Story The series centers on the main character Jang-Gun and his friends along with their virtual reality avatars in the computer game world called "Lost Saga". When Jang-Gun logs on as a different character, he "Creates" an AI with a personality from the hacked disk he found when renewing his appearance for his once a year renewal process. Yureka is a flutter-brained, but advanced, AI with powerful stats and a real-life doppelganger. It is his turn to see just how deep his immersion in the virtual world goes. The following is a plot summary by volume: Volume One Many of the central characters (and their relationships to each other) are introduced in this volume, including Team Triple Threat, Lotto's family, Myriah, Aradon, the Lovely Angels, Row-the-Mighty, Miss Piri, and Capri. Oddly enough, Yureka does not make her debut until the second volume. Volume Two Jang-gun's birthday passes unheeded by his family, but he does find that he needs to renew his Lost Saga ID. When he goes to the Net Room to do so, he accidentally bumps into a girl who drops a card with the name 'Yureka' on it on her way out of the Room. Later that day, he accidentally logs on with the card, creating the impossibly strong but airheaded AI, Yureka, who is at once aware of her AI status and strength, but blissfully unaware of guile and trickery.

The next day he logs on under his own name, but is bewildered to encounter Yureka herself, who joins the Team after showcasing her strength the previous night. Volume Three Volume Three heralds the beginning of the first story arc, the Double Trouble Tournament. With riches and treasure as a promised prize, everyone in Lost Saga is dying to join. Lotto enters with Yureka at his side, and meets Rapha and John on his way to
