I thought the same, same old attitude, same eyes and hair lol Definitely a brother or his father (=・ω・=)
It's possible they're related. We already saw Rum and Ginger's family and there was a resemblance. I hope they interact soon so we'll know the answer.
Baron is Mananan's father so you were right the first time. I don't remember exactly what chapter it is that they mention it but it's one of the first few that Mananan appears in
They defintely have the same ass and shoulders *ahem*.
Is Baron Mananan's father? Or some other relative? Because he looks just like Mananan.
