Lost in Stray Pair! Hime and Seiji's Great Adventure!

Whilst on the train back home, Hime and Seiji stop by a station to get a drink. However, when the vending machine ends up giving them too many prize drinks in a row, the train departs with Hime's Pretty Change Mirror and Seiji's Cure Line phone still on it. As the two leave the station in search of a payphone, Hime is troubled by a sprained ankle, so Seiji treats it and offers to carry her. The pair are soon confronted by Hosshiiwa and her Delinquent Saiark and Choiarks, with Seiji stepping up to defend Hime from the Choiarks before Megumi and the others arrive to help. Angered by Hosshiiwa's poor treatment of Seiji, Hime, who regains her Pretty Change Mirror, gains the strength to defeat the Saiark by herself. As the group make their way back home, Hime fears that she herself has developed a crush on Seiji.
