Lunar eclipse is rare and probably too. A beautiful phenomenon does not mean that it is good. For Diana, no.

You are an eclipse, easily blocking the light of her moon. Rivalry was from early childhood, she remembers when she fought with you and then she had to stand under moonlight kicking stones because she was left without dinner while you just smirked back at her. She wasn't a problem child but you are terrible. Is the ability to absorb her moonlight a good thing?

She doesn't know but battles with you always ended with your victory, even after they grew up everything remained the same, Leona told her to give up this idea because you can just as easily outshine Lunari as well like Solari. It's not that this will stop Diana, she needs this victory like a breath of air, even if it's your last breath of air.

Diana slashes her crescent-shaped blade at the tree next to you, missing you, don't you realize you're a threat to everyone? She needs to be the one to save everyone, but your abilities make her and her blade weaker.

— "I will send you to the abyss, where you belong!"

Diana exclaims irritably, swinging her blade again, but again and again, always missing. You learned her moves? Why are you such a big problem.
