Well, my favourite twins are the Hitachiin twins, but they're already posted. My अगला favourite are the Asaba twins, but there also posted. So I'll post my third favourite. Hope it counts! Ta-da!!!
Yuki and Kanade from कैन्डी Boy.They're often referred to as twins but they have different birthstones. They're the same age too but the lighter haired one is technically older x3
