In 2022, Asumi, Eri, and their friend Iori all play The World R:X together as Sakuya, Mary, and Tobias respectively. On one occasion, they happen to be in the dungeon containing The One Sin event while Shamrock's guild was trying to defeat it. While trying to reach a good spot to watch from, Sakuya accidentally triggers a trap that instantly kills many of the guild members.

Hermit wakes up in the strange area to find that everyone was gone or had been corrupted by the AI. He starts looking at the items the players left behind trying to find his list until he gives up and hires Geek to make a new one. Hermit starts using it to identify the corrupted players.

Shamrock analyzes Sakuya's right hand and determines that Sakuya/Asumi is a partial lost one, since her hand has been absorbed by the system (leading to the real-life tingling and the fact that she can feel things in-game that are done to that hand). Sakuya also tells Shamrock that on the night that Mac Anu was invaded, Eri improved for a little while in real life before going back deeply into her coma, proving that the corrupted Eri they saw in game was connected to the real Eri and that the data drain temporarily helped her.
