Engaged to the Unidentified

Hakuya is troubled over what gift he should get for Kobeni to make up for White Day. Meanwhile, Mashiro is almost spotted using her powers by Niko, who becomes determined to investigate the existence of a 'flying humanoid'. Later, Mashiro suggests that Kobeni and Hakuya go on a date, though Kobeni turns it into an outing with Mashiro. On the way home, Kobeni discovers Hakuya has a scar over his right eye, quickly coming to the conclusion that he got it from saving her. The next morning, after Hakuya and Mashiro receive another letter from their clan, Kobeni discovers they have disappeared, along with their belongings.
