Her first significant pivot came in 2009 when she joined the multimedia franchise Love Live! as Eli Ayase. At the time, Love Live! was a modest project with no guarantee of success. Nanjo, then 25, was one of the older members of the nine-person group μ's. This age gap, initially a source of anxiety for her, eventually became her strength. While younger cast members embodied raw energy, Nanjo brought a mature, classical elegance to Eli—a Russian-Japanese student council president with a hidden soft side.
She also found massive success as the vocalist for the electronic project fripSide . Taking over from nao in 2009, Nanjo became the face of fripSide, blasting through the speakers of every anime club with the Raildex franchise themes: "Only My Railgun," "LEVEL5 -judgelight-," and "sister's noise."
These songs require a vocal range and speed that is punishing. "Only My Railgun," with its rapid-fire syllables and sustained high notes, is infamous in karaoke circles as a "song killer." Yet Nanjo performed it live hundreds of times, rarely missing a beat, despite her leg preventing her from bouncing on stage to keep rhythm. Beyond the microphone, Nanjo is an avid writer. She pens a long-running column and has released several essay collections. Her writing is introspective, often discussing her love of cats, her struggles with social anxiety, and her obsession with PC gaming. In a 2018 interview, she famously detailed her custom-built gaming rig, much to the delight of her tech-savvy fanbase. This "otaku" authenticity—the fact that she genuinely plays Final Fantasy XIV for 10 hours straight on a day off—erodes the artificial barrier between celebrity and fan. Legacy and the "Second Act" As of 2024, Nanjo Ichika is approaching her 40s—a dangerous age for female idols, but a comfortable one for vocalists. Following the retirement of μ's from active performance, she has focused on her solo work and fripSide (which concluded its "phase 2" in 2022).
Fans would watch her walk on stage with a cane, only to toss it aside for the chorus. During the final μ's live concert in 2016 ("μ's Final LoveLive!"), her determination was palpable. Critics noted that while she couldn't jump as high as her counterparts, her vocal stability never wavered. In an industry obsessed with "perfection," Nanjo’s struggle made her relatable. She proved that an idol could be physically vulnerable yet spiritually unbreakable. Parallel to her idol work, Nanjo has maintained a robust solo career under the NBCUniversal Entertainment label. Debuting in 2012 with the mini-album カタルモザイク (Kataru Mosaic), her solo work diverges sharply from the pop-sugar of Love Live! . Her sound is rooted in electronic rock, synth-pop, and driving guitar riffs.
Her recent work has matured. Tracks like "Kira Kira no Hana" from the Hachigatsu no Cinderella Nine soundtrack show a softer, wiser artist. She has also taken on more mature voice roles, moving away from high school girls to mothers and mentors.
Her breakthrough solo single came with "Kimi ga Emu Yuugure" (2013), but it was "Magnet" and later "Zero Ichi Kyou" (01期) that defined her solo aesthetic. Unlike many voice actors who sing in a high-pitched "character voice," Nanjo sings in her natural, lower tenor. The result is a sound reminiscent of J-Rock bands of the early 2000s—melancholic, heavy, and distinctly urban.
