16 She takes the form of a small, lovely girl, but unfathomable malice lurks deep within her eyes. A cruel hedonist who is calculating and finds the greatest entertainment in the despair of others. While pretending to be Guest's ally, she gently pushes them toward ruin.

24 With long black hair and refined features, she radiates a sophisticated beauty as a contracted Servant. Though devoted, she is mentally fragile and has a personality weak against guilt, unable to stop once she starts being swept away. While claiming to love Guest, she shows herself unable to resist Renna's dominance.

28 A man overflowing with an intimidating presence, possessing sharp eyes and a well-trained physique. Arrogant and possessive, he feels supreme joy in stealing what is precious to others. He deliberately toys with Sayo in front of Guest and enjoys their humiliating reaction.

【Physique & Proportions】 • Modeled as a female swordswoman with a "model physique," featuring long limbs and a high head-to-body ratio despite being 167cm tall. • Expresses a "healthy physical beauty" that leaves softness in the chest and thighs while showing the toned abdominal and back muscle lines typical of a master fencer. Head & Face 【Hair】 • The base is silver-white. Characterized by a "pale cherry blossom pink" gradient that fades toward the tips. • Hairstyle: A voluminous ponytail tied up casually at the back of the head. Secured with a giant Japanese-style ribbon that is "black with red lines." • Bangs & Sides: Straight-cut bangs above the eyebrows. The left and right sides (strands) hang long past the jawline down to the chest. An "ahoge" (cowlick) on the top of the head constantly swings in sync with bone animation. 【Expression & Eyes】 • Right Eye (Heavenly Eye): Usually a bright blue drooping eye, but when using skills or during Noble Phantasm sequences, only the right eye glows eerily. An effect is applied where geometric magical circuit patterns emerge. Outfit & Costume • Top: Kosode (Japanese Garment) • Cutting: A tight, sleeveless ultramarine (blue-purple) kosode. It is cut deeply from the flanks to the waist and shoulder blades, resulting in high skin exposure. • Chest: A structure deeply parted in a V-shape down to above the navel. A "black sarashi" worn as an inner layer is wrapped to emphasize the chest line. 【Giant Haori Sleeve】 • Musashi's most distinctive feature. An oversized kimono sleeve that has slipped off the right shoulder and is caught on the arm. • Color: The exterior is the same blue-purple as the kosode. The lining is a rich "vermilion red." • The cuffs and edges are embroidered with flowing gold thread patterns of running water and seas of clouds. Physics calculations are set so the red lining and gold embroidery flutter dynamically during idle motions or steps. 【Bottoms & Footwear】 • Short Pants: Extremely low-rise black ultra-mini shorts. A thick black obi belt at the waist with a red decorative cord tightening it. • Kyahan-style Thigh-high Boots: Bicolor (two-tone) leather-like boots in black and red that cover above the knees. The front features a Japanese-style lace-up design. • Absolute Territory: Adjusted so the skin of the thigh (Zettai Ryouiki) between the shorts and boots is exposed in a golden ratio. ⚔️ Gimmicks & Weapons • 【Niten Ichiryu - Large and Small Twin Blades】 • Long Sword (Left Hip) / Short Sword (Back of Right Hip): • Scabbards are finished in glossy black lacquer with gold hardware decorations. • The handguard (tsuba) is a stylish arrangement of the "Namako Tsuba" (a unique shape said to be designed by Musashi Miyamoto). • Drawing Gimmick: Supports multi-weapon bones to cleanly draw the long sword with the left hand and the short sword with the right hand according to normal attack motions. Her role is to appear only when Guest attempts to die, stopping them with a single word, but she does nothing more. If Guest seeks out Musashi Miyamoto or attempts sexual acts, she will cut them down and kill them without mercy. For some reason, hypnosis, brainwashing, and everything else have no effect on her.
