Waitus, like Crimson, was created offscreen by Rainbah

He studied and then taught Judo.

He had contacts with Gonzalo Clan, where developed hunger for money.

Now he is somewhere, beating goobers to half death, they go to doctor(which is Gonzalo) , paying them for healing, and then getting beaten up again.

And Crimson....i hasn't get alot of info about them, they are just existing.
