Popular, or apparently not so popular, ero-tentacle manga To Love-Ru only recently concluded its negatively received anime adaptation, but now it looks as though the manga too will be concluding shortly, or rather, cancelled.
The strong suspicion that it will not live out the year, or at least the spring, emerges by way of its poor positioning in Weekly Shonen Jump’s popularity surveys, which also happen to be the major determinant of whether a title is cancelled.
Those titles finding themselves poorly positioned invariably tend to have suddenly accelerated storylines and unexpected endings, and To Love-Ru is in just such a position.
An additional reason to consider it in trouble is that it has been moved to the back of the tome, the meaning of which should be obvious.
It may yet pull through and live on as a third rank manga for a while longer, and fans are fervently denying the possibility of cancellation, but the very fact that such doubts are being raised is probably not a good sign.
