Green
Kuina learned quickly to look out for green hair because it meant a duel.
A rush of adrenalin.
A green-haired boy that didn't shrink back to fight her again and again and again.
It didn't matter how often she hit Zoro on his mop of unruly green hair; he always came back to rechallenge her.
And Kunia woke up every day awaiting the moment the green-haired boy would fight with her again.
Because the green-haired boy turned into her only true challenge remaining in her father's dojo.
So, Kunia was always looking out for a glimpse of green hair.
