The Odd Jobs encounter a strange sword at Tetsuko's smithy, and it grows attached (quite literally) to Gintoki's behind!
Even if they run into brick walls, 
as long as their cores stay intact,
،حتّى وإن صادفوا جدرانًا صلبة، فما دامت نواتهم سليمة
Aunque caigas, puedes forjarte de nuevo
si tienes un corazón fuerte.
Mesmo que se bata num obstáculo,
 basta o núcleo continuar intacto
