OVAs (often interchanged to OAV) stand for Original Video Animation. It's basically how the Japanese refer to anime that goes straight-to-video. OVAs are episodes usually from 30 to 60 minutes long that offer higher production values than TV animation, yet they aren't movies. After the TV show ended, the Urusei Yatsura manga continued to be written by Takahashi. The OVAs served to animate some of those manga stories for fans.

This section has short synopses for each Urusei Yatsura video release in the order they came out. These include the OVAs, a TV special, music video collections and others.

I Howl at the Moon
Lum makes Ataru some sakura-mochi for a night time picnic watching the cherry blossoms. But Lum had made a mistake and accidentally made tsukimi-dango instead (which are traditionally eaten during moon viewing). Supposedly when eaten at the wrong time, it causes lycanthropy in humans. The next day Ataru finds himself becoming a werewolf along with Onsen-Mark who also ate some. Lum must now force Ataru to take the antidote before 24 hours are up, or he'll remain a wolf forever.

Goat and Cheese
This is where the OVAs started to lose continuity and use varying animation styles that didn't quite gel with Urusei Yatsura's established style. Still this is a pretty faithful adaptation of Takahashi's story. On a hill within the Mendo estate there is a statue of a goat. Mendo tells his friends that it is forbidden to take a picture in front of that statue for it brings bad luck since the real life goat hated getting his picture taken. But Mendo's father takes a picture of them together anyway. According to his father, a phantom of the goat will come to eat the photographs and when that happens, those in the photo will die as a consequence. So with the help of Sakura they watch over the photographs all night. A night of terror they would never forget.

Now Ataru has girly-eyes and can't pick up girls without scaring them away. What's worse is that Ataru is spreading the disease all over town.
