Set after To Love Ru Darkness (manga)
Things had finally calmed down at Sainan High after a few love confessions to a certain Harem protagonist. However, choosing to wait until things calm down even further, Rito is now aware of his own love for two different girls, both of which love him back. But when things get too quiet, there's always something that goes wrong.
A creature made of pink slime appears on Earth, and has the ability to turn anyone it touches into bombshell bimbos! After contact with a few females, Rito and friends try to step up and trap the alien menace before it causes further discord. Will they succeed? Will our heroes save the Earth from becoming a planet wide orgy? Or will they fall under the same curse as well, and become doomed to have sex for a potential eternity?...better question is, who ever said they were heroes?

Lala put on a smirk which didn't seem to her at all. "Okay, Rito how about a deal." "A Deal?" "Yes, if you tell Haruna how you feel about her. You won't have to kiss me, but if you don't by the end of tomorrow you will have to." Before Rito could even comment Lala left the room. He hurried up to open the door to confront Lala about this whole observed situation, but when he looked down the hall all he saw was a black blur.
