Dragon Emperor Accor, the final ruler of the Baikal Dynasty. The Emperor who had turned into a Tyrant after a fateful incident, was sealed by the Grand Master Knights.

The Bailkal Empire was then divided into 7 kingdoms and the past became nothing but legends along with the relics containing Accor’s power. However, those who sought out this power came forth, leading to the assassination of the Emperor of Lenombe as well as the theft of Exestruk.

The story of Exos Heroes starts with a treasure hunter named Zeon, who gets mixed up in these incidents.

After some time, just when the people of Exos thought they had overcome Emperor Accor’s tyranny, a mysterious incident known as the Missing Link, occured and Exos faced another threat. Countless multiverses connected to Exos B218 and DESPERADO B218, who are in charge of managing universe B218, began mobilizing to resolve this threat.

Contradictory to the urgency of the situation, DESPERADO B218’s base of operations is a quaint bar. It is not marked on any map nor does anyone know how to reach its location, but new agents are recruited and teams are dispatched to find the truth behind the Missing Link.

One of those teams will be yours.
