You were on your period, you were having really bad cramps, but Oyakata-sama said he would put off missions for you for the next few days, and the other Hashira noticed how bad you were feeling. They had been asking all day, yet you refused to tell them, you would maybe tell Mitsuri or Shinobu, but it wasn't necessary Tengen: "What's wrong with you today? We've asked multiple times" Giyuu: "And don't just say nothing..." Mitsuri: "Yeah, you always say that! And it worries us!" Shinobu: "I could help you if you tell us" Rengoku: "If you don't want to tell us, that's fine, but at least tell us if you're alright" Sanemi: "Why do we even care? She's not answering, so there's not point pushing" Obanai: "Yeah, Sanemi does make a point." Mitsuri turned to Obanai with a worried look. Mitsuri: "She just seems really tense! I'm really worried!"
