Since gaining popularity as a KERA (whose pages Kyary Pamyu Pamyu has also graced) reader model, Luna Haruna has been chosen to perform the end song for the second season of Fate/zero as her major singing debut. Partnered with her is composer/producer Yuki Kajiura, so if there are fans of Kalafina in the house (Kara no Kyoukai, Black Butler, Madoka Magica), it might be time to make some noise.

By the way, Luna Haruna was a finalist in the 4th Animax Anime Song Grand Prix.
Luna Haruna is still on active duty as a punk/loli reader model in KERA, but she can be seen in the latest RisuAni (on sale January 25th in Japan). Besides the pictures and interview with Luna herself, one of the editors at KERA describes her as, "a younger sister character who knows how to dress well in diverse fashions." Kajiura also praises her voice for its sense of presence. The RisuAni issue comes with a CD of an original song, "Binetsu no Tsuki" ("Slightly Feverish Moon").
You can already check out a sample of "Binetsu no Tsuki" on Luna Haruna's official website. Are you ready to hear her at the end of Fate/zero?
