Yusei's Troubles
While Yusei is out testing their new engine, Jack and Crow discuss the changes that have recently taken place in their lives. The two grow concerned for Yusei, as Crow points out that he does tend to keep some of his feelings to himself rather than share them with his friends. The two decide to go find him and figure out what's troubling him once and for all.

When they meet up with Yusei, he reveals his unease around Ghost, and tells them that he suspects that Yliaster is behind everything, as Roman had told him that it was a man from Yliaster who set him down the path of becoming a Dark Signer. Furthermore, they are using the WRGP for some mysterious plan, if Sherry was to be believed. The three decide to work towards mastering Dark Glass's Accel Synchro as a means to effectively combat the new Yliaster plot and to protect the city.

Elsewhere, a unconscious man washes up on the shore of a beach.
