The reanimated scene from The Final Chapter

  • The Studio Pierrot logo can be seen on the pinball Anna plays at the beginning.
  • The scene of Lum and Ataru doing arm-wrestling has been reused and reanimated in The Final Chapter, although she is wearing her high school uniform.
  • Ryūnosuke wears Ultraman's suit.
  • Kyōko Otonashi, Yūsaku Godai and Ibuki Yagami from Maison Ikkoku make a cameo among the students.
  • This is the last episode to air in 1984.

Differences from the manga

Both versions are practically the same with anime original scenes but the end differs in both versions. In the manga:

  • The story begins with Lum noticing Anna in her high school uniform being harassed by Soban's gang.
  • Lum doesn't use power wristbands.
  • After Lum becomes exhausted as the effects of the pills decrease, Ataru gives a ball to Soban to keep him busy while Lum rests for 3 minutes. Sakura asks Lum what she's been swallowing, and she claims they are vitamins to not disappoint Anna.
  • After Shinobu and Ryūnosuke hit Soban together, Anna tries one pill that Kotatsu-neko got in a dustpan while sweeping, and realizes it's not vitamins as she breaks a tree with one punch.
  • It ends with Ataru digging a hole and burying Soban in it after Shinobu lures him there, and Anna thanking Lum for showing the importance of courage despite having used steroids. And as Anna departs and the duel appeared to be over, Soban resurfaces under Lum and company, implying that the duel is starting again.
