* Hisame remembering the moment she decided to do her best for Sami.
* Hanako's flashback monologue of her relationship with Tarou.
* The last page of Chapter 62, when Samidare admits that she loves Yuuhi more than she does the Earth (this makes a lot of sense in context).
* Chapter 63. All of it.
* The ending of the series. Easily one of the best endings to a story such as this one.
** Adding to the above, the moment when Samidare gave them all hand-made plush dolls resembling their animal companions.
* The three most romantic moments in the series are what amount to two promises of mutual suicide, and a promise from one to commit mass murder on the other's behalf. Each one manages to be somehow heartwarming, chilling, and sweet all at the same time.
