Kiryuin Aoi's trainee. Happy Meek isn't based on any particular racehorse (though there IS an active mare named after her as of 2026) but she seems to be the only genuine and original white horse of the franchise (dominant white is an extremely uncommon color for throughbreds; all the other white-haired horse girls were actually based on gray horses). That being said, she is likely modeled either on Hakutaiyu, Japan's first white horse or on Shirayukihime's several descendants (like Sodashi herself).
Happy Meek is a horse girl with shortwhite hair (usually portrayed as an off-white), pink eyes with a flower hairclip over her left temple and an ornament made out of small flowers around her right ear (although, in her case, this might be irrelevant).
The player's trainee races against her in the URA Finale.
