introduction
One day I was conducting a small-scale on-wall investigation activity before the 57th survey outside the wall. Ten or so survey members, including the main character (player), will search near the "old castle" in the direction of the headmaster. Without being informed of the purpose of the search, the hero who is from this area leads the troops and goes through deep fog. However, when the castle came through the last forest and near the immediate front, several giants appeared as if they were waiting for a party. In the turmoil caused by giants' raids, the ground collapses and the members of the investigation corps fall to the basement of the old castle. Although it is the hero who woke up in the lowest layer of the basement, the three-dimensional mobile device fails, and can not aim at the ground as it is. The main character searches for a mysterious underground facility by combining power with "Aibo" which could only join, and aims to escape from the dead ground.
