This is the paramedic who found his family among the dead victims. I thought it was only his mother who got killed, but I was mistaken. But his sister seems to have survived only.
They're telling him to calm down but he fell to the ground saying: My family. My family.
The man consoles him saying: We're all one family here. Each one of us has lost their family. Look, my sisters are in there. We have to get back up. You're strong.
AU: Kuina lived and her father was supportive of her ambition. He sent her to Wano to learn the way of the swords so they meet again when Zoro arrived at Wano.
I just rlly wanted to design a giant Kuina after seeing how big Kiku is :)))
