Takamatsu Eri was the embodiment of the "Yamato Nadeshiko" (traditional, graceful Japanese woman) aesthetic. She rarely showed skin. She blushed when asked about love in interviews. She was marketed as the girl you wanted to protect.
As a pioneering figure, her immense success, followed by her sudden departure, opened a floodgate. Her story was a blueprint for a new wave of former idols, and she is often cited as a precursor to later massive crossovers, such as that of Mion Yoneyama (Kirara Asuka) and Shoko Nagai (Yua Mikami). Years later, media reports surfaced claiming she had resurfaced as a high-class escort under the alias "Mari Inoue".

Unlike many AV stars who enjoy long careers, Risa Tachibana (Eri Takamatsu) was a "shooting star." She only performed in a handful of films after STAR-409. By 2012, she had vanished from the industry completely. Rumors persist that she either married a foreign national, opened a small bar in Shinjuku, or simply returned to anonymity.
