Grow into One (stylized as grow into one) is the second studio album released by Japanese pop and R&B singer Koda Kumi, released on March 19, 2003. It barely peaked in the Top 10 on Oricon, coming it at #8, and charted for 43 weeks. The album also contained, at the time, one of her best-selling singles, "Real Emotion/1000 no Kotoba". Combined with the singles, the album has sold over half a million copies in Japan. The album featured rap duo Clench & Blistah and urban contemporary singer and producer Lisa, who had been featured on Kumi's single "Maze", after having just split from her founded hip-hop group M-Flo. Background and composition Grow into One was released one year after her debut album Affection. The album was predominantly R&B with the only pop songs being those she performed for Final Fantasy X-2, which was released on the PlayStation 2 in 2003. Those songs were "real Emotion" and "1000 no Kotoba". The only other pop song was "To Be One", which was used in some of the online advertising for Final Fantasy X-2.
