Japanese singer and voice actress Nana Mizuki has released the music video for her 23rd single “Scarlet Knight“. The new single, which was written by Mizuki, will be released officially on April 13, 2011 along with her 24th “Pop Master“. “Scarlet Knight“, like most of her previous songs, is the opening theme for TV anime “Dog Days“. The music video is sincerely dramatic and somewhat dark, featuring women dressed as nuns playing violins. It’s like Nana’s playing on the spiritual side. The singer is dressed in a red dress, which coincides with the meaning of Scarlet, the color red. Without me going on and on, check out the music video below and tell us what you think.
