TOHO began streaming the first promotional video on Tuesday for the television anime adaptation of Matcha Hazuki's Isshūkan Friends. (One-Week Friends) manga.

In the video, the character Yūki narrates: "We do this over again each week. Many times. Many, many times. That girl had nothing to do with other people. She was always alone. I thought, I just want to be friends with this girl." He then says to Kaori, "Please be my friend." Then Kaori responds: "It's impossible for me to make friends. It's definitely impossible. My memories of my friends disappear in a week..." Yūki then says, "Even so, I want to be your friend. Over and over again."
