Season 1

There is a legend that says if you make a wish under the clock tower at midnight during a full moon, time will be turned back. Koyuki, who lost her brother in an accident, meets Victor and Kiri one day in the graveyard. What secrets do they hold?

A pure white Horologue appears in Celavie, and its huge size implies that it must have devoured thousands of years' worth of time. Victo and Kiri face the brunt of its immensely powerful attacks until they're saved by Mina, a girl who can control wind.

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.

Victo 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.

While flying to Couljours, Victo's party encounters a strange man with a ring that commands a Horologue. Can four Chronos Rulers together defeat such a powerful foe mid-flight?

The party has arrived in Couljours. Victor feels nostalgic as he observes a town that looks just the way he remembers it, until he encounters visions from his past.

Kiri, Mina, and Blaze head into the forest on the outskirts of town in pursuit of a huge snake-shaped Horologue. Its behaviour is not like that of other Horologues, leading Kiri to believe it has something to do with what's happening in Couljours.

As Kiri's group heads deeper into the forest, they come across a wall of time. As they search for the truth behind the reversed flow of time in Couljours, they're attacked by Fujibayashi and Raiko.

Mina and Blaze have engaged in an intense battle with Fujimoto and Raiko. Meanwhile, Kiri rushed to Victor's aid in the nick of time as he was facing his long-standing adversary, Aiks.

Victor resolves to battle Aiks, even if it means losing his mother for a second time. Kiri, Mina and Blaze arrive and join forces with him. But Aiks has many strange powers not yet revealed, and none of the Chronos Rulers have glimpsed his true form.

Time that has passed can never return. But even if everything in the past is lost, there is still hope for the future.
