This is a man-made world, a place full of incredible power. When the disaster came, a group of 14 or 15-year-old children inadvertently but inevitably fell into this mysterious space. "Infinite Unknown" is the only unique TV animation among the movies I have watched recently. It tells the story of a group of children who live in a spaceship named "Levias" without adult leadership, betrayed by the outside world, and framed as terrorists for several months of escape. When people gather, a society will be formed; when people suffer a disaster, there will be riots and riots; when facing an unknown fate, there will be anxiety and fear. So when these things fall on a group of children, they are more intense. Deception, concealment, coercion, and violence cannot suppress the increasing restlessness in their hearts. When facing the powerful enemies outside, they can rely on Levias' magical power with peace of mind, but they are powerless when facing those faces that are as uneasy as themselves. In such a situation, I found how small my power is. It is not enough to work hard. I can no longer suppress my dissatisfaction and smile at people like before. Everyone has become more sensitive, like a string that is stretched too tight. As long as there is a gust of wind, it will be broken, and the sound is deafening. The difference from ordinary animation is that "Infinite Unknown" is not just a hot-blooded comic about machinery and war. In this film, we see more of the performance of every ordinary person when despair fills the entire Levias. And the director used a more special form of expression, that is, the mysterious girl who appeared in Levias from beginning to end. A girl who began to feel like Rei, a girl who was so simple that she was almost blank, a girl who had never come into contact with outsiders and did not understand the human heart at all. Walking around in this cabin as if there was no one, feeling the fear, sadness and despair of no one. So this girl who started with a blank face became able to laugh, cry, feel sad, get angry, and then become stronger. Why is it like this? ! Why? ! So painful! So sad! But I don't want to die! ! I want to live! ! Therefore, Levias has a stronger power, so he can survive every time because his belief in wanting to live transcends all emotions and obstacles. Levias is a mysterious world, Levias is a product of human technology, Levias is a girl as white as paper, Levias is infinitely unknown.
