You have to find him quick and this is the fasted way you can think of.  You run up to the stage and grab the microphone......
  "Mamo-chan, where are you?"  you scream into the microphone.
  "What
are you doing?" the DJ asks.
  "I have to find Mamo-chan he---"
  "GAURDS!!!"  the DJ interupts.
  Three strong men come charging at you at you duck easily.  Then a huge one grabes you by the shoulders and gives you the boot.  What should you do now?
Wait for Mamo-chan to get out
Go home
