This is Carlos, a friendly schoolteacher with a dangerous and hidden pastime.
During the day he teaches the kids and teenagers, and at night his whole demeneaur changes.
He's a pirate... To put it bluntly...
His crew were slaughtered by the navy during a raid, and he was the only survivor. He went undercover in the nearest city, becoming a teacher.
No one suspects that he's the one behind all the thefts and strange happenings, after all... Who would suspect such a kind, child friendly person?

Hey guys, new image, more for the fact that I needed a reference than for the sake of the drawing. But, enjoy it all the same.
Illomarty out.
