Before he goes by Orphen, Kyrlancelo studies at the Tower of Fang in Childman's class, the group the school calls its most promising and everyone else treats as a hazard to the building. Azalie and Hertia are classmates, and between botched thefts to clean up, a monster loose near the neighbouring town and Azalie prying into Hertia's love life, almost nobody gets any studying done. This manga adapts the Pre-hen side stories from the light novels.
