Welcome to Arcadia! The world’s most plausible virtual reality game created by three major conglomerates, Ajin Electrons, Sillicoff Industries, and Argos Corporation. Join Jaeyeong, a legendary gamer who goes by the ID Dex, on a chaotic adventure as he hops in the capsule Dreamer to access the fantasy world of Arcadia! Are you ready?

In Academy City, magic and science coexist in an unwavering power struggle. Toma Kamijo, an academically-challenged student in Academy City, wields the power of the Imagine Breaker in his right hand, which allows him to completely negate all supernatural powers – as well as his own luck. When he happens upon a mysterious nun named Index, whose mind has been implanted with the Index Librorum Prohibitorum – 103,000 ancient texts banned by the Church – Toma’s luck is about to be pushed to its limits when he finds himself in the middle of a war he never expected!

Calling the old god’s mage, the knight who inherits the bloodline, looking forward to the glory of yesterday;

The noise of steam engines and the roar of cannons indicate the direction of the future;

An Sen, who was living in this world, embarked on a road that had never been imagined;

In the ashes of the old world…he shall be crowned king!
