Durarara!!: Orihara Mairu and Orihara Kururi

Twin sisters of Orihara Izaya, Mairu and Kururi are complete opposites of one another. Mairu, the younger twin, is an outgoing, trouble-maker like her brother, while Kururi is shy and soft spoken. Kururi is often bullied because of her sister’s reputation, but both sisters have their ways in responding to threats effectively. The twins are fans of Izaya’s friend, Heiwajima Kasuka.
So cute! And could they be twins or sisters in real life, I wonder?
