A Short Film and the Sixth Hero (S02E07)

After completing the fifth quest, Yotsuya is back in his hometown when a woman named Glenda pays him a visit. She knows about the other world he's been to, and she claims to know at least three other people who have been there. Glenda hopes to get in touch with these parallel world explorers, but she's had no luck contacting them through social media. So she decides to produce a video of Yotsuya and his fellow party members that only people who have been to the other world would understand. (Crunchyroll)
