Yonhyakunijuu Renpai Girl is a single-episode promotional video from 2013 made for Naruto Kiriyama's light novel of the same name, with illustrations by Nanamomo Rio. The title translates roughly as being turned down by 420 girls in a row, which sets up a romantic comedy about a record-breaking streak of rejection. Enterbrain commissioned the video after Kiriyama took the Grand Prize at the publisher's 14th Entertainment Awards in its light novel category.
