Hahahaha I can't stop laughing, he is watching a girl change below you!! Haha the gunman starts freaking out not knowing how he can be seen from hundreds of meters away! Well he isn't looking at you but the girl below you changing in a clear open glass door for the world to see. Gintama just so happens to be in the right place at the right time. This sniper is in the wrong place wrong time.
Right place right time!! He's smiling. Gintama haha!!
