I'll just same some things that look alike. The 1st thing that caught my eye was they both have similar uniforms. (Maybe like their in the same school but ones older than the other one?) 2nd thing is their poses look the same. 3rd thing is like where their looking at its like the same spot. 4th thing is their skin color is the same. Heres some things that are different. 1st thing is that their colors are different. 2nd thing is a bit about their pose Kugie looks like shes looking down at someone most likely Kanna. While Sara is just standing. 3rd thing is that the tie for the uniform is different Kugie has a bow and Sara has a tie. 4th thing that I noticed was Kugie has a clip and some headband thing? And lastly their hair is different. Ok I'm done this took a while to type.
