Dont have much details about these figures of Chizuru apart from these scans found by Wcouldx.
A first look of the upcoming 1/5 scale figure of “Minamoto Chizuru” by 4-Leaves ^^ Looks like there will be 2 versions, one is the Human form, and the other is the Fox form. They’ll be up for a whoopin’ price of 13,440 Yen and is scheduled for October 2008 release.
Never heard of 4-Leaves either and searches don't bring up anything relevant.
Quality looks decent but guess we will have to wait n see when more info/pics come up.
BTW, have you seen the oppai shenanigans in the DVD release of Kanokon? If you are an oppai fan then you may want to check it out ^^;
