The magazine should be called Kairakuten Feels not Beast... I would say she needs her masks as they protect her (fragile) inner self from the outer world and if she would lay down all her masks she would break down. My guess is that she has such a sad past that hearing would make us cry like little girls...
You see, people,(and I think) especially woman wear many varying masks towards other people.
Seeing through it is one thing, but accepting it for what it is, that perhaps, those masks are also part of who she is, would be a different, much more difficult thing to do. If you could learn to love even that part of her, well, maybe you have a chance.
I'd certainly like to see what he does in the future, so a sequel would definitely be nice...
