Regarding the good ending Options

[Anubimon]

I just beat this game and screwed myself out of seeing the best ending because I transouled Algiery without knowing you needed to keep her alive.
That being said I was wondering if anyone could give me a synopsis of the ending or if possible a video.
To be totally honest I signed up for this site for the sole reason of asking this question and doubt I'll ever be back other than to see an answer and say thanks.
Any help would be appreciated, thanks.
