The last four episodes are entirely random episodes that don't have anything to do with anything from the series so like me if you haven't seen the series (or in my case finished it) you wont be totally lost. The first (actually fourth) episode is an adventure episode where the cast gets caught up in a weird Dungeons and Dragons game and the only episode that has visible nipples. It also introduces Lala's twin sisters a pair of trouble makers one of which has a mad crush on Rita. It's a fun episode
The second episode is more about Lala's twin sisters as they try to show Lala Rita's true identity (as a perv) and some how end up infecting everyone else in the gang which is a funny good time as it's like all the characters flip flop their personalities during a Cherry Blossom viewing session.
The third and final episode is actually three mini episodes. The first is an episode where the class President accidentally loses her panties after a school scuffle with a Senior delinquent. So the president runs around looking for her lost panties and trying not to let people, especially Rita, know that she's that type of person. She fails rather nicely in doing so.
The second story has Rita's little sister chasing after a thief (who turns out to be an alien) who stole her groceries with the help of Peke. Peke uses his abilities and lets Mikan change into a tight embarrassing outfit to beat up the bad gun only to be saved in the end by her brother who finds his sister in distress and lends her a hand by knocking out the bad guy.
The final part of the story is a Lala and Rita story that finds the two stuck together after Rita picks up one of Lala's many odd tools and discovers that he has an epic grip. But the first thing he grabs is Lala's tail of course we all know how sensitive that tail is so we know where this is going. Lots of hijinks and innuendo later his grip is finally released and all is well.
To-Love-Ru is licensed for the US so it's more than likely that these OVAs will also be picked up sooner or later. It's a fun good time nothing series or important goes on and you can enjoy the fanservice so if you're into that sort of thing you'll like it if your not than you wont simple as that really.
Here's the trailer for OVA series...
