(late reply due to work; I just got home)
AW YEAH, HERE WE GO!
I'll leave a few to choose from just in casd you prefer a certain design.
Feel free to ask for more if you want; I don't have too many other actual gijinkas, though my Boss Emporium tab has the majority of 'em (though a lot still lack a design due to my own lack of motivation).
Overboss is a cruel business owner in the middle of an industry war. Should boss finally end the war, they will run their city and the surrounding areas. They are very calculated, but also won't hesitate to resort to morbid threats against a company - you do not want to hear the phrases "you're fired" or "letting you go"; They're quite literal in boss' case.
Bossman, another evil boss, but more selft kept. Preferring to hide in the shadows and let their underlings to their work for them, boss normally stays in their office, but also wanders their surrounding area at night.
And if you're okay with fandragons, I'll leave my girl, Rye!

I messed up pieces of her outfit (mainly her poncho), so have the character for reference too. xD
She's a tough gal, though has grown soft for one of my OCs, known as Weaponsmaster (though she'll also refer to him by his birth name: Wilko, and she's the only one aside from WM's parents that gives comfort with his real name - to the point where Wilko actually asks her to keep using his real name).
But regarding her character otherwise, if you know of Cookie Run, that's her. xD
If you wanna draw her with her real weapons, that's cool too. Understandable if you'd rather not though. :)
