The story was kinda cute until the little boy says, "I'm a man, too. I'm going to protect you !". No child, you are like 5 years old, YOU need protection. Virilism since childhood. He could have just said, "I don't have anyone and I really like you. I'm not letting them take you." or just "I'm scared. Save me !". It's a child, why do they have to enforce the fact that the boy or like they said it "A MAN" and is going to save the monster with a female form. This is stupid.
This could have talked about a lot of things with this, the work condition of prostitute, child abuse (Lilia look like a 12 years old girl), the men who paid for sex and don't care about the situation of the prostitute and the fact they don't care about who they sleep with (again Lilia looks like a little girl and not a single man care about that at least they didn't show it, so all men in this work deserve to die, f*cking pedophile). All the PINK DISTRICT, don't add anything about the story. If Lilia only eats human to live, they are literally living people who don't have a house and sleeping outdoor. Becoming a prostitute to eat people is kinda stupid and useless.
But maybe I didn't get the second reading behind all the story. But for now it's just a story about 'A MAN' who is going to give some love to a female monster little girl prostitute who was abuse by A MAN.
