The story of two girls who have been together in all things since they were children. Yukari has always been the type who wanted to do everything her best friend Haru did. It's unclear whether she acts out of envy, love, or madness, but her feelings become a darkness that leads to a tragic fate...
We'll do everything together, 
just like always.
سنقوم بكلّ شيءٍ سويًّا، كما العادة
Machen wir alles
gemeinsam, wie immer.
Sigamos haciendo todo juntas.
Sigamos haciendo todo juntas.
À présent, on fera tout pareil…
Comme deux gouttes d’eau.
Faremo tutto insieme, come sempre.
Faremos tudo sempre 
juntas como de praxe.
