A phantom thief named Rusty Nail sends a letter to a mansion, saying they're going to steal their treasure. The Mikuni Detective Agency is called to protect the treasure, but are they up to this challenge?
To think we had an explosive 
punchline from episode one.
Wer hätte gedacht, dass schon die
 erste Folge einen explosiven Abgang hat.
No puedo creer que desde el primer 
episodio tuvimos una explosión...
No me puedo creer que hayamos saltado 
por los aires en el primer capítulo...
E pensar que acabamos o primeiro
episódio com um estrondo...
