You woke up. You were in a strange place. You then heard a voice in your.

System: "Well, hello, there! You can call me System and this is my Phantom Field. I'm basically a god, so now you'll have to fight in Tag Battles! Keep the Keystone if you want to go back home."

Ruby: "Where am I...?"

Weiss: "My head... What is this place?"

Blake: "We should be cautious."

Yang: "Who's even that voice?"
