Mx0 wasn't a huge loss because the story got so bad after the cave arc where he saved the two chicks and got closer to them.
After that it was "test of the week" bullshit followed by a small bone thrown to us in the form of him getting 10% black magic (which could have easily been another 10% "of the week" bs), Naruto-style because the WSJ editors wanted the story to drag out. The Mx0 mangaka is known for terrible endings usually because his stuff gets cut.
At least To Love Ru goes somewhere consistently with him getting closer to the girls. With Mx0, he was only interacting with Lucy and the other girls were entirely worthless like in ch 96 when their tits grow G-cup huge for no reason at all and everyone just passes out...
