- Awesome Music:
- The latter half of Episode 12. Episode 12 also has Kanata pretty much stopping an entire war from happening with Amazing Freaking Grace. If that doesn't count as a Moment of Awesome, nothing does.
- Also "Servants of Fire". Especially when it plays during Takemikazuchi's big reveal.
- The Morricone-esque score as Rio and Kanata are walking through the town in episode 10, which is itself a stripped-down version of "Servantes du Feu".
- The opening song, "Hikari no Senritsu" by Kalafina.
- Complete Monster: Colonel Hopkins, also known as "The Demon of Vingt", is the leader of Helvetian Army's Ninth Independent Mobile Division who, prior to the main story, manipulates one of the members of Helvetian's 1121st Platoon, Noel Kannagi, by reviving an ancient weapon known as "The Invisible Reaper" in order to provoke war against Roman Empire. This resulted in three cities ended up being destroyed and Noel traumatized by the events. In the present day, when the members of the 1121st Platoon taking care of the unconscious Roman Empire soldier, Aisha Aldola, Hopkins then tried to take over the platoon, planning to use Aisha as the scapegoat of the war in order to prolong the conflict between Roman and Helvetia. When he overhears the news about the ceasefire of the Roman Army via the Citizens of Seize, Hopkins dismissed it and took the citizens as a hostage. A sadistic Blood Knight at his core, Hopkins justifies his atrocities by claiming that war can advance human civilization.
- Die for Our Ship: The Roman Emperor got a ton of heat from Kanata/Rio shippers and yuri fans for marrying Rio in the end.
- Epileptic Trees: 4chan took to this series like moss to... something wet, had several Wild Mass Guessing threads on the setting, the characters and the episodes, and set up a wiki to gather them all.
- Fan Nickname:
- The series itself has been referred to as K-On! season 2 or Military K-On! due to the similar art style and the fact they're both about anime girls playing instruments.
- Also called /k/-On from time to time (/k/ being 4chan's Weapons board).
- And War-On, and probably a whole host of other, similar names. Sadly, no one seems to be going for Guns-On...
- The series has also been jokingly named Call of K-On! Moe Warfare 2.
- "Grace" for the blond trumpeter in the flashback. Real name, Princess Iliya. (Incidentally, her name was in the credits for episode 1, but who reads those, amirite?)
- "Tank-kun" for the Takemikazuchi.
- AIJOU YUUJOU is actually titled "Girls, Be Ambitious".
- Les Yay: See the Ho Yay tab.
- Memetic Mutation: Usage of the term "speculah" appears to have originated here and was later adopted by Puella Magi Madoka Magica fans.
- Moe: Perceived similarities to K-On! aside, the series is definitely one of these.
- Nightmare Fuel: The corpse of the nameless soldier in episode 7. Especially when he grins, telling Felicia to commit suicide. Even worse is that it's all Felicia's hallucination, so really, she nearly talks herself into dying.
- Tainted by the Preview:
- People had some choice words to say when the first animation artwork came out, revealing K-On!'s art style, instead of Mei Kishida's original concept art◊.
- Others got tainted by the credits roll. A series by the guy who directed Elfen Lied and written by the author of Mai Hime suggested a certain artistic direction, and were dissapointed when it turned out they were only right about the Break the Cutie part.
- Tear Jerker:
- A good few in episode 7.
- And the ending of episode 10.
- I... you... same.
YMMV / Sound of the Sky
