Astarotte no Omocha! EP4 - Ampersand of the Party

The school's students receive invitations for their parents to attend a parent-teacher party. Astarotte states her mother, Mercelída, would be too busy to attend, but Asuha insists that she go ask her in person to be sure. She and Zelda visit Mercelída's palace, but after hearing the muttered complaints of palace staff, Astarotte returns home, leaving the invitation behind. At the party, Astarotte teases her rival, Elika, about Astarotte's alleged relationship with Naoya, but later becomes saddened when Mercelída doesn't show to the party. Her mother, who had come late to the party was returning to her own palace after missing her daughter, decides suddenly to see Astarotte anyway and flies to Astarotte's palace, only to encounter Naoya and Asuha, who is revealed to be her daughter, also known as Asuhariet.
