Btw. It overwhelming information now. 7 days left, good time to reconsider and finished Mio ark. Also I expect beginning of the Lyrica arc. I'm afraid Shiro could not take easy that she is technically Destroyer of the world. Knowing her she should try her best to become Creator, not Destroyer. Maybe she voluntarily seal her destruction ability to concentrate on creation. Also I could not find the reason for her vendetta to Aria and Aekari. It just become useless because Shiro is knowing motive behind this. It defenetly doesn't make them friends but suppose to shift Shiro's focus to another direction.
And doesn't Shiro has a greate dislike for Masochist but if you look at it she really could be worshipped by the Masochist like a godess. For one is that she has a really great body that could take great amount of damage. But also that she could act like a great Sadist to the Masochist. So I would find it really funny if she ever god A title saying that she has become a god for Masochist people
