Yuriko has another run in with her sister Ms. Mari and Misaki, restoring much of her memories. Now she has to choose between Nebula or her sister.
- Foreshadowing: The mention of Duo using Yuriko and Regal as his probes and Wily trying to study the changes Duo made to their genes would become important later on in Stream.
- Heel–Face Turn: Yuriko performs one, saving Ms. Mari from Dark Proto Man.
- Tragic Villain: Yuriko turns out to be this. During a family vacation when they were children, Ms. Mari fell ill when it was time to return home.

Stream reveals they were found by Dr. Wily where he performed tests to study the changes Duo' effect had on them.
