To Love Ru Darkness manga volume 9 features story by Saki Hasemi and art by Kentaro Yabuki.

Rito and friends face off against the wrath of a killer body-snatching sword from outer space- and that's actually the easy part of his day! The really tricky part is a little more amorous. Rito's been close to all kinds of gorgeous girls, and Momo's even pushed him to start inducting them in his own personal harem, but there's one thing he's never done with any of them: kiss! Now that Lala's heard about how common kissing is on earth, is it time for Rito's relationships to go to the next level?
