So, what do you think about this anime. I probably need to tell something about it so: The main characters are Ai (boy) and Yu (girl), two children. Their 'adventure' starts when their parents have gone missing. They decice to go to outer world to which leads a strange black pillar that appeared ten years ago at the two giant beasts battlefield. The only safe way to get there is by the train that appears on the station at 0:13:13. Inside of eat, they meet an about 20-years old girl who introduces herself as Lisa. Togeter the three go into FF-like world. And what is next? Go to youtube and watch, duh. ==
