* Chapter 60 where Haruka get's a birthday cake and eats it with the rest of the team.
* When Haruka runs into the safehouse in chapter 109, after hearing the tale of exactly how Mamoru lost his eyesight; she hugs him.
* Seeing how much Jesus, the world's best assassin, cares for his students even in the midst of a life-or-death battle. The moment he hears gunshots from Ashe and Shiedabra's skirmish, he drops his staredown with Mamoru to rush to her aid.
* In Special Chapter: The Wall, there's something extremely satisfying about seeing Alfa and Papa successfully reunite the boy with his mother. (And, of course, watching Alfa pummel the men who hurt the boy earlier.)
* Chapter 202 is where [[spoiler: Haruka confesses her love for Mamoru and even kisses him after he is beaten to a pulp for perhaps the first time in the story. The rest of the chapter after that is quite a TearJerker.]]
* The very end of the manga (chapter 214), where not only [[spoiler: Mamoru and Haruka are reunited]]... but [[spoiler: after a seven years TimeSkip, [[WeddingFinale they get]] [[EarnYourHappyEnding married]].]]
