The description on Arc 3 states that his data wasn't found in Fenrir so probably I may want to explain it here.

"leaving the world he grew to care and like the people." means that he disappeared from the world as a result, erasing himself from everyone's memories except for Laura. He also couldn't meet the newbie(Kaze) since time was almost up(about 3 or 2 minutes left). Last effort? Ditch everyone so he won't cause ruin and havoc in the world(Which... appeared in Arc 2 while he was travelling through the dimensions and ended up in the future).
