In Joker’s closet is an attic accessible via a drop-down ladder. It is sound proofed, and has an electronic lock that can be keyed to accept unlock requests from specific phones. The interior has the feel of a converted-for-living factory landing and is quite large. There are long floor-to-ceiling windows which face outwards, to the view of Tokyo-F. An industrial, wall mounted fan provides cooling.

A large bed with more than enough room for three people occupies the non-windowed wall of the attic, with shelves located just to the side of it. A white board sits between one set of windows, along with a weathered looking leather couch and some stools. A thermostat next to the board allows for heating and cooling the room as desired.

For some reason, when not in use, the white board is always just covered with changing recipes for various illicit and often explosive substances?
