She modeled for TOKYO GIRLS COLLECTION in 2011 and 2012; in 2013 she modeled for KANSAI COLLECTION.
On June 5, with the reformulation of the E-girls project as E.G.family, she announced to be leaving E-girls after the E-girls LIVE 2017 ~E.G.EVOLUTION~ concerts in July due to her busy schedule. She would be dedicating herself to Flower, ShuuKaRen and her model activities.
On October 22, Fujii posted a message on E.G.family mobile reporting that she got diagnosed with cervical spinal disc herniation and that she would halt her activities for a while to recover. Fujii started experiencing symptoms of cervical spinal disc herniation 3 years ago and since the E-girls LIVE 2017 ~E.G.EVOLUTION~ concerts in July she has been feeling unable to perform like she hoped to. After consulting a doctor she got diagnosed with herniation affecting the fourth and fifth vertebrae on her neck and she is putting effort on receiving treatment for it. After discussing with the Flower members and staff and since she is unable to serve satisfactory performances with her current state, Fujii would be taking a rest to recover.
On December 31, it was announced that Fujii has decided to graduate from Flower and ShuuKaRen and retire from the entertainment industry due to the symptoms of the cervical spinal disc herniation, that she got diagnosed with in October, becoming more severe. She would be focusing on studying art, photography, and fashion following her retirement.
