The mood whiplash from music video just like an internet algorithm serving up whatever; was something else.
my theory crafting
So Akane has wrong information about that body wasn't in fact Aqua's father / murderer. A witch(?) (She totally looks like a witch) has manipulated Rudy to begin searching for her own revenge on the manipulator . Akane gaslights Ruby that Aqua wasn't searching for his revenge the whole time.
The viewers know who is the manipulator. Why does some random girl has star eyes?! Why the Murderer has star eyes? WHAT DO THEY MEAN?!!1111!!!???!?!
Why Aqua lost his eye!?
Ughhhh... That face...
Can't wait for the next season. I have enjoyed my time watching growth of Aqua, Akane and Kana on stage.
