The ecchi romance comedy manga "To Love-ru" seems to be losing its popularity in Japan. & if it continues to decline (or heck, even stay the way it is), it could face cancellation from Shonen Jump. The speculation arises from the fact that the series hasn't been doing so well in Shonen Jump's popularity poll as of late, which is what SJ uses to determine if a series should be canceled or not. Not only that, but the chapters are now placed in the back of the magazine, also suggesting its popularity is down. If things keep up like this, it could be gone completely a few months from now.
I find the timing of this very odd, myself. The series just finished a very successful anime run. Usually having an anime version run on TV should help boost the popularity of a manga, not the other way around. There's also been tons of more merchandise coming out, including some very attractive looking figurines as well as some
very ecchi video games. So why the manga is on the decline now is beyond me.
