Just about any moment when the Kongou sisters are onscreen and off-duty.
Kongou's introduction:
Kongou: AD...MI...RAL! Burning Love! *glomps Ooyodo*Mwah, mwah!Mwah, mwah! Admiral...huh? This isn't the admiral, this is...Ooyodo! Ooyodo: I am Ooyodo, yes. Nagato: Unfortunately, the admiral is away at the moment. Kongou: SHIT! But, next time I won't lose! I'm the one who's going to win the admiral's heart!
Haruna attempts to lure Shimakaze into a trap, using a "KonColle Seductive Kongou Photo Album" as bait. It works...on her sister Hiei.
Later, Mutsuki and Yuudachi find Kongou in the factory, dreaming out loud:
Kongou: Hahaha...Admiral...my ears...my ears are ticklish, haha!
Fubuki heads into the docks, hoping to meet Akagi. Instead, she gets a facefull of Atako's funbags. After she extracts herself:
Atago: What's wrong? Did you come here to the docks because you're hurt? Your nose is a little red.*pinches Fubuki's nose* Fubuki: No, this is... Atago: You should get in quickly. It's open now. Fubuki: *nose is still pinched* Uh, but... Atago: Okay, say "banzai". Fubuki: Banzai? Atago: *raises arms and gainaxes* Banzai! Fubuki: *raises arms*: Banzai...? *Atago grabs the hem of her shirt.* Eh? Atago: Fubuki, heading out! *pulls off Fubuki's shirt* Fubuki: Whaaa?! W-wait! Mutsuki: What should we do? Yuudachi: We'll just have to go back, poi. Atago(offscreen): Okay, take it off! Banzai on the bottom, too! Fubuki(offscreen): B-Banzai!
The fleet arrives at Yamato's island base:
Kitakami: Yeah, it's definitely summer. Ooi: Kitakami-san, are you okay in this heat? If you want, the two of us can go in those bushes, and -- Snake: Hiss! Ooi: EEEK! A snake! Kitakami-san, it's scary! Fubuki: This really is the place, right? Kongou: You always worry too much, Buki! There's no problem at all! [aside whisper] Maybe... Fubuki: You just said "maybe", didn't you?! That was a "maybe"!
Later, the girls take a break at the beach:
Kitakami: [Atago's] breasts are amazing. *Atago gainaxes* Hard to believe [Akatsuki[1] and Atago[2] are] both fleet girls. Ooi: Yeah, but bigger doesn't necessarily mean better. *Yamato's breasts enter the scene with a cannon sound effect.* Kitakami: Wow...
After pushing herself to the ragged edge of destruction, Fubuki finally gets her remodel. She's very happy with the results on her 'backpack', her leg-mounted torpedo turrets, her arm cannons, and then she examines her chest...
Fubuki: Huh? *looks at Yuudachi's chest[3], then her own* Huh?! Yuudachi: You didn't really change, poi? Mutsuki: I'm glad. Fubuki: I'm not!
