She is known for having long, black hair, with a thick full fringe which covers her short, brightly coloured eyebrows. She is also the only member that wears glasses.
Previously a member of the idol group →EXIT← by the name Naru Ramenski, however I have not been able to find any other information about her in the group, or any live footage, therefore she may have not debuted.
She originally auditioned for the reformed BiS. On being unsuccessful she was placed into SiS before being merged with GANG PARADE. She considers GANG PARADE as her reason to live.
During the WACK 2018 New Year’s live broadcast, she was randomly selected from the non-ranking WACK members to have a solo debut, under WACK’s indie label WcDONALD Records.
