First, who is Ren? Half of the people from the Kou Empire have Ren in their name. And people probably treated Hakuryuu killing Gyokuen as a bad thing because she was the empress of the Kou Empire and it's probably also just shock that he killed her. And I don't know if you read it all but Gyokuen is possessed by Arba and she killed Hakuryuu's dad and brothers. So he has a grudge against her and wants to kill her. And if you haven't read it all it turns out that Arba just needs to posses someone that she gave birth to. So after Hakuryuu kills her she possesses Hakuei which is Hakuryuu's sister. The thing about Sinbad is complicated because he wants to make the world a better place but doing that, he rewrites the rukh and so many other things that seem pretty evil in Aladdin's point of view. He also manipulates a lot of people to help Sindria and the world.
I put the story on hold when i got to the sinbad becomes the villain part (uwu i luv u purple daddy T^T) but im back now that the story is complete and im so confused during this reread?? Im not even a where i left off before yet but like what is the issue between ren, hakuryuu, and their mother??(i dont think i spelled any names right)
1) What grudge does Hakuryuyruy have against Ren? i dont undersand thier backstory
2) And didnt hakuryuu kill his mom the leader of the bad people? why does it seem like everyone is treating that like its a bad thing? liek i know he didnt use the best way of doing it but like?? they defeated their main enemy right, goal accomplished??
