Unlike those fake fans Akazaya, Yamato wouldn't buy the fake Oden for a sec
True, but the Akazaya are going to meet another person claiming to be Oden after getting their hearts broken by Kanjuro.
You say this as if Kanjuro isn't going to use a fake Oden or (more likely) a fake Kin to trick Yamato, Momo & Shinobi.
Kanjuro is totally going to pose as a fake Kin to trick Momo and Shinobu. We'll automatically know it's Kanjuro if Oden appears, but Kin could be real or fake and leaves us suspicious. I wonder how good Yamato's CoO is, or if Sanji will come in clutch here since he's been missing for too long.
