To have Sasuke with Sharingan available in Anko's shop,you must first complete Story mode. Then, go to Anko's shop and buy the next Story mode chapter (at the bottom of the list). After you buy that chapter, complete it. Then, return to Anko's shop and buy another chapter. Complete that chapter. Repeat this process until you have completed 30 chapters (the original 20 chapters that were available by default. and 10 more that you purchased).
