Oops, didn’t notice these videos at first. The official PV for Choucho’s “Authentic symphony”, the opening theme for the anime adaptation of Masairo-iro Symphony, is finally out! And not just that, but it’s on two different Youtube accounts. First off is the full PV in HD quality on the Lantis Youtube channel:
The PV is also contained in a segment she did for Kawaii Girl Japan. It seems to be about exposing female Japanese artists to a non-Japanese audience. Choucho answers some general questions about her background, the origin of her name, and her reason for uploading videos to Nico. The video is subbed in (bad) English, though it’s still comprehensible.
