A forbidden elite academy where the strongest duelists gather.
About
Countless dueling schools exist in this world, but only one is known to produce the "Ultimate Duelists." Its name is 「Eclipse Duel Academy」 This is no mere school. It is a super-elite institution watched by the entire world—from nations and corporations to military organizations and professional dueling leagues. Students are divided into ranks and exclusive classes based on their skills. The higher the class, the more powerful cards, privileges, and private facilities they are granted. At the center of it all was the new MYTHIC CLASS duelist, 「Kaion Akris.」 He masters all summoning methods freely, displaying plays that even the dueling system cannot predict. Students admired him, professors were wary of him, and some called him the "Being Outside the Rules." Then one day, the forbidden system 「ECLIPSE」, sealed in the deepest depths of the academy, begins to react.
