Menstruation
"Ayato?" Oh he could hear her voice thickly laced with pain and it wasn't from external injures, it was a process that all females humans and ghouls alike had to go through monthly for a week.
That's right.
Periods.
The foulest of weeks for both men and women for obvious reasons
"What do you need?" He asked already knowing that this would also come up around this time of month, henceforth why he was at the market instead of snacking on a taxi driver.
"Pads. Chocolate. One of those heating blankets. Oh no make it two- onee-chan wants one."
"Why is my sister at our place?" He inquired as he walked down the isle over to the feminine needs section much to the horror of some male humans who made faces like he was about to do something crazy and couldn't stop him.
"It's thanksgiving, Ayato! And I know you miss her- don't lie to me." Ayato huffed, "What kind?"
"The regulars, and tampons for onee-chan." Oh how Ayato wanted to scratch his brain with a toothpick are the vile image of- oh no he wasn't going to go there. He grumbled under his breath, "Where's that dumb bookworm?"
"The doves are hunting onii-chan."
"They're hunting us."
"Well we didn't accidentally kill several high ranking members of the CCG while going on a rampage, now did we?"
"Would have been awesome."
"Ayato."
"Okay. okay." Ayato picked up the requested items and went over to the counter, the male clerk gingerly picked up the items like they were going to bite his hand off. Scowling he said- always willing to cause a fight, "You gotta a problem with this?"
"N-no sir! Just- do you want me to put them in extra bags?" Ayato snorted before grabbing the bags and walking out of the market.
