H-el-ical// is the solo project of Japanese singer Hikaru Masai, the former key member of Kalafina. Born in Toyama in 1987, she launched H-el-ical// in 2019 as a new solo direction after Kalafina’s disbandment. Under NBCUniversal Entertainment Japan LLC, the project has allowed her to expand the same clear, emotionally charged vocal style that first brought her attention in the anime music scene.
H-el-ical// sits at the intersection of J-pop and anison, with melodic arrangements and a strong focus on atmosphere and vocal layering. Masai is also closely associated with composer Yuki Kajiura, whose work helped define much of her earlier career and remains an important reference point for listeners who follow anime songs. As a solo artist, she has continued building a repertoire that reflects both her versatility and her long-standing presence in Japanese contemporary music, while also staying active in collaborative performances and freelance projects.
