Anohana: The Flower We Saw That Day/YMMV
- Jerkass Woobie: Yukiatsu may be an elitist asshole who lives to show Jinta up, but Menma's death left him a whole mess of emotional issues and he does realize how pathetic he is. He does start to get a bit nicer after he is outed as the fake Menma.
- Moe: Menma. Also the kids when they were young and Menma's little brother.
- Most Annoying Sound: Jintan. Jintan. Jintan. Jintan...
- Narm: All the crying and screaming in episode 11, while not being totally uncalled for, can reach a point where it just descends into this and melodrama.
- Puppy Love: All over the place. The unresolved romances of the Super Peace Busters are a main driving point of the plot.
- Purity Sue: Menma has a million good qualities and no real significant flaws. She's selfless, pure, beautiful, innocent, loves everyone unconditionally, and is loved by all in return. Tsuruko and Anaru want to be like her, Poppo constantly sings her praises, and Jintan and Yukiatsu are both still deeply in love with her even though she's been dead for years. This can be explained somewhat with her being, well, a pure and rather innocent little kid even by normal standards before her death, and literally not being able to change or mature from there. She's also a brutal deconstruction of the trope as the series explores the negative effects that having such a person for a friend can have and all the pressure it put upon the other characters.
- Squick:
- Was anyone else a little weirded out when Poppo invited Jinta on a "Jungle Cruise" while pulling down his pants?
- Seeing Yukiatsu sniff out one of a sundress that he bought which looked very similar to the one Menma used to wear weirded out quite a few people. It Got Worse when he used the dress to crossdress as Menma.
- Stoic Woobie: Tsuruko, although she doesn't seem like it until much later on.
- Tear Jerker: The thick air of nostalgia is enough to make for at least one per episode.
- What an Idiot!: Both Jintan and Menma fail to just have Menma prove her own existence to everyone else by simply lifting an object or two in someone's direct line of sight. It's especially noticeable at the end of episode five, when Poppo is intentionally seeking out Menma because he wants to help her grant her wish. Instead of trying to interact, Menma cries over not knowing what she wants to do and instead wishes that she could talk to her friends, leaving Jintan to angrily tell Poppo to stop.
