I like the 3 brotherlike figures, so cute and protective~ Though the idea of souls in original world being hunted by divine beings kinda feel dark and scary... it's possible that the indicated concept is that the souls are basically food/energy to the divine beings to keep their divinity, not that the divine beings are benevolent or malevolent but it's just part of the nature/ecosystem to them, which isn't a new concept in fantasy stories.
Relevant topic, Personal rant: This is why I personally feel that if there is god(s) in reality, whether they are benevolent or malevolent in nature is not up to us to decide because we're merely humans and aren't actually capable to understand divinity, which is why those religious fanatics/overzealous followers who behave like they understand/know what the god(s) want and act like they are the chosen ones and decide what/who is right or wrong based on their personal religious views (disregarding that there are other religions in the world and people who don't follow the same religions) to the point that some of them can be very proactively and aggressively judgmental, hateful and violent (which I actually noticed how some people I personally know had changed their personality a lot after newly converted/joining a religious organization, as if they are desperate to prove their loyalty to their new religion or something), is just really scary and insane to me, and that has really caused me to feel greatly anxious, and guarded whenever some people bring up their religious views and preaching in chatting, aside from feeling upset and disappointed that some people become weird and judgmental after they got a new faith (like they suddenly behave with the mentality of "people like you, who are not of the same religion as me, do not sit well with me/us, unless you're gonna listen to my preaching and agree with me, otherwise you're inferior beings and deserve less than me/us and should be judged". IDK, maybe I happened to come across more such kind of people in my life for some reason, and that really affects my trust in people's motives/sincerity nowadays. 😔 Man, this pandemic and isolation really bring out a lot of emotions and opinions in me triggered by random topics sigh.
