Lexis. The set of all words. Have a nice watching.

Since some viewers have found it hard to understand the animation, I'll try to explain what it is about. The story itself is trying to say that every person (every creature) is a creator, author, artist, and god of everything they make in their own lives, all the changes and creations. Every author needs an instrument to realize and create his idea, of course, but there's always some moment or boiling point where things get out of control because of the author's personal ideas. Sometimes, the idea destroys the creator.
