Osaka has added a new rough image to his site, in the sailormoon section: it's a sequel to the original pic of Sailor Moon being tickled. It looks terrific -- I can't wait to see that one, and the second Velma rough, finished!
The name is given as Setsuna rough phase 2. I thought it said Serena, another name for Sailor Moon, I think. Who's Setsuna? Presumably one he's already done, or why would it be phase 2?
She is Sailor Pluto, basically a gate keeper as I recall. I remember her from when I saw SM on CN. But its phase 2, because there was an even more rough draft before that one of her.
