murano_sayaka_(downer-kei_gyaru)
Murano Sayaka, depicted as a low-energy gyaru. Often paired with an introverted_Kaho.
This characterization of her spawned from Twitter at around November 27, 2024, with the help of soora0202, Hosino Mukou, and several others' ramblings.
She is usually depicted in a generic school uniform with a white collared shirt, a loose black bowtie, and a brown cardigan, but other variations may also exist.
