The Odd Jobs encounter a strange sword at Tetsuko's smithy, and it grows attached (quite literally) to Gintoki's behind!
As time passed and I grew 
older, I lost my edge.
.وبمرور الوقت كبرت في السّنّ، وفقدت مهاراتي
Con el paso del tiempo,
me volví un blandengue.
Conforme o tempo foi passando e
 fui envelhecendo, perdi o jeito.
