Secret Apostrophe - S1.E7

Naoya travels to the human world in order to replenish Astarotte's magic so that she can return. However, Astarotte is still mad at him and tries to lock him out of his house, though this ultimately fails. After making up with her, Naoya kisses Astarotte on her forehead, allowing her to regain her magic and return to the demon world. As Naoya takes Astarotte to an amusement park as way of apology, Elika decides to take Asuha with her to the same park. To test her alleged 'adulthood', Elika suggests Astarotte go inside a haunted house, where she becomes so scared that she wets herself. As she becomes upset about it, Naoya reveals he didn't stop wetting the bed until he was 12. Upon returning home, they find Ingrid has moved her tower closer to the castle and become shocked when Ingrid suddenly kisses Naoya on the lips.
