This is the sequel of Sora no Otoshimono

At first I just started reading this manga because I knew this was the same creator of Sora no Otoshimono, a manga that deserved a better anime adaptation but because of the studio ended up bankrupt it finished very badly.
The first chapters, although they did not have a consistent story, were entertaining and I personally like the silly humor they have.
[SPOILERS]
~!But at chapter 13, the story has taken a 180 degree turn and now it's a more serious and interesting tone, since the characters from Sora no Otoshimono (Tomoki, Ikaros, Sugata...) have been introduced to the plot and it seems that the protagonist is Sugata's brother.

I hope Suu can make interesting sequel for the original story of Sora no Otoshimono, I always thought it had a very abrupt ending.
