There is no reason for a promotional video to look this good, but it does! It displays the events in Asagao to Kase-san in a amv format with visuals that are very pleasing to look at and the song is nice. It effectively shows the daily lives of the two heroines without spoiling a single thing to get the viewer wanting to find out more about them through the manga. Even though it was mainly created to promote the manga, you may want to watch the OVA that had came out for recently if this had interested you as it is basically a full version ofthis.
