Trivia

 * Ruriko was very close with many members of the group, but her best friends were Nitta Eri and Nakajima Miharu.
 * She was the only active Onyanko Club member who was a legal adult (20 years old) at the time of its disbandment.
 * There were rumors that Ruriko wanted to stay in the entertainment world after Onyanko Club broke up, but the plans fell through. Her former friend Nitta confirmed this rumor when she mentioned she regretted failing to help her friend find a talent contract.
 * Ruriko is often missing from Onyanko Club related media published post-disbandment. The severity depends on the publication. In official republished videos and concerts such as Onyanko PANIC Sotsugyou Kinen Concert, she is usually only seen in background shots, with any closeups cut out, replaced with other footage, or obscured by editing. In some other TV appearances, her face is blurred or censored with a mosaic. Some publications still use her name, but in others her name and member number is erased entirely. However, she generally appears uncensored in photographed media and in music-related re-releases. The official reason for this is unknown, however fans speculate that she has an ongoing legal issue with Fuji Television, the copyright holder of Onyanko Club.
 * Both staff members and Onyanko Club members have stated that Ruriko was very good at memorizing and even improving on choreography routines, and spent a lot of effort helping members who were struggling with memorization.
 * She has the exact same birthday as fellow idol Minamino Yoko.
