That's sister as in "your big sister", definitely not as in "nun".

Towering over most people and willing to throw down in and out of the ring, legally and underground, Sister Roo looks like a punk who'd rather beat you down than talk to you. With dense enough muscle to kanga-kick a car, who'd be surprised?

But rather than dumb muscle, she professionally trained in wrestling and kickboxing, and delights in showing that she's quicker and more dangerous than just being strong.

Underneath that brusque exterior is a golden heart though, as 90% of her violent work is done in the protection of downtrodden and lost children. She even has a warehouse lair, like the TMNT movie! Except it's actually an orphan refuge.

She's their "big sister" and God help you if you get on her bad side.

(Lizet is fantastic for drawing her aaaa!)
