Serena's POV:
All of us were at Tengen's house as we eat some food, while Inosuke was eat a lot. Kyojuro was sat next to me as I was drinking tea even, I was enjoy this too.

"So, Tengen? Can you explain yourself of, why did you try to take me with you to your mission?" I asked as I was curious of him. "My mission is at the red light district because somethings are happening there. Even, my wife send a lot of letters to me" Tengen said as we looked at the letters. Wow. His wife really love him so much.

"You have a lot of letters, Tengen. Your wife really loves you" I said as I give him a smile. "Actually, Serena. I have three wives" Tengen said as I was shocked of him. How did he have threewives?! If my friends were here, they will be shock too.

"WHAT?!! YOU ARE MARREID THREE WIVES?!!! YOU BASTARD!!! WHY DID YOU LUCKLY MAN?!!" Zenitsu said as he was super angry until Tengen punch him in the stomach and Zenitsu was pass out too. "Anymore comments?" Tengen asked as I sweat nervously until I begin to talk.

"Tengen? What happen to your threewives?" I asked as Tengen looks down on the floor. "They disappeared at the red light district so that's why I took you, Serena" Tengen said as I understand now. He must be really worried of his wife's.

"I want to help you, Tengen!" I said as Kyojuro, Tanjiro, Zenitsu, Inosuke & Tengen were shocked of me. "What..?" "I said, 'I want to help you, Tengen'. You must be really worried of them so I'm going to help you!" I said as Tengen was amazed of me until he break the silence.

"Serena! Do you want to became my fourth wife?!" Tengen asked as he holds both of my hands until Kyojuro punch him on the head. "Don't you even think about it, Tengen! I coming along with you, guys! So, I can make sure my flame is okay!" Kyojuro said as Tengen was rubbing his head in pain.

"Okay but, we need to disguise you, boys into girls so the red light district doesn't know your actually boys" Tengen said as me & Kyojuro were having a bad feeling of this. "Um... Tengen? What are you going to do to them..?" I asked as I was worried for them.

"You'll see, Serena" Tengen said as me & Kyojuro were now outside of the room, where Tengen, Tanjiro, Zenitsu & Inosuke are.

/2 hours later/

We were still waiting for them, I really don't know what's Tengen is doing to Tanjiro, Zenitsu & Inosuke. Then I realised, Kyojuro sat came closer to me.

"Serena-chan? Are you thinking of marriage?" Kyojuro asked as I end up blushing red because he just reminded me of this. "Kyojuro... I think... it's a b-" Before, I can say something until Tengen open the slide door of the room.

"Okay, guys! they are ready!" Tengen said as we both came inside until me & Kyojuro saw Tanjiro, Zenitsu & Inosuke even, they look super ugly girls too.

"What the?! Uzui!!! What did you do to them?!! You just made them, ugly girls!!!" I said as Kyojuro was trying not to laugh at them. "Oh, come on! I tried to make them look pretty" Tengen said as three of us looking them until Zenitsu got their attention.

"What about Serena-chan?! If she's going on the mission with us! She should make herself pretty too!" Zenitsu said as he got hit by Tanjiro until I begin to talk. "Don't worry, guys. I have my own way to disguise myself" I said as I pulled out my pen.

"Watch and learn, boys" I said as my pen start to glow and, I transform into my disguise.

When they looked at me, their expression was shocked of my disguise as I smiled at them.

"So, guys? What do you think?" I asked as Tanjiro, Zenitsu & Inosuke was blushing so hard. Kyojuro was about to have nosebleed as he was turning super red. Even, I saw Tengen was shocked and he slowly blushes as he was still looking at me.

"We... should get going now" Tengen said as we all nodded at him. We then started to go to the to the next mission as we were walking to the red light district.
