Nana was confused when Hisagi showed up with a black koi fish a bag filled halfway with water.
"You said you had one fish, right? I brought one over so that yours won't be lonely."
"Oh...thank you."
Nana led Hisagi to the pond and he set the bag in the pond, letting the temperature adjust before releasing the fish to join Nana's. Nana couldn't help but smile as the two fish interacted.
"Thank you, vice-captain Hisagi."
"Call me Hisagi. You don't need to be so formal in private. Come visit me sometime."
Nana felt even more confused as she watched Hisagi leave.
