Chihayafuru x ZIP! Collaboration Videos
Anyway, just checked and these clips have been stuck in QC since December 2017. We were supposed to do all the Blu-Ray extras of Chihayafuru trilogy, but I changed my mind as times are evolving and the only permanent thing is change.
These clips were originally released as beta versions at the now dead yasub.com last December 2017. But they were not typesetted or anything as the dead site only can handle srt subtitles.
