Nobody believed us when we said he heard Tasigi's teardrop. All Sanji haters said he made it up and it was only for a badass line
Then we had the moment in Onigashma where he legitatemately heard a full conversatiom with CoO.....one that Luffy couldnt hear. But of course he just used his ears and not CoO. Even though he literally closes his eyes and the CoO SFX is literally there. And it absoutely makes zero sense how he can zero into a conversation in a war filled with screams.
And now its undeniable proof that he can hear sounds with CoO since Nami is their to backup the statement....and make sure Sanji is actually talking about sounds.
Again hearing sounds with observation haki is very rare. Enel could only replicate this using his Goro Fruit.
Dont get this confused with the voices in Coby's head btw. Voices is another way of saying Precense.
Hearing voices (which means feeling precense) is outright different to hearing teardrops, screams and conversations which is actual hearing with CoO. Only Enel and Sanji has shown this.
Anyways now we have proof that this is all CoO....lets recaliberate.
- Sanji can hear a literal teardrop 100s of meters away with CoO
- Can use his CoO to single out a conversation between 2 people and hear them inside a war filled with screams
- Can hear someone screaming within a body of water without being inside and being meters away from it.
Absoutely insane shit. Sanji defintely specialises in hearing CoO, possibly even has better feats than Enel without using a DF.
Sanji's advanced observation haki could specialise in hearing of heartbeats
