Yuko Ogura

Yuko Ogura (おぐら ゆうこ, 小倉優子) (born November 1, 1983 in Mobara, Chiba prefecture) is a popular Japanese idol and model who typically aims for the cute, innocent schoolgirl look.

Ogura regularly, if not entirely seriously, claims to be one "Princess Apple-Momoka" (りんごももか姫) of the apple-shaped planet Korin (こりん星). This is apparently an in-joke dating back to her middle school days. Having an alternate name was trendy at one point, and one of her friends told her that she looked like a Momoka. She liked the name and still uses it today.
It has been suggested—notably by the Guitar Samurai, in song—that Ogura has carefully calculated and cultivated a quirky, oddball persona for herself. Ogura denies this.
