Ex-SDN48 idol Serina makes comeback with semi-nude photo book

She’s back. And though in the interim, there have been thousands of Japanese gravure and music idols to keep us more than entertained, we didn’t realize how much we missed the slinky charms of former SDN48 idol Serina (芹那) until we saw her again.

And we see a lot of her this time.

Since in her first photo book release in 10 years, Serina has gone semi-nude — showing off her more mature and experienced, 36-year-old body.

She graduated SDN48 — remember, the sexier version of AKB48? — way back in 2012, after which we heard little about her.

Now she’s making a jukujo comeback with a self-titled photo book released in Japan this month.

For the shoot, she poses lavishly in lingerie and swimwear to show us her long legs and buttocks. If you like her ass, you get to see it nude — albeit covered by a translucent skirt. And then underwater, she points her naked butt toward the camera with a cheeky smile on her face.

All these glimpses of her butt remind us of the tabloid scandal 10 years ago, when she was snapped apparently returning home after a night at her boyfriend’s, and revealing the thong she was wearing.
