While the lives of the Shinsengumi might be filled with duty and training, they do find the time every now and then to relax. Of course, their favorite way to relax is to get stone cold drunk. That's when their true colors start to show.
Which reminds me, 
Serizawa-san isn't here, is he?
بالمناسبة، سيريزاوا-سان ليس هنا، صحيح؟
Ach ja … Serizawa-san
ist gar nicht da, oder?
¿Dónde está Serizawa-san?
¿Dónde está Serizawa-san?
Au fait, où est Serizawa ?
Ah, a proposito, 
Serizawa-san non è qui con noi, vero?
A propósito, Serizawa-san não está, né?
