Background
editCalstone Light O was a dark bay horse bred in Urakawa, Hokkaido, by Oshima Bokujo.[1] He was sired by Warning, a British-bred stallion, and his dam was Oshimachia, a daughter of Crystal Glitters.[2]
In 1999, he was offered at the Hokkaido Summer Sale and purchased for ¥18.9 million by Sadamitsu Shimizu.[3] The name "Calstone" was derived from Shimizu's business dealing in pumice (light stone), combined with "Light" and "O" (from the owner's name, Sadamitsu, and "King").[4] He was sent into training with Yuya Ooneda at the JRA's Ritto Training Center, and later transferred to the stable of Hiroyuki Ooneda.[1]

In popular culture
editCalstone Light O is depicted as an anthropomorphic character in Umamusume: Pretty Derby, voiced by Yumiko Mochizuki.[10] She is depicted as a straight-faced girl with a strange obsession with speed and straight lines that extends outside the racetrack. She is single-minded and prefers to do tasks as quickly and efficiently as possible and has a strong dislike for curves, which she regularly attempts to remove from her daily life.
