This episode of Meisaku is inspired by "period drama." Meisaku and others are in the world of period drama. However, a lot of things look too contemporary.
You're afraid of a punishment 
that didn't exist back then?
In der Edo-Zeit gab es
diese Strafe dafür nicht!
¡Ese castigo no existe aún!
Cette peine n’existe pas,
à cette époque !
Ma non esisteva una pena simile in epoca Edo!
Mas prisão perpétua 
não existia na era Edo!
Да не было тогда такого наказания!
