Hisagi was surprised to see Nana outside of Seireitei. He happened to see her by chance when he went to pick up some sake for Kira.
She was carrying a basket of groceries and she was currently crouched at a booth that sold koi fish.
"Iwaizumi-san?"
Nana jumped at the sound of Hisagi's voice but she quickly regained her composure and bowed.
"Vice-captain Hisagi, I didn't see you."
Hisagi regarded her with a nod.
"Looking at fish?"
"I have a fish in my room. I was thinking about getting another one so it won't be lonely..." Nana shook her head and gave him a small smile, "I'm sorry, I must sound strange. Good bye, vice-captain Hisagi."
