Music video directed by Rina Mitsuzumi for the song Summer Slack by ZUTOMAYO. The music video is prominently made up of scenes not seen in the anime feature, with the familiar Nira-chan (from ZUTOMAYO's music videos) being in the world of Drifting Home.

Note: The song featured in this music video was originally used as an insert song in the anime Ame wo Tsugeru Hyouryuu Danchi.
