Calstone Light O is a character in Umamusume: Pretty Derby.
Biography
"What I'm after is the maximum speed. I'll be faster than anyone—faster than a deer, or even a pronghorn!"
She's cool, she's straight as an arrow, and she's hardheaded—for she is Captain Straight-line! In pursuit of "the maximum speed", this stiff-necked Umamusume simple-mindedly and stoically charges forward on her path to the peak of fastness. As long as she's the fastest, she'd be faster than anyone! In other words, she'd be the one with the maximum speed! Anyway, she's undeniably honest and straightforward, being the kind of person who's open about both her feelings and actions.
| Likes | Cleaning, dizzy bat races |
|---|---|
| Dislikes | Quadratic functions, diving |
| Ears | They can hear cats meow from miles away. |
| Tail | She cuts it perfectly straight using a ruler. |
| Family | She can tell what her parents are thinking about from their facial expressions alone. |
| Secrets | For some reason, her white ahoge only ever curves to the right. |
| It was discovered that all of her PIN numbers were set to "1111", so she was forced to change them all. |
Appearance
Calstone Light O, the fastest, has straight, long black hair that reaches her waist, and a distinct solid white cowlick swept to the right side of her head. She wears yellow ear coverings on both ears, and has a yellow tassel shaped ornament adorning her right ear cover. Her eyes are a piercing yellow, with black pupils.
Calstone Light O's racing outfit consists of a dark blue double-breasted jacket with long, frilled sleeves, and a white frilled skirt. The front of the jacket is adorned with golden buttons, and red buckled decorations on the upper arm of both sleeves. The inside collar of the jacket matches the golden buttons with a bright yellow diamond-shaped inner pattern. The jacket also has red colored shoulder decorations, matched by the red colored ascot that Calstone Light O wears. Above the skirt is a leather belt with golden decorations, with a single blue diamond shaped gem at its center. A yellow string is tied around her waist under the belt, the knot sitting neatly where the white frilled skirt is. Under the white frilled skirt are a pair of white shorts and black pantyhose, with a black garter on her right thigh, adorned with a golden pattern running across it. She wears mismatched black and white heeled shoes, with the right shoe resembling a boot that almost reaches her knee, and her left shoe reaching just past her ankle.

Names in Other Languages
| Language | Name | Meaning | Notes |
|---|---|---|---|
| Chinese (Hong Kong) | 金鎮之光 | Light of the Golden Town / Light That Overwhelms Gold / Light That Protects Gold | Translated name by HKJC. The "Calstone" and "O" in the name were ignored, leaving only the "Light" part of the name translated and extended. The true meaning of the name is unknown, as there can be various explanations. |
| Chinese (Traditional) | 浮岩光王 | Pumice Light O / Float Stone Light O | Name used in the TW servers. As "Calstone" was the crown name of Calstone Horse instead of an actual existing stone, it was translated into a different type of stone, which was pumice. "Light" and "O" were translated accordingly. |
