Feathers is an underground idol duo made up of two twins, Miu and Yu, that was called to perform at the Marukane Department Store Live Event.
At some point in their lives, Miu and Yu decided to work together to form an idol group, which they named "Feathers." Before the events of Vigilante - My Hero Academia: Illegals, it's noted that Feathers have performed at a number of smaller venues.
