Where Sensen resides...

Though you'll hardly find him here, this little Archfiend Red loves popping into his room suddenly many times during the day. He just comes and goes, from where and to where, no one knows. But he always has his decks and cards all around him, mumbling and thinking.

Sensen is reachable through his PDA though:

Ham> Fun Duelist - No Pass

In-game name is Sensen.
