- Awesome Music: The anime has one of the most fabulous soundtracks in the series, starting with "Nep Symphonia" in its very opening scene.
- Base-Breaking Character: As usual, Nepgear especially with episode 4 after she first turns into HDD. The Conquest Ending casts a long shadow on her reputation. She does, however, still have fans, who view this episode as a Moment of Awesome.
- Iris Heart is either super cool and awesome and does things her way, or a creepy sadistic lesbian rapist and a Karma Houdini.
- Ear Worm:
- Les Yay: Think the games already were brimming with this? The anime is taking this trope Up to Eleven!
- It's all but stated that IF and Compa are "friends with benefits", if Compa's semi-naked pic in IF's cellphone is any indication.
- Nepgear enjoys being Vert's little sister in episode 6. Warm breasts, indeed... During this exchange Vert calls the angry Neptune a jealous sister-in-law. In addition, what Flower Motif is shown during this scene? Lillies.
- Episode Eight has Vert rubbing lotion on Nepgear and copping a feel. Not to mention things going "Just as planned."
- Episode 13 has two Verts getting rather... "friendly" with each other.
- Memetic Mutation: Noire's screaming in the English Dub.
- Narm: Despite the originally parodic-jovial character of the original series, the anime sometimes tries too hard to be serious. Needless to say, this does not work? Vert especially suffers because of this, since almost every scene with her participation has at least one shot on her chest for Gag Boobs, usually with audible Jiggle Physics.
- Arfoire attempts to steal the CPUs powers early on, and has some success. The way she first shows this? By using Neptune's Cross Slash...which is something anyone with slight proficiency in a sword could do.
- Rescued from the Scrappy Heap: The anime adjusts some of the character interactions, personalities, and traits with its adaptation, almost as if in response to how these characters were perceived in Victory:
- Plutia was one of the most hated characters in the game by certain groups of people, but the anime viewers reaction to her anime counterpart is mostly positive and have demanded more from her in the games.
- This could be said for the heroes in general considering their personalities in Victory. Neptune is less of a Jerkass as for the rest of the CPUs.
- Their enemies are undoubtedly evil unlike Victory, where they were more polite and approachable than the "Heroes".
- Nepgear is no longer a Butt-Monkey and her desire to become strong is from her finally getting over her codependency with Neptune.
- This also goes for IF and Compa who were returned to their Action Girl Personalities. This goes double for IF!
- A lot of this appears to have been writers testing the water with these changes, as a lot of the positively recieved adjustments were included in the CPU's appearances in Hyperdimension Neptunia Re;Birth1.
- Superlative Dubbing: While the usual debates apply with regards to the quality of the dub overall, the fanbase is in near unanimous agreement that the dub's version of Noire's infamous scream is infinitely better.
- Tear Jerker: Episode 10, when Neptune had to say goodbye to Plutia and an amnesiac Peashy and when Peashy remembered Neptune only for her to vanish as she said "Neptuna".
Neptune: (looking at the crayon drawing Peashy made with a tearful smile) P-ko...
- "Ito (Thread)", the ED used in that episode, does not help.
YMMV / Hyperdimension Neptunia the Animation
