In his mind life has been very uneventful for 16 year old Yuji Kizuato. At a glance, his high school life seems perfect due to the fact he receives attention from the opposite sex, is popular amongst his peers, and does well in school. However, often at times he is left questioning himself asking, is there more to life than this? What is his purpose? Just as he was searching to find something to be passionate about and devote his time to, that same night he stumbles upon another world. In this world, it is a place where magic, demi-humans, demons, and humans coexist. Shortly after, in this world he meets an Obeah woman (a witch) who tells him even though he's an outsider, in the future he will bring a great change to this world known as Agartha, but didn't specify if the change would be good or bad. Yuji takes this warning with a grain of salt, but does catch himself beginning to feel emotionally attached to the people and conflicts that go on in this world. As he continues his normal life in Japan, will his new found existence in this other world lead to prosperity or destruction?
