever returned! That's why I'm here! A Hashira!" Kyojuro said as I started feel something and, it was not good too. "Something is not, right here... If Luna was here with me. She can know, what's going on" I said to myself as I was looking around until the door of the train opened.
