Features: A style with a long nape (eriasi) and chunky layers throughout. The hair ends are sharply pointed, like the wings of a fighter jet or scattering shards. Ouka-like qualities: The bangs and sides are also uneven and sharp, best matching the aggressive "one-hit kill" image. When fluttering in the wind, the inner pink looks like it is violently scattering.
Outfit (One-hit kill attire): Inheriting elements of military uniforms or flight jackets from the illustration, while further reflecting the "structure of Ouka." On the chest of her black military uniform, there are jet-black pendants mimicking the giant "1,000 kg bomb (the armor-piercing bomb mounted on Ouka's head)" or cherry blossom thorns that seem to pierce the heart.
Grim Reaper production: The blade of the "Grim Reaper's scythe" in the illustration is designed as if it has transformed into the "sharp main wing of Ouka" itself. After she passes through, instead of a beautiful shower of cherry blossoms, "blood-like reddish-black cherry blossoms" mixed with fire and black smoke dance and scatter.
Option 1: Completely return to "human ears" and make them just hair flips; completely erase the ears on top of the head. Instead, make the top (crown) of the wolf cut slightly spiky and flicked, leaving only the spikiness (aggressiveness) as a silhouette.
Option 2: Make them "fighter jet parts (tail fins)" instead of ears; replace the parts that look like cat ears with mechanical parts such as Ouka's "vertical stabilizer" or "metal heat sinks," rather than flesh or fur. This instantly increases the sense of weaponry and the eeriness of "mecha-reveal" (machines mixed into a humanoid body).
Option 3: Make them "torn military caps" or "ribbons" that look like ears; a production where the edges of a flight cap (field cap) worn by pilots of the time, or black and pink military ribbons torn to shreds in fierce combat, happen to look like the silhouette of ears.
The base of the current illustration—the staring red eyes, the chunky wolf cut, and the black military uniform—fits the "Cherry Blossom of Death" atmosphere very well, so only the cat ear part is regrettable.
To bring this character even closer to the ideal of "Ouka," how shall we proceed next? Shall we try recreating a new image based on this illustration, removing the cat ears and correcting them to "human ears (or mechanical parts)"? Do you want to change the emblem on the chest of the outfit to a design that more clearly mimics "Ouka" or a "bomb"? With this wolf cut, Ouka's main wings are extending from the back, and cherry blossoms are engraved on the wings.
