As they make their way to meet up with Yuniko, Haruyuki explains to Takumu how Seiji had set him up, and dragging Chiyuri along. After hearing about their situation, Yuniko agrees to teach Haruyuki and Takumu about the Incarnate System, explaining the different skills that can be performed with them. Silver Crow demonstrates the ability he achieved via his training with Sky Raker, with Scarlet Rain suggesting he give it a name so he can have easier access to it, thus he dubs it Laser Sword. As the type of skills an avatar can learn depends on the user's personal traumas, Takumu explains how he was bullied in elementary school, which gave rise Cyan Pile's combat ability. As Scarlet Rain begins training Cyan Pile, Haruyuki logs out to learn more about how Seiji masks himself from the matching list. He is then joined by Yuniko's ally, Blood Leopard, who takes him to Akihabara to begin the investigation. They arrive and enter Akihabara's virtual world and proceed to the Akihabara Battle Grounds, a neutral fighting arena for Burst Linkers which is also being plagued by another unlisted Burst Linker called Rust Jigsaw who enters the Dive Cafe where Haruyuki and Blood Leopard's real bodies are.
