Yyp is right (as always). Scan teams often put fanart in front of the pages of a chapter, and they usually put the artist's name in the corner. In this case, however, they didn't, so I can see why you'd think it's official, but it's fanart; here's the link to the original art http://cheshireplaynwthfire.deviantart.com/art/Captain-Unohana-s-BANKAI-191682873
