X Drake has actually been an undercover Marine this whole time.
Scratchmen Apoo was actually working with Kaido’s crew prior to his alliance with Kid and Hawkins.
So as you might have noticed, false identities or mystery identities is a huge recurring theme in Wano arc.
Anyway 2 characters are still missing here: Tenguyama Hitetsu and Tama.
Let’s start with Tenguyama Hitetsu. He is a kokeshi doll collector and Robin found a collection of Kokeshi dolls in the capital castle’s Poneglyph room.
I think Tenguyama Hitetsu is the Poneglyph’s caretaker and knows how to write the ancient language, too. Momonosuke needs to learn it to resume his Kozuki legacy, but Robin can’t teach him as she has to accompany Luffy.
Next up is Tama. Why on earth is a little girl protected by the last free Samurai in a super secret strawhat village and where on earth are her parents? Strange right?
I think that Tama is a Kurozumi. The last Kurozumi. Tama is essentially Orochi’s heir.
By hooking up with Momonosuke, the blood feud between the Kozuki and Kurozumi will be put to an end.
