Anos and the first-year students visit Zehenburg under the guise of an expeditionary examination. Anos's goal is to find his former right-hand man, Shin Reglia, who left a message for him, "Wait for me in the Spirit Forest Aharthern." On the way to the forest, Anos meets an information broker, Lena. Together with her, who is also heading to Aharthern, the group proceeds into the forest's depths.
