Katsuragi's Kai/remodeled form. See post #1997016.
In her kai form, she disposes of the kimono entirely, and wears a pleated skirt, asymmetric fingerless gloves, with one being an elbow glove, and black thighhighs to create zettai ryouiki. Her armor also includes an armored belt and both forms show off her midriff. Like Amagi her green furisode reflects the fact that she spent almost her entire service camouflaged.
Her quiver in kai form has paper-charm-like arrowheads on her arrows, turning her into a hybrid of the two prevalent CV styles in the game (shikigami-base and archery-base). Also in kai form, a flight deck is suspended off of the left of the rear of her armored belt, along with a mockup of her bridge and several AA turrets as a counterbalance on her right.
