Young girl Rain, who became a holy knight of the kingdom at a young age, is entrusted with the investigation of an incident happening in the distant town of Hakudeti
by her lover and leader of the holy knights, Jazz. The incident involves an increase in criminals in the once peaceful Hakudeti, an overflow of monsters in the vicinity,
and the appearance of a mysterious dungeon. Though Rain appears to be a cold-hearted warrior, deep down she longs to be with her beloved Jazz. Suppressing her
hidden desires, she sets off on a journey from the capital. Little does she know that awaiting her there is a trap, filled with swirling desires of her enemies.
