The PV for Japanese singer and voice actress (seiyu) Nana Mizuki's latest single "Scarlet Knight" has been released. Nana Mizuki wrote the lyrics to the song herself with arrangement done by Hitoshi Fujima (Elements Garden). The single will be used as the opening theme for the anime series Dog Days. Scarlet Knight will also be used as the ending theme for TV Asahi's Onegai! Ranking in April. This is her 23rd single and will be paired with "High-Stepper" and will be released on the 13th of April 2011.
The video takes place in what seems to be a gothic looking church with a huge bell and lots of nuns in the traditional outfit. Nana Mizuki herself alternates between a white nun outfit and a red dress. There is also a scene where she is holding onto a soldier's helmet and in thought which could be a clue to the storyline of the PV. Towards the end she is seen posing with a sword and shield in her red dress thus the link back to the title "Scarlet Knight".
