Ariene is a character of the day who appeared in Hi Ho Silver...Away!. She lives in Kasado City on Silver Rock Isle.

She appeared to be an expert on Silver Wings, as she could tell when a salesman was trying to sell Ash and his friends a fake one. Realizing they wanted to learn more about Silver Wings, Ariene took them to her friend Jenaro, who made the Silver Wings. When they arrived, they found Jenaro unconscious with his Sandslash on the floor. Ariene didn't know it, but he was planning a surprise for her.

The next day, Team Rocket tried to steal all of the Silver Wings on Silver Rock Isle. Ariene thought Jenaro was acting very strangely when it seemed like he wanted to retrieve something Team Rocket had stolen. As it turned out, Jenaro loved Ariene very much, and wanted to marry her. After retrieving his newly crafted Silver Wing from Team Rocket, he gave it to Ariene to replace her old, worn out one. She accepted Jenaro's marriage proposal, much to his relief.
