Both Luffy n Zoro befriended old man and saved little girl. Otama probably a koruzomi and Hitetsu probably Oden dad. Interesting that Toko shows up again. She might be from the 5th clan we seen in Lden flashback. Seems both will turn out to be important in Wano politics. Hitetsu probably is Pden father too trying to make amends for not stopping the massacre of Orochi people.
