WOW! A harem end, and an actual end with some emotion! Do wish it would have showed all the girls grown up with him and wish we didn't see him die, as that is sad.
Honestly, even though it got axed most likely, I enjoyed this series.
I guess a perfect ending for me would have been him having a harem, and then showing us his kids being born and seeing the ghost. As that was the main reason for having kids, to make her not lonely for eternity. Although it would have been even better if they somehow made her become human, and she joined the harem.
But what we got was close to this and honestly great! I am 100% satisfied.
