Her name is "Aiko Nakahara". I originally thought she was the most important female member of the SOD Group after Kato Momoka, because she is not only cute, but her first work "Web プロモーションbu" 1st year after joining the company Aiko Nakahara (24) The most shameful AV in the history of SOD female member Naomi自分を変えたいと頑張ってみたところちょっとだけHな事が出ました "これから信び生りです" made the movie fans hate it because she didn't even show her naked body to others in the film. The whole film only saw her looking around, and she was so shy...
Although many fans think such works are boring, at that time many fans expected this female member to become the next Aya Uehara, and by the time of the second work "The Most Shameful SOD Female Member in History" Uneasy and excited でずっと手をぎゅっとしてるドキドキ涙目first SEX をPhotographed ました! Webプロモーション部! 1st year after joining the company Aiko Nakahara (24) アエギ方もわからないほど初心なのにおまんまんはもの奇くヌルヌルに! "Aiko Nakahara has finally been released from the ban and allowed to be fucked by male actors. Although she is still extremely shy, everyone knows that SOD is very patient and will slowly let this female member grow up and thrive:

What then? Then this actress just disappeared!
She left a message on Twitter saying, "I've reached my limit," and then she was gone. I think this was SOD's biggest setback in the second half of last year. If she had been properly nurtured, Aiko Nakahara's popularity might not have been lower than Momoka Kato's (Kato Momoka), who recently transitioned to an AV actress. But you know, I know, and even I know, there are too many examples of actresses in this industry who quit just like that. Besides feeling regret, I don't really know what else to say…
But miraculously, after Momoka Kato (Kato Momoka) became an AV actress, Aiko Nakahara also came back!
She appeared under the name Koharu (小春) in the AV preparatory production company MGStage, and it's clear she's completely abandoned her identity as Nakahara Aiko: in the film, she plays a beautiful 20-year-old college student who was deflowered, having not had sex for a year before (damn, filming doesn't count). Because she hadn't been penetrated in so long, she was very aroused, and the male actor quickly finished her off.
Although she's still shy, Nakahara Aiko, having shed her SOD employee persona, is clearly much more comfortable in front of the camera now. I don't know why she left so suddenly, nor why she came back, but since she's back in this industry, I hope she does a good job, after all, everyone had such high hopes for her in the first place…
Good luck!
