Everything gone wrong....

At the red entertainment district
Tengen was talking about his plan to Zenitsu, Tanjiro, Inosuke, and Muichiro.
Tengen: "Listen up, when you're here first look for my bride."
Inosuke: *stuffing Mochis in my mouth and eating*
Tanjjro: *nodded and sip on cup of tea and pour some tea for Muichiro*
Muichiro: *Also sipping on some tea with Tanjiro
Zenitsu: * mad* "THIS IS OUTRAGEOUS! HOW DARE YOUASK US TO FIND YOU A BRIDE FOR YOURSELF!!!" *yelling*
Tengen: "WHERE DID YOU GET THAT IDEA! YOU IDIOT."
Zenitsu: "NOPE, I HAVE MY SAY!
Tanjiro: "Zenitsu!"
Muichiro: *watch and is annoyed ofc of Zenitsu screaming*
Zenitsu: "I'm so sure that no one would like a screw up oddball like you that has no luck with ladies. Just because, you want a wife there isn't a reason you using your breathing style."
Tengen: "YOU'RE A IDIOT! IM TALKING ABOUT WIFES!"
*meanwhile, Inosuke just eat mochis watching and grinning. Tanjiro and Muichiro are also watching enjoying their tea*
Tengen: "So, as I was saying... Yes I do have three wives."
Zenitsu: "WIVES, WIVEE, WIVES!!! WHY WOULD YOU HAVE THREE OF THEM!!!"
Tengen: *Knocks out Zenitsu* "Is that a problem?" *Looking at Zenitsu on the ground annoyed and his fist clenched*
Muichiro: *He just quite ignoring Tengen or Zenitsu. He just sit next to Tanjiro silently*
Tanjiro: "So, what do we do exactly?"
Tengen: "Three of my wives are accomplished ninja. I sent them to get closer to a customer and since then I located three most likable house. So you guys will help me search those three houses and gather information for me."
Inosuke: "Your wives must be dead, don't you think?"
Tanjiro: *shocked that Insouke say that*
*Tengen punched Insouke knocking him off and he was stack on top of Zenitsu*
Muichiro: *handpalmed and mumble* "Geez, I swear these two are idiots."
Tanjiro: *Sighs*
Tengen got makeup and clothes dressing Tanjiro, Zenitsu, Inosuke, and Muichiro up.
The first house they went to is the Sumiko.
Lady: *sitting with a man* "oh my, these girls must be quite homely girls, aren't they?"
Tengen: "Isn't there any way to reconsider?"
Man: "I'm sorry bu-
Lady: *face lit up* "I don't mind taking one. Not a problem."
Tengen: "Go ahead and pick one."
Lady: "Can I take her?" *point at Tanjiro*
Tengen: "Of course."
Tanjiro (Sumiko): "I promise, I will be useful and work as hard as I can."
Tengen: *walking around with Muichiro, Insouke, and Zenitsu*
