Spotlight #25: Ayane and Mayane

Ayane and Mayane Rodriguez, both age 20. Born to a Japanese mother and Brazilian father, the two spent their lives growing up in Brazil. While Ayane is mischievous, Mayane is strict and serious. Ayane's more physically fit, while Mayane's smarter. In short, the twins are opposites despite their identical looks, though thanks to Ayane's abs and muscles, it's easier to tell her apart from Mayane. 

The two are both average chess players, but Mayane tries to take things more seriously. As such, it's common for Ayane to mess with her sister, often by impersonating her in order to give her more headaches.
