When they meet with a traffic accident, Gintoki and Hijikata miraculously escape without a scratch, but their souls end up switching bodies. With no means to return to normal, Gintoki has to live as a freedom-loving Hijikata, and Hijikata as a Gintoki who stresses strict discipline. The change in these two leaders transforms the Shinsengumi and Odd Jobs into completely different organizations.
Then if we wake up, this 
nightmare will end, right?
سينتهي هذا الكابوس إن استيقظنا إذاً؟
Entonces, la pesadilla 
acabará cuando despertemos.
Então se eu acordar, o 
pesadelo vai terminar, né?
