Kou's name means "crimson" in Japanese.
Seemingly in reference to both her namesake and the name of her pack, Kou is primarily dressed in shades of red.
She has long, straight, light pink hair and green eyes. In her hair, she wears a burgundy headband that is shaped like a pair of rabbit ears and has gold ornaments at its tips.
Kou wears a long, faded crimson garment with a strapless sweetheart neckline over top of a short burgundy pleated skirt with a white stripe. The center of her top is white with white buttons to the sides; its lower half also has white buttons and stripes and splits below her waist, revealing her skirt. A brighter crimson ribbon is fastened loosely around her waist and decorated with gold ornaments. Kou's sleeves, separate from the rest of her clothing, are crimson with pale pink and white ruffles that extend long enough to cover her hands. She also wears a white collar with a ruffled bib and a burgundy bow, to which more gold ornaments are attached.
Her boots are off-black, have laces, and extend to her thighs; underneath she wears a pair of tights slightly lighter in color.
Kou is always depicted holding a white stuffed bear with light pink ears, hands, and soles. Its eyes are represented by gold ornaments, it has a crimson bow around its neck, and its headband is identical to Kou's. When awakened, the teddy bear is shown holding a cake on a plate.
Kou has been officially described as "a cheery girl with a long history in the world of Arcaea".

Kou can awakened at Level 20 since v2.4.0 by consuming:
- 25 Crimson Cores.
- 5 Hollow Cores.
Stats by Level
- Her maximum FRAG stat translate to 1.80x fragment multiplier.
- Her maximum STEP stat translate to 1.40x step multiplier for world mode.
Kou is especially useful for farming fragments due to the high fragment multiplier. If the player does not have Kanae or an awakened Pandora Nemesis (MTA-XXX), Kou is arguably the best partner to use for farming fragments.
Kou's awakened form was added on October 8th (Version 2.4.0). This makes her the first side story partner to receive an awakened form.
- The bonus is applied on the sum of PLAY, CLEAR, PERFORMANCE and FIRST CLEAR fragment amounts.
- For scores of 9,000,000 and below, the bonus is 10%.
- For scores of 10,000,000 and above, the bonus is 20%.
- For scores from 9,000,000 to 10,000,000, the bonus increases linearly from 10% to 20%.
- The bonus amount of fragments is rounded down to the nearest integer.
