11. Bölüm: Yuki ve Takuya Lost'a girerken Taiyou, Daichi'nin dijital formuyla yüzleşir.

En route on Takuya's motorbike to the Lost area; Yuki and Takuya spot Suzuna from the Lacuna Chemical Laboratory talking with some police officers. It's suspected that she and Taiyou plan on going to Lost as well. Elsewhere, Yumiko and Kouta are on reconnaissance watching over a Lacuna antenna that'll be hacked by Eiji. A flashback reveals that the antenna will help maintain the sanity of Takuya and Yuki when they're in Lost. While infiltrating, Lacuna Kouta and Yumiko run into two cloaked guards who try to stop them, but Yuuji and Keigo intervene allowing them to progress. Back to Yuki and Takuya who reach a roadblock, they get help from the Phantom Thief Brigade and Yoshiaki who gives them some communication devices. Eventually, the two find Suzuna who's near-death after trying to betray Taiyou. Before she dies, Suzuna confesses her regrets for being a part of Yuki's torment. With the help of Kana, Geek is able to hack into the antenna allowing Takuya and Yuki to be able to enter Lost. As the two enter the subspace like area, Yuki has flashbacks involving, Yua and Ryouko making her believe that she's weak. However, Yumiko dissuades Yuki of that notion. On the other hand, Takuya suffers from his own past regrets, and communications between them and Eiji's group is practically lost. Meanwhile, Taiyou makes it to the lowest point of Lost and confronts Daichi who's personality is uploaded to a series of computers. Not wanting to waste any of his valuable time, Taiyou proceeds to delete his former partner in order to perfect the portal to Lost. Back to Yuki and Takuya, the memories of theirs that involve each other start to intertwine, which allows them to regain their focus. They then head deeper in Lost and arrive where Taiyou is as he tries to kill Daichi. Yuki then summons Akira to try and stop him. (Source: Wikipedia)
