Serena's POV:
"Hey, guys! Look, who I got!" Tengen said as he puts me down to the ground too. I don't really want him to do that again. It was really embarrassing! When I looked up until I saw Tanjiro dodging Giyu's attack as Zenitsu was watching them.

"Wow..." I said as I was shocked of them until got their attention on me. Tanjiro was the first one to break the silence.

"S-Serena..?" Tanjiro said as I gave him a warm smile at him. "It's good to see you again, Tanjiro. Even, the others too" I said to him as Tanjiro was about to hug me until Mitsuri beat him to it as she was hugging me tight even crying too.

"Serena!!! We thought you were dead!!! We're so happy you're okay!!!" Mitsuri said as she continues to cry a lot. "Mitsuri! Please, don't cry! If you cry... I will cry too!!" I said as I begin to cry even, I was hugging Mitsuri too.

"It's good to see you, Serena" Obanai said as he joined in the hug until everyone joins in the hug too. "Don't do that next time, Serena! You did something risky and, you let Muzan absorb you too!" Giyu said as I smiled nervously at him.

"It's the only way to stop him from hurting the innocent people, Giyu! Also, how did you get here???" I asked them as I was really curious until I saw Tanjiro pulled out something from his pocket. When I looked closer, it was my star locket music. "Here, Serena. This belongs to you. Also, it was your locket. It bring us here to you" Tanjiro said as I took my locket even, I smiled happily at them too.

"So... It's all over now. Muzan is defeated & there is no demons. We can live a happy life too" I said as they nodded at me. "Ara, ara~ We're going to have so much fun" Shinobu said as all of us agreed with her. This is going to be a lot of fun.

/Time Skip/

"I. Need. The. Maths. Book. To. Learn!" I said to myself as as I was trying to reach the book on the shelf. I was actually at the library because... Sanemi told me to come and study at his place even, Genya was going to study with me too. Anyways, I was trying to get the book until I saw Amy even, she saw me.

"Sanemi??? What are you doing???" Amy asked me as she was curious and, she came up to me too. "Hey, Amy. I'm trying to get the maths book from the shelf" I said to her as Amy looked surprised.

"Why???" "That's because... Sanemi told me to come to his place so I can study properly for my grades" I said as Amy was super shocked to hear this. "You're actually going to study, Serena??? You actually changed, when your old friends came here" Amy said as she saw my annoyed expression.

"Amy, you don't get it. He's going to make me work really hard! Even, he's going to hit me on the head with a book if, I'm not concentrating" I said as Amy nodded at me in understanding. "Look at the bright side, Serena. You're going to have a higher grades. Also, your parents are going to be proud of you too" Amy said as I sigh in defeat.

"Your maybe right, Amy.." I said as I continue to reach for the maths book until someone got the book for me. When I looked at the person, it was Kyojuro.

"Hey, Serena! Need a little help here? Also, you free today or night?" Kyojuro asked as Amy looked at him. "Not today or night, Kyojuro. Sanemi wants me to come over to his place so me & Genya can study even, he's going to help us too" I said as Kyojuro gave me the maths book.

"Oh... I see. Maybe, next time because I really want you to meet my mother" Kyojuro said as I nodded at him. "Okay, then. I'll see you later" I said as Kyojuro leave me & Amy alone until she broke the silence.

"Serena..? How many friends do you have???" Amy asked me as I was too tired to answer but, I just told her. "I have a lot of friends, Amy. I need to go now to my next lesson. So, see you later" I said as I borrowed the book and leave the library to go to my next lesson.
