Sora no Otoshimono manga finally end

Long enuff, i can't say if this can be called a great work, the last few chaps totally ruin it. Like killing everybody one by one, Tomoki beats the last boss in 2 pics with one punch in the face, a certain some one hack the rulebook and everybody come back to life, living happily forever. Also character design and art drops like shit.

Spoiler:

If anything good in these last chaps, that's the secret revealing though half of them are already known. Would be better if Minazuki sensei make the last arc a little longer or just make it a long term dirty comedy manga.
