She has a poetic and artistic name, and before her debut, her professional fields spanned several areas. Besides serving as an etiquette instructor, she also worked as a flight attendant for a major airline. Although there are rumors that this is just a character setting provided by the film company, so its authenticity is up for debate, the author wants to say that regardless of whether it's true or not, with her extraordinary appearance and outstanding demeanor, even if you call her a palace noble or a princess, I'd accept it without question. So, let's reveal her true identity! She is Matsushita Sako, born on September 30, 1990, in the cold Hokkaido. Matsushita Sako debuted in May 2015 as a "side-job AV actress" and became an exclusive actress for "SOD", relying on her stunning figure of 165 cm and F cup, along with her elegant posture that exudes a thousand charms in every gesture, plus her beauty that can rival idol stars, making her destined for massive popularity from the moment of her first appearance. RBD-867: The Female Teacher Toyification Plan. Matsushita Sako stars in Attackers' Female Teacher Toyification Plan series. The plot involves her playing the class teacher, whose student named Kawakazu has a father who is a rapist and a mother who is a sex worker, leading to a shameful family background that results in constant ridicule and criticism from peers and teachers. To avoid bullying and verbal abuse, he chooses to be chronically absent from school. Thus, Matsushita, to fulfill her duties as a teacher, visits Kawakazu's home. However, during their conversation, she discovers that his personality is completely twisted, and he even expresses admiration for his father's rape behavior, planning to do the same to her. When Matsushita tries to resist and leave, it's too late, because the tea she just drank was spiked with sedatives and aphrodisiacs. Ultimately, she realizes that his previous absences were all part of a plan, and the target was her herself... What's curious is that after debuting for a year, in May 2016, Matsushita became an exclusive actress under "Attackers". She released five stewardess-themed works at SOD, which not only quickly built her a substantial fanbase but also laid a solid foundation for her future status as an actress. So, why, when she was already thriving at SOD, did she move to Attackers? The exact reason isn't clear, but just when most fans and viewers thought the gentle and elegant Matsushita couldn't handle the new company's style, she silenced them with her actions, and the results were surprisingly effective, mainly due to the chemical reaction from the contrast, using her inherent mismatch with themes like adultery and slavery to add depth to the works. She also took the top spot in the "Most Popular AV Actress" poll for viewers aged 45 and above in the AV actress popularity survey held by FANZA on October 12, 2018. In February of the following year, with her work "During the Four Days My Girlfriend Was Away on a Family Trip, I Went Wild with Creampies with Her Sister", she once again claimed the double championship in FANZA's DVD sales ranking and the cumulative sales ranking for actresses.
