Differences from the manga

The plot differs quite a lot with reality losing its structure being anime original, and only the scenes of Ataru drinking Lum's can of eye drops, his nightmare and him trying to make up with a drink only to be hit by Mendō and the boys being adapted.

  • The story starts with Ataru refusing to share sweet potatoes with Lum and driving her away with garlic smoke, which is what causes her to have an eye infection that makes her unable to stop shedding tears.
  • After being hit by the boys, Ataru speaks with Sakura about that matter then sees her discussing with Ran then walks in town thinking.
  • Lum had to keep on crying until Ten got her a new can of eye drops she used on her spaceship.
  • It ends with Lum returning to Ataru's room and finding numerous potatoes Ataru bought for her, thus deciding not to tell him what the can really was while eating.
