Yina and Yani are twins. My OC twins are these two. They show two parts of my split personality. Yina on the left is tall like her father Gaster but has Sans's smile. She represents my grown side. My grown side just shows how mature and adult like I act which is how I act most of the time. And Yani, she is my childish side. She keeps me giggling and smiling even though I am sad. She is rarely seen when nothing is worth smiling about is around. Yina and Yani have their arguments because they are completely different. Nothing about them is the same other than their brilliance. They are just like a Yin Yang symbol.
Have a nice night!~ Amura
