(1983)
When everyone in town recieves invitations to Ataru's wedding, they are shocked to see that his alien sweetheart Lum is not the bride. Eventually they learn that when Ataru was playing games as a little boy, he stepped on a girl's shadow. Unbeknownst to him, the girl was from another planet where stepping on one's shadow is a form of marriage proposal, and now she and her family have come back to see that Ataru follows through on his promise. If he manages to get out of this without being killed by her folks, he'll still have to avoid being torn apart at the hands of Lum. ec0 Written by Jean-Marc Rocher
