Powerful computer with internet, catering from a major restaurant, large fridge stocked with lemonade and soda, big screen TV and DVD player with a large library of anime DVD's, and of course, life-size posters and display cutouts of my favorite anime/game characters, including one of my original trainer Lisa that I would have commissioned by a major anime character designer.
And I'd probably have one of those big plush velvet sofas and recliners for relaxing time. And somehow, most of this stuff would have to fit in the storage areas of my tour bus when traveling between shows (except maybe for the TV and furniture lol).
