Umamusume character, voiced by Mochizuki Yumiko.
A sprinter horse girl that pursues the path of "The Fastest". Her calm and collected exterior belies her straightforward personality, her love for cats, as well as her obsession with straight lines; she talks fast, thinks fast, and always takes the most direct path to her goal, no matter how nonsensical. The result is a girl who can act downright bizarre as she tries to do anything and everything as quickly as humanly possible, though she is infact one of the fastest horse girls on record when it comes to raw running speed.
She is notable as the first character based on a horse descended from Matchem's sire-line. This means that Godolphin Barb finally has a direct descendant to cheer for, and hence why she repeatedly made appearances in her campaign.
The real Calstone Light O is notable for holding the Japanese record for 1000m (≈5 furlongs in US/UK terms) on Turf (53.7 seconds during the 2002 Ibis Summer Dash, in Niigata, which has since then been lowered to 53.5s by Puro Magic at the same event in 2026), which is the reason for the Umamusume version's obsession about becoming "the fastest". As the Ibis Summer Dash is one of very few straight races in Japan, she is also obsessed with going straight and straight lines in general, often to the point of spurning curves or anything that curves.
