Funny / Arpeggio of Blue Steel

• Takao is a veritable gold mine of funny moments in the manga:
  • In Chapter 22, Takao attempts to confess her crush to Gunzou... and instead demands the vibration warhead and data.
    • Hyuuga's dumbstruck reaction on the flub pushes the comedy over the top.
  • Chapter 20 has Takao snuggling her Gunzou body pillow.
    • A bonus page in the seventh volume shows other assorted belongings of hers: books on strategy board games, do-it-yourself scale models of the original I-401 and Takao, a picnic set, a complete navy captain uniform set and Gunzou body pillow ver2.0 (now in casual clothes).
  • Takao and Gunzou shakes hands in Chapter 31. She manages to keep her composure until he turns around and then she just stares at her hand almost as if saying "I'm not washing this hand ever again".
  • Chapter 41: "The jig is up Tsundere Heavy Cruiser."
• Chapter 20, Captain Komaki dreams about asking Hibiki to be the Sonar Officer. With... interesting subtext.
  • Then there's the pages of Komaki trying to ask her out just pages later and Kirishima's reaction to Haruna... Well, let's just say Chapter 20 has a LOT of funny bits.
• Shizuka's spec ops uniform includes a badass helmet with a skull design on the opaque face shield... and heart-shaped Blush Stickers.
• Hyuuga has a pair of giant rocket fists she really enjoys using against the invading army troops.
  • She then unleashes what's essentially an Ork WAAAGH!!! with an army of Mecha-Mooks she built while bored.
• C'mon, a Haruna-shaped hole in a warehouse wall?
• Haruna and her humongous coat. "Shakii~iim". Or, in the Crunchyroll sub: "Shazam!".
  • Naturally, this trait got abused by Makie and Maya in the 8th episode.
    • Listen to the music that plays when the coat is off. Yes, they really used that song
• In Chapter 16, we finally see Takao making landfall at Iwo Jima. It was... not smooth sailing. Her getting beaned in the face with a cruise missile was especially hilarious.
  • Gets a Call-Back in Chapter 51 when Ashigara gets beaned with a torpedo when she fails to sink I-401.
• Kirishima as Youtarou the bear plush. The anime-only scene at the dinner table was especially hilarious.
  Haruna: Kirishima... stuffed animals don't eat carrots.
  Kirishima: I am well aware of that.
  • And starting with the intro for Episode 6... Bear!Kirishima and Kirishima show up side-by-side.
  • Bear!Kirishima trying to swim in episode 8. Turns out that the plush body absorbed so much water that it renders Kirishima immobile when soaked enough. To remedy this, Haruna wrung the water out.
• The ending of Episode 7 is completely identical to the normal ending... Except the Mental Models are replaced with the ships, complete with the orientation of each Fog.
  • Speaking of Episode 7... the way Hyuuga reveals her mental model to the others.
• Chapter 50 of the Manga has Iona temporarily in charge of... Herself (oh such shenanigans Anthropomorphization brings), when the Fog suddenly attacks while they are at depth, catching the crew totally off-guard, leading to this moment:
  Iona: Start the engine! [...] 401! Slow to the side! Sou! Lock the doors that aren't along Shizuka's path.
  Sou: Yes.
  Iona: Kyohei! Insert corrosive warhead torpedoes into tubes 1-4! Insert active decoys into tubes 5 and 6!
  Iona: Go get dressed Shizuka.
  • Ashigara's taunt to Iona is reduced to ridiculous "argle-blargle" when she dives without putting up a Klein Field around her Mental Model.
• Early in episode 11, Haruna remarked that losing Takao was a great loss... only for Takao to appear on several screens a few moments later (and finally being spun by Makie, complete with swirly eyes on Takao's end). This is quite a Mood Whiplash after episode 10's serious Heroic Sacrifice.
  • Even more hilarious, is Haruna of all people/ships being the Deadpan Snarker about Takao's situation and crossing the line twice, saying "It's not too late. Go into the light."
• Episode 12. Takao's mental model is restored. Her very first action is to tackle Gunzou.
  • For added funny, just as when Iona is about to approach Takao from behind, Hyuuga clings on to her hard.
• Ashigara and Haguro walk off into the distance in Chapter 62 in a very intrepid fashion, only come running back in a blind panic as Iona runs aground directly on top of them.
• Chapter 43: For most of the conversation in the limo, Maya is seen looking in wonder at the land-bound world with her face pressed against the window. She's still in this position when the limo stops and the rest of the characters get out. Turns out that Haruna had locked her in that state to escape Maya's constant chatter and no one else had noticed.
• Chapter 43: I-402 referring to Takao as "Tsundere Heavy Cruiser". Guess the I-400 sisters really do think alike.
