For starters, any time you hear "Salva Nos", expect the awesome to commence.
Though it's debated exactly when she reached her true pinnacle of Awesome, Kirika's fight in the third episode of Noir — in which she manages to not only give an Offhand Backhand shot to an enemy behind her, but uses popcorn to find them — was probably the moment we realized that she really was that good. Mireille's expression at this was priceless, btw.
An appropriate tag to this scene via one website was "Kirika isn't a Ninja...she's a Witch." Other "holy frijoles" scenes includes her killing someone with objects such as sunglasses, student IDs, and toy trucks. Later she shoots two mooks through a single gunshot hole yards away. Then there was the part where she faces about fifty Triad gunmen in broad daylight, with no cover. Granted, she had Chloe's help, but dang....
The time she takes out a squad of soldiers by herself in a No-Holds-Barred BeatdownIn the Soldats village is another impressive fight, though it's incredibly brutal, involves her taking a hostage and using him as a Human Shield, and ends with her dispatching said shield with a shot to the head without even looking at him. Cripes.
Though it's more of a wince moment than a CMOA, Kirika's last fight with Chloe can be summed up in two words: Olive Fork.
Not to mention the entire final episode, when both girls show of their best stuff against the Soldat nuns, including one with a sword.
Also, although it was not animated quite as clearly as it might have been, Kirika does snap a grunt's neck with his own tie in the very first episode, by grabbing it then jumping down to a lower level or something. Spatially it was a bit hard to follow, but it was hardcore.
Although not a CMOA by some people's standard, this troper watched in awe as, when Chloe walked into their flat, Mireille held a gun on her and we all got tensed for an action scene — Kirika asked: "Would you like some tea?" I also think that this was the most priceless moment in terms of Mireille's expression at the time
This politeness did not, however, stop her carrying a 3-inch long fork up her sleeve — with which to KILL Chloe if the latter ever let her guard down.
Which, in a CMOA for Chloe, she never did.Then, at least.
In this troper's opinion, Kirika's CMOA comes when she's being chased by a thug up the spiral staircase of a bell tower in Sicily. She kills him by tying a bell rope to her ankle, and diving down the center of the staircase, shooting him as she passes him in headlong flight. It doesn't hurt that the music playing then is 'Salva Nos', IMHO the most outstanding piece of music in the series.
This troper finds even more awesome to remember that the same thug has broken both Kirika's hands, and she still manages to shoot, by tying the gun on her hand.
In one scene where the girls are once again running from goons, Kirika gets shot in the arm and can't get her fingers to close around her gun handle (muscle and/or nerve damage preventing the motion from completing). A few seconds later, one of the goons goes down, and we see Kirika step into the scene, having tied her hand in place around the gun.
Chloe taking out Shaoli in a matter of seconds. Made more awesome by the buildup throughout the episode and the one before it establishing Shaoli as a badass.
In episode 17, we have Mirielle hunting down and killing a sniper.
