As Seisa reminisces about an old upperclassman, Eruna takes an interest in Otone, who appears to be just as weird as she is. Meanwhile, the Drama Club, noticing Asuhi feeling down about his defeat, decide to hold a party to cheer him up. After Eruna invites everyone to come along, Bimii, exhausted from escorting Eruna, mixes up an invitation he was supposed to give Asuhi with a message about a change in venue he was supposed to give Eruna. As such, Eruna misinterprates Asuhi's invitation as a letter of challenge and almost ends up initiating a match against Sadamatsu before Asuhi shows up. While waiting for the rain to stop so they can have a rooftop party, Asuhi explains how he came to love stars, after which Seisa uses her ability to put a stop to the rain and give Asuhi his starry-skied party.
