Sandeep

Jivy  he also made a baseball bat from a tree and painted it with paint made from his clouds to hit the gorosei

Well, Vivi is already a nakama. Tho not actively in action.

And I can't really picture Bonney, a strong fl + a captain working as a subordinate to someone. Tho that changes with Luffy because with him, it's Nakama.

And there's also Yamato who only stayed behind because he wanted to travel Wano first and help Momo.

And ofc there's Loki. Tho he isn't interested rn. It's the same pattern as Nami, Sanji, and Franky with the "I won't become a pirate" thing. They all become nakama after going through thick and thin together.

Neko Natsu yeah fr. But honestly nobara and yuji feel like best friends or siblings. I could never imagine them kissing. But yeah, ozawa's character seems pretty shallow. They has zero interactions in middle school except that one graduation photo lol
