Yami unleashes her ultimate technique: cloning several fake Ritos and having them all lick Mea into submission!
And it almost works, until Rito shows up to return the favor. Some of the fanservice highlights:

Yami creates Rito clones with her hair, and here we get a licking scene that makes up for a mostly talkative manga chapter.
The teaser art for To Love-Ru Darkness 2nd hints at Yami in her darkness form. It’s probably a safe guess that the new anime will conclude at the end of the Yami-Darkness arc, which is the next chapter after this one.
Should be interesting, since the previous anime covered five volumes and was paced just right. Getting this far would mean the second To Love-Ru Darkness anime would cover 6.5 volumes.
I hope my guess is right, because chapter 46 would be a fitting end to a To Love-Ru season, with Rito willingly beasting on Yami’s sexy outfit and body. The next chapter needs to be animated, no doubt.
