well technically every japanese race horse are decedents to ノーザンテースト (Northern Taste) that many speculate is Akikawa Yayoi
Well, neither (the RL counterparts of) Symboli Rudolf nor Agnes Tachyon are. Only Mejiro Ryan is, in this image.
Anyhow, was more joking about Mejiro Dober (and Mejiro Jones plus Mejiro Hilary), who are the RL Mejiro Ryan's daughters and granddaughters (Hilary being Dober's daughter too). Though yes, they are all part of the Northern Taste line, so one can tack on two extra "greats" and switch from Ryan to Northern Taste/Akikawa.
Though, on a closer note, Northern Taste is also damsire (maternal grandfather) to Daiwa Scarlet.
Real-life horse counterpart is the father of Daiwa Scarlet.If you're reading this pool you don't need an explanation.Real-life horse counterpart is the father of Mejiro Dober.
