The DLC adds four additional chapters to the end of the main game. While the main game resolves Lea's story, the DLC is primarily focused on two unanswered questions: what will happen to the Evotars in the future, and what is C'tron's connection to Sidwell?
- New Dungeon (Ku'lero Temple)
- New Area (Azure Archipelago)
- Extended Story (taking place after the Ending of the main game)
- New Regions (new Areas in Rhombus Square as well as the Homestedt Region accessible from Autumn's Rise)
- New quests, many of which reward Lea with Cross Points when solved.
- Ascended Equipment (stat bonuses increase as the wearer levels up)
After months negotiating with Instatainment, Lea and all other Evotars are officially approved to be a part of CrossWorlds. A New Home begins with Sergey and Satoshi re-examining her memory in the town hall of Homestedt, a small private town built next to Autumn's Rise to house Evotars including herself. Lea reconciles with all but three First Scholarly members; Apollo and Joern are currently on vacation, while C'tron is nowhere to be seen. Not long after, Sergey brings back Evotar Lukas whose name is changed to "Luke" after confronting his former self. The real/original Lukas then takes everyone on a short tour of Homestedt.
Sergey adds the three remaining question words to Lea's vocabulary: "Who," "What" and "Where." He then expresses hope to find a way to make the speech coding process easier.
Lea, Emilie, Luke, Raphael, Lin and Lukas take on a more challenging raid on Para Island the next day and defeat its boss with no outside interference. However, Luke is still bothered by his realization as a semi-copy of Lukas.
Sergey finds an Evotar copy of C'tron who, like Lea, initially has amnesia about his CrossWorlds experience. Lea guides him to memorable locations to restore his memory. In addition, after a few dreams, she and Sergey learn about his supposed involvement with Mr. Sidwell in Vermillion Wasteland which explains his absence from the First Scholar's 'final' raid in Chapter 10. Nevertheless, Evotar C'tron welcomes Lea to invite him to her party whenever he is available.
Lea and her friends eventually gain access to the expanded city of Rhombus Square which include an open PvP arena and a transporter to a newly-created area: the Azure Archipelago. Lea and her chosen party members explore the islands to find the Ancient Shade, the key needed to complete the Ku'lero Temple which is almost ready for release. Apollo challenges Lea to one final duel at Rhombus Square's PvP arena, now possessing all four elements.
Lea realizes that there is a connection between C'tron and Sidwell, and confronts C'tron. After Sergey intervenes, C'tron admits that he is an Evotar of Sidwell.
At Satoshi's new home in Homestedt the next day, Lea is first to hear the news that the true final dungeon has released. Shizuka successfully persuades her brother to take a break from coding and run the new dungeon together. Ku'lero Temple is accessed via the Ascension Temple in Sapphire Ridge which is greeted by all First Scholars and a huge crowd of anonymous in-universe players.
After completing the long dungeon, it is revealed that Instatainment is planning a sequel to CrossWorlds. Emilie and Lea go to meet C'tron, who left the dungeon early, and Emilie learns his identity. C'tron reveals that he still has missing memories of meeting someone in Vermillion Wasteland, so the trio convince Sergey to take them there one last time.
In Vermillion Wasteland, C'tron leads them to a hidden lab, where they find and battle an enemy based on Sidwell's avatar. C'tron finally remembers that he was already an Evotar during the main game, and that the current C'tron is a second Evotar created by the first to escape Vermillion Wasteland. Lea is given the final decision of whether C'tron will be allowed to remain in the game. Regardless of her choice, C'tron assists Sergey in locating Sidwell. During the closing scenes, the Evotars are shown to be given jobs within CrossWorlds, with Luke working as a tour guide and Lea working as a playtester alongside Shizuka.
