Story (7/10) - This fun little OVA is to commemorate the 10th Anniversary of the franchise by animating the two-part bonus chapter at the end of the To LOVE-Ru Darkness Manga, and does it spot-on. Lala makes an invention, doesn't work. Rito somehow gets effected by it, and everyone works to resolve the issue. Enjoyment (7/10) - I enjoyed this little OVA as I did the other OVAs of the series, a fair amount. I wasn't even aware of this until MAL notified me, thanks for that. It was nice to see everyone again after having finished watching/reading the series a while ago.Overall (7.4/10) - This was a nice little trip down memory-lane for fans of the franchise. It just goes to show, sometimes, no matter how hard you try, you'll end up in compromising scenarios that you won't be able to get out of; but that doesn't mean it won't be entertaining for others.
