[3] She became the first Mejiro horse to be trained by Shinji Okuhira [ja], after no other trainer wouldn't take her and another filly in.

[3] The name is based on the Aiguille de l'Amone in the French Alps added to the Mejiro kanmei (eponym).

However, her groom Kozo Kojima saw that she had a large abdomen, suggesting that she possessed a high level of cardiorespiratory function.

However, she became agitated soon after the start after bumping in to another horse, and lost momentum, finishing fourth in a five-way race.

[12] After this was, she was moved to the Kansai region and entered in to the Hochi Hai Yonsai Himba Tokubetsu, a trial race to the Oka Sho.

After returning to Miho, she was planned to run in the second leg of the Triple Tiara, the Yushun Himba (Japanese Oaks), but there were concerns as to whether she can win a race at Tokyo due to both of her previous losses being at that racecourse.

[5] After winning the Yushun Himba, she was sent to the Mejiro Farm to recuperate, before restarting training at Hakodate Racecourse in August, with the intent to starting the Autumn season with the Queen Stakes before contesting the final leg of the Triple Tiara, the Queen Elizabeth II Cup (Q.E.II Cup) (at the time the Shuka Sho was yet to be formed).

[5] At the race, she was in the front of the pack, and attempted to take the lead on the stretch, but struggled to do so as she went neck-to-neck with Pot Tesco Lady.

She held on to the lead as she and the other horses entered the final stretch, but she briefly slowed down and was almost overtaken by Super Shot.

However, she managed to hold on to the lead by a neck, making her the first winner of the Triple Tiara since its introduction in the JRA races.

[17] A retirement ceremony was held at Tokyo Racecourse on February 8, 1987, where she appeared wearing the race bib from her Q.E.II Cup.

[18] Her grave is erected inside the properties of the Mejiro Stud, currently the Lake Villa Farm [ja].
