SPOILER ALERT. DO NO READ IF YOU HAVEN'T FINISHED THE MANGA. YOU HAVE BEEN WARNED.

I was sad that it ended, but I really loved how Tamiki Wakaki ended the series. ~ I kind of felt sorry for Chihiro at the end of the Goddess arc, so I hoped she had a great ending too. :3 I expected Keima to end up with Elsie or Tenri or something. XD The fact that Elsie became his real sister made it so much better. Although I was hoping for a chapter showing how it would have went if Keima chose one of the other girls.

I was satisfied, but I felt absolutely terrible for Tenri. She was my favorite character and I felt really sorry that after everything she went through for him and all the help she have, he did absolutely nothing.
The part about Elsie was cute though. I'm happy for her.

^ Agreed, I really felt bad for Tenri especially the last part, where Diana's cheering her up. That part was actually very depressing for me.
