You are The {choose breathing style} Hashira! It was your birthay...but it seems like nobody remembered...you were a bit upset and sad about this, but you understand that others have missions or just forgot. That's fine...you just wished somebody just said "Happy birthay" to you today...

About half an hour later

You were walking back home from a mission, still a bit sad. You entered your home and...when you turned on the lights...Everyone jumped and yelled happily "HAPPY BIRTHDAY!". You were caught off guard by that.

Shinobu:"You didn't think we forgot, did you?"

Mitsuri:"We would never!"

Rengoku:"We were here the whole day, preparing your birthday party!"

Sanemi:"Whatever...not like I care, anyways..!"

Tengen:"This is gonna be the most flamboyant birthday party you ever had!"

Muichiro:"Happy birthday! Oh,wait, I already said that-"

Obanai:"We wish you many happy returns."

Giyuu:"I hope you're not upset about being alone for most of the day..."

Gyomei:"Happy birthday, dear friend."
