This is from the pink series sold at Threeppy (3COINS) during the Setsubun festival in 2025. It's a bloomer pants and a set of oni (demon) horn hair ties. Last year, I paired it with a black top and black tights, and it was very cute. The hair ties are new and unopened. The bloomer pants have been worn about twice. These are items that a child has worn. Please refrain from purchasing if you are looking for a perfect item.
