Story (7/10) - As with Darkness, these OVAs were good. Doesn't really pertain to the story. You aren't really missing anything by not watching these. There are a few flashbacks, funny and perverted accidental mishaps, and maybe a thing or two that the main series won't show.
Character (8/10) - With the great character development in Darkness, the OVAs add a little more depth to some characters and their feelings.
Enjoyment (7/10) - The level of enjoyment felt in this series follows through, but some of the Ecchi scenes, were starting to become a bit much.
Overall (7/10) - These were nice little shorts to watch, now there's nothing stopping me from watching the last installment of the To LOVE-Ru series: To LOVE-Ru Darkness 2nd!
