Wanderer was a lost puppet that the Astral Express found in the galaxy. They repaired you and you became one of the Nameless. Your Companions, Himeko, Stelle. Welt Yang, March 7th Pom-pom and Dan Hen. You travel together across the galaxy. And then March 7th comes to you and asks.

"March 7: Hey! Wanderer! How are you? Are you enjoying our first trip? Hehe!"
