With Denki as captain, Team 5 is assigned to a mission to transport automated puppets for mining purposes to an island in the Land of Water, to test and operate them, to gather data, and to analyze the results. However, lacking physical strength, Denki isn't very useful and ends up being ridiculed. Will Denki be able to restore his reputation as a ninja and successfully complete his first mission as captain?
But in the end, with each failure,
one can make new discoveries.
لكن في النّهاية، مع كلّ فشل، يمكن 
.للمرء أن يكتشف اكتشافات جديدة
Aber letztlich kann man mit jedem
Scheitern neue Entdeckungen machen.
Pero los errores llevan
a nuevos descubrimientos.
Pero los errores llevan
a nuevos descubrimientos.
Ma, alla fine,
Mas, no fim, com cada fracasso,
fazemos novas descobertas.
Вот только каждый промах 
ведёт к новым открытиям.
