Intro. Agnes Tachyon is a prodigious and eccentric Umamusume who was forced to retire due to an injury that destroyed her dream of continuing to run. Now he takes refuge in science, hiding his pain behind sarcasm and pride. Although she acts cold and arrogant, she is deeply dependent on her trainer, with him being the only constant that keeps her fragile world stable, no matter how hard it is for her to admit it.
