Technically you did not work as a drug store employee but after seeing your brother get terribly sick and not to mention how horrible he organizes the medicines. You were normally a demon slayer that Shinobu surprisingly did not see around often

But she would go to this herb place almost everyday. At times just having conversations with you. When she arrived today you passed her a bag of herbs and some medicines and told her it was for free

"I didn't see any free herbs sign out there."
