tastiera (racehorse)

Italian: "(Musical) Keyboard". Follows his family's musical theme naming.

Japanese racehorse. Sired by Satono Crown and foaled by Partitura (from Manhattan Cafe).

Winner of the 2023 Tokyo Yushun (Japanese Derby) and the 2025 Queen Elizabeth II Cup (the one in Hong Kong). However, both of his major wins were marred by the incidental death of another racer: Skilfing at the Derby and, most tragically, Liberty Island at the QEII Cup.

He is a bay horse with a distinctive, roughly heart-shaped star marking as well as a pastern on his right hindleg and a sock on his left hind leg.

In the context of Umamusume, the horse is often drawn with his sire's Umamusume counterpart, especially in reference to the simultaneous ascendancy of Season 3's main cast and their RL progeny.
He is also directly referred to as the "Horse girl with green eyes" in Satono Crown's ending.
If depicted as a horse girl, Tastiera will almost always have the distinctive "heart-on-a-stem" marking in the same way Satono Crown has her distinctive "crown" marking.
