Greetings! I'm trying to identify an anime by a *secondary character*, so I don't know if that's going to make it all the harder. Unfortunately, my memory of it is almost completely obliterated, other than by the fact the character was someone that I absolutely *idolized*.
It would have been in the '90s or early '00s (think 'VHS').
It was an OAV.
It was based off a manga (I only remember that because of looking up the character)
The secondary character was an enormously tall and broad female sumo, who was the bodyguard of the main character.
I remember facial tattoos, or facial markings, but I won't 100% say my memory's accurate there. Likewise, I'm almost sure she had dark hair, but not 100% sure.
She had a surprisingly positive portrayal as a 'sensitive woman' rather than a 'living fat joke'. She was also potrayed as extremely strong (she was a bodyguard after all!). Back in those days, that was so incredibly rare that it cemented her in my head.
I feel like the main character was male. And.... aside from that (and the fact there were other characters but I couldn't tell you anything about them) I can't remember *anything*.
