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?
If we dig along the thin, but stable stratum
إن حفرنا على طول الطّبقة الرّقيقة والمستقرّة 
.المتّصلة بهذا النّفق، فلا ينبغي أن تنهار
Wenn wir entlang der dünnen,
aber stabilen Schicht graben,
Si cavan por la tierra fina
y dura de este túnel,
Si cavan por la tierra fina
y dura de este túnel,
Se scaviamo lo strato di terra sottile
Se cavarmos nesta parte fina aqui,
Если мы прокопаем этот тонкий,
но крепкий грунт, обвала не случится!
