Project ITOH's novel
- An Aesop / Anvilicious: Your life is for no one but yourself.
- Awesome Music: EGOIST's Ghost of a Smile, the ending theme of animated movie.
- The namesake track in the finale when Project Harmony is activated can send chills down your spine.
- Funny Moments: In the beginning, as Tuan herself remarked in the novel, she came all the way to battlefields just to have some smoke.
The web comic
- Ensemble Darkhorse: Sven has earned a large amount of fan art from the comic readers. Starface appears in a great number of fan art as well, though this is obviously due to the amount of teasers Gekko had been posting out.
- Epileptic Trees: Ever since Gekko introduced Starface early on, people have been mass-producing "who is Starface" WMGs to the point that Gekko and Meedee got sick of it.
- Memetic Mutation: The what-if speculations over Picky being Porky's Pigmask Commander led to the meme involving creating Commander X out of a wide variety of characters. Eventually, Gekko and Meedee said it was getting ridiculous.
- Didn't stop them from getting in on the fun, though.
