For me and many other people, Ninja Scroll and Ghost in the Shell provided the introduction to contemporary anime. Although the backgrounds were breathtakingly detailed in Ghost in the Shell, the characters were nicer in Ninja Scroll.
Finding cels of NS scroll is a challenge because most were destroyed by the studio. The remaining ones usually show Kagero or Jubei being hurt in some way. I quickly learned that characters don't smile often in this movie either. Finding good cels of the bad guys is even harder.
In the scene above, Kagero is happy for the first time in the movie. I don't recall her being happy before this scene, but this is also the last time she's happy because she's on her deathbed.
