Amagi Happiness
Amagi Happiness (Amagi Hapinesu) is a supporting Uma Musume from Umamusume Pretty Derby: Star Blossom, a Tracen Academy student aligned with Team Alkes. At 163 cm tall and born on May 13, she carries herself with a presence that feels quietly distinctive: relaxed and easygoing on the surface, yet marked by a composed, almost old-fashioned air. She is described as free-spirited, and that combination gives her a memorable flavor—someone who seems unhurried, but never aimless.
Her known story gives that temperament real weight. Amagi Happiness spent about four months traveling across Japan alongside Kawase, Team Alkes' sub-trainer, before returning to Tracen Academy. That detail alone sets her apart. Where some characters are defined by constant forward momentum, Amagi Happiness has a broader horizon to her, shaped by movement, distance, and the sense that she does not belong solely to one place or routine.
When she did return to the track, it was for a major test: the Satsuki Sho, where she raced against Narita Brian and finished second. It was a strong showing, but also a costly one, as she was injured afterward. Rather than settling into a conventional comeback narrative, her biography turns once more toward the road: after the race, she resumed traveling with Kawase. That arc makes her feel a little elusive in the best way—less a fixture of the academy halls than a figure who passes through with quiet significance.
Within Team Alkes, she is connected with names such as Sakura Laurel, Sakura Chiyono O, Sakura Bakushin O, and Yoshino Prevail, and her trainers are listed as Gorou Akeishi and Tsubaki Akeishi. Even without an exhaustive public profile, those associations place her in notable company. She is also an original character rather than one officially stated to be based on a real racehorse, which gives her an unusual place in the wider cast.

Although Amagi Happiness is officially an original character, she is strongly implied to represent the Japanese racehorse Sakura Super O. Both share a birthday of 13 May, and Amagi’s performance against Narita Brian closely recreates Sakura Super O’s most famous race.
Probable Inspiration: Sakura Super O
Sakura Super O was a grey Japanese stallion foaled on 13 May 1991. He was sired by Sakura Chiyono O, winner of the 1988 Tokyo Yushun, and was owned by Sakura Commerce. He raced 11 times between 1993 and 1997, recording three wins and four second-place finishes.
His career highlight came in the 1994 Satsuki Sho, the first leg of the Japanese Triple Crown. Starting as the ninth favourite at odds of 47.9-to-1, Sakura Super O produced a strong late run to finish second behind the dominant Narita Brian. He finished 3½ lengths behind the winner while holding off Fujino Makken O for second place.
Following the Satsuki Sho, Sakura Super O was absent from racing for almost two years. He returned in March 1996 and later won the Kumpu Stakes over 1,800 metres at Tokyo. He made one final appearance in the 1997 Fuji Stakes before retiring from racing.
Amagi Happiness reproduces Sakura Super O’s Satsuki Sho result by finishing second to Narita Brian in Star Blossom. Her extended travels and physical troubles may also reference the long interruption to Sakura Super O’s racing career.
Because the connection has not been officially confirmed, Sakura Super O is best described as Amagi Happiness’s probable inspiration rather than a definitive real-life counterpart.
