It's a good thing Tokyo has a good disaster response force, you'd think that every time Godzilla, Mecha-Godzilla, Rodan, Son of Kong, Mothra or Gamura would come stomping through, Tokyo would pretty much be in a permanent state of destruction.

However, each time that one of these monsters stomps through, then gets defeated, Tokyo manages to rebuild quickly.

This shirt identifies you as a part of that disaster response squad. The Kanji on the front of the shirt reads "Keishichou tokubetsu saigai kidoutai" literally translating to "Metropolitan Police Special Disaster Police" (via MegaGear)
