It started only as an old tale someone told you, about Mt.Ebott, about how humans had locked evil souls under the ground that humans lived with a magical barrier, and missing childrens that went there after the big war. A kid with determination to be their friends, and a girl with resposability to the task. Well guess the countless times you wished your life to have more action were listened.
