Like everyone here, i'm very frustrated about the axing of this manga.
But let's take this ending as it is. It's quite nice. I was afraid of a finale too naive, but I think what we got is okay. Also, I'm surprised the author really made the "hero" end up with the frog.
Also, totally called the fact that would end up going the same way as her "father". (and damn, call me mad if you want, but I swear this was ship teasing between her and Taddy).
Anyway, it's was a nice ride, too bad it ended up too soon. I hope the author will be able to make a sequel or reuse the characters in another story.
