Debuting only half a year ago with a mere six works in total, she immediately released her retirement piece, announcing her departure from the AV industry. The actress we're introducing today had an AV career even shorter than a summer cicada's lifespan, but in the year she debuted, she created a massive stir, completely overshadowing the other seven rookie actresses who debuted alongside her. She is Mikan Risa from Yamanashi Prefecture in Japan, born on May 18, 1993. At the tender age of 19, she entered the industry in February 2013. What was particularly notable is that SOD never revealed her identity from start to finish, instead using the tagline "Does my sexuality need a title?" for promotion, which piqued immense interest in her background. Amid the mystery, her poster was released, and fans quickly uncovered that she was formerly Emiri Takamatsu, a ninth-generation trainee of the Japanese national idol group AKB48. She was selected in the 2009 auditions and was a contemporary of Yui Yokoyama and Haruka Shimazaki, known as the golden generation. Regrettably, she failed to advance in the 2010 general election and couldn't officially join, though she still participated in many popular music videos and the TV drama "Majisuka Gakuen." However, after her defeat, she vanished for two years, and when she reappeared, she had transformed into an AV actress with the name Mikan Risa. Despite the different fields, seeing a familiar face return to the spotlight brought joy to both new and old fans, and her strong background propelled her to the top of DMM's monthly works and actress rankings. STAR-409: Mikan Risa AV Debut is Mikan Risa's first work, produced to the highest standards as part of SOD Create's AV Debut series. Although she was a newcomer, her powerful background meant that SOD couldn't afford to take her lightly and had to treat her differently from typical rookies. From the cover design to the scripts and interviews in the film, you can see the overflowing sincerity, as she was essentially an idol-level new star. By August 22, 2013, Mikan Risa, who had just debuted six months earlier, suddenly released "Mikan Risa Retirement" as her final work. Although her name had already echoed throughout the AV world by then, she had only produced six works—something you could count on one hand—with no clear reason to retire so abruptly, sparking various speculations. There were rumors that she had only signed for six works from the start, so retiring after completion and contract expiration was normal. However, the oddity lies in the fact that there was no prior retirement announcement; the retirement work contained no interview on the topic, and even several scheduled events were abruptly canceled, which deviated greatly from a planned exit. The truth remains unknown; perhaps she never truly belonged in this world and ultimately chose to leave. But I believe countless fans are grateful for her brief presence.
