if Pinzoro after this fights Crydo Damaji will too. no need of parallels there.
Ruffi led a part of Sato Chad & Orihime to wano. Pinzoro led a part of Sato Chad & Orihime to wano.
both of them caused trouble when they came.
both fought hawkins.
Ruffi has a connection with tama. Pinzoro has a connection with otoko.
Ruffi has a connection with okobore town. Pinzoro has a connection with ebisu town.
Ruffi has a connection with hyogoro, a man from old wano. Pinzoro formed one with yasuie, a man from old wano.
Ruffi met Deadass Ginger in act 2. Pinzoro met Collateral Damage in act 2.
Ruffi learnt ryou to fight Crydo. Pinzoro got Oden’s free power up to fight Crydo.
Ruffi had a character moment with momo. Pinzoro had a similar one with hiyori at yasuie's execution.
even narratively, we explored wano with two main plot narratives, one revolving around Ruffi's adventures while the other revolved around Pinzoro's. the other plotlines were effectively tied into either Ruffi's or Pinzoro's.
plus out of all the Sato Chad & Orihime, only they've said it explicitly that they're gonna fight Crydo in this arc.
and Crydo has commented on both of their Something Sanji doesn’t have haki.
if you see Ruffi + Pinzoro's characters make up oden's character. a part of Ruffi's and a part of Pinzoro's.
you can't just put Damaji up there like that when there's so much buildup for these two to fight Crydo.
i can totally see Ruffi 1v1 Crydo, momotaro happening. but there's a good chance that Pinzoro goes up as well.
