DD Hokuto no Ken

Synopsis

Modern day Japan… a peaceful country with no violence, and surely with more than enough food and water! Having no use for their ultimate assassination technique 'Hokuto Shinken,' Kenshin and his brothers have a hard time adapting to everyday society (Just ask their neighbors!). With or without food and water, every day is a struggle to survive in the urban jungle of Tokyo…? At least there's lots of fun along the way (Source: Silent Manga Audition)
