カルストンライトオ(ウマ娘)
[[Umamusume]] character. A sprinter horse girl that pursues the path of "The Fastest". She is a horse girl whose calm and collected exterior belies her straightforward personality, her love for [[cat]]s, as well as her obsessions with straight lines.

She is notable as the first character based on a horse descended from Matchem's sire-line. This means that [[Godolphin Barb (umamusume)|AI 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 also 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 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.
