Heartwarming / The Lucifer and Biscuit Hammer

  • 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). If this doesn't bring a tear to your eye, then you have no soul...
  • 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.
