What are roles for moony and sunny? Are they enemy or friends?

Enemies

Oh thanks, so what happen between both red and blue hair? I'm kindof confused of each charater's purpose haha

I think that they love each other but blue head has obssesion on his point (red head) thats why he was smiling at the last part. Or since moony is the bad one it changed him. We will se

Thabk you! (≧∀≦)

Np!
