Meanwhile, Ban, Ginji, Himiko, Shido, and Kazuki go to Makubex's computer room, only to find him missing. Shido says that his animals are not respecting his command for him, as they all sense danger lurking. They go to the pharmacy, seeing Gen again, and meeting Emishi and Juubei there. Emishi explains that Kanou attacked him, and that Masaki has returned to the Limitless Fortress. Kazuki tells everyone that Masaki was the last of the four kings of The VOLTS.

Himiko encounters Kaoru in the Mayan Temple. Shido, Kazuki, and Juubei also become virtually separated. Kazuki and Juubei encounter Kanou and Uryuu in the Grand Canyon.

Kazuki and Juubei falls off the canyon, bringing them out of the virtual landscape and back into Lower Town. Meanwhile, Shido encounters Masaki, and the two engage in battle. However, Teshimine appears and sends them out of the virtual landscape. Teshimine questions Masaki for returning to the Limitless Fortress.
