I wasn't too sure if I got the characters right, so feel free to change them to the proper ones if I was mistaken.

Looking at the hairstyle that girl isn't Yumi. The other girl doesn't looks like Crazy Sachiko; and the "Original" thing on the left side makes me think that this pic isn't from Marimite.

Ok thanks for the info. I guess the site I got it off of must have tagged it wrong then.

Uh, wait. That's just my impression of this pic. If you have the source AND the ORIGINAL source says that those people are Yumi and Crazy Sachiko then revert the changes I've made.

Well it's just from another tag systemed site. It was tagged "maria-sama ga miteru" there, but with no character names, so I searched a bit and tagged the character names based on who they looked like the most to me.

I'm gussing it might have been a mistake that they tagged it "maria-sama ga miteru", or maybe it's just the way the artist drew it, and it only resmbles them.

I don't have an official source, just how it was tagged over there, so I'll let you call the shots on this one.

Okay then. They really don't look like Yumi and Sachiko, but I could be wrong too.
