Koyuki a perdu son frère. Emplie de regrets et tenaillée par le désir de le revoir, elle devient une cible parfaite pour les Horas, des êtres qui se nourrissent du désespoir des êtres humains.
Une fois arrivés à Serabi, ville des casinos, notre duo tombe sur le Hora qui a marqué Victo à tout jamais…
Mina leads Victo and Kiri to the headquarters of Chronos, a secret organization founded to battle Horologues. As he searches for information on his own past within the facility, Victo discovers a record of his work within the organization.
Victor ends up in a battle with Aisrehdar, the leader of Chronos that rules over all creation, but the difference in their strength is incomparable. Mina catches up to them and witnesses something unbelievable...
Victor and Aisrehdar battle one-on-one for the possession of UNIQUE, the original Oath of Time. What tricks will the expert gambler attempt to use on the child of a god? Meanwhile, Kiri and Blaze battle using the opposing forces of water and fire.
Having completed Aisrehdar's tests, Victo and Kiri's lives briefly return to relative calm.They attempt to decipher a mysterious coded language in their efforts to find the records of Victo's past work with Chronos.
En route to Couljours on a jet, Victo's party encounters a strange man who bears a deep regret and a ring that commands a Horologue. Can even four Chronos Rulers together defeat such a powerful foe while trapped so high in the air?
The party has arrived in Couljours. Victor feels nostalgic as he observes a town that looks just the way he remembers it, but then he encounters his parents, who were supposed to be dead, and his younger self.
Kiri, Mina, and Blaze head into the forest on the outskirts of town in pursuit of a huge snake-shaped Horologue. Its behavior is not like that of other Horologues, leading Kiri to believe it has something to do with what's happening in Couljours.
