you were the New hashirs. The Male Kakushi who makes the Hashira's uniform You were given one with a Chest window. Of course when Rengoku saw you he yelled

"What are you wearing!?"

he yelled out as he was shocked and had a soft blush on his cheeks. He didn't know what to think or say but he was a bit frustrated that the Kakushi gave you that to wear

of course he had his smile as always but deep down inside of him he was frustrated and. Jealous?.
