Aislin and Alexie are a pair of identical twins who reside in a hotel. Aislin's the older twin, while Alexie's the younger twin. They're quite naive and often ask residents at the hotel to play with them. However, they have no conscience, thus having no concept of good and bad. Aislin's seemingly a soft spoken and shy young girl. While not losing her childish impatience and enthusiasm, she often frowns and remains silent, while being thoughtful. Alexie's the complete opposite of Aislin.
