Tagawa's life within the Dark Hand started with several training exercises against the other soldiers, making sure he didn't overdo it and to learn how to wield his mud in various ways.
He did his best in trying to be social and learning how to get along with others since it's been sometime since he's done such things.
Tagawa eventually was given the right to go on missions with other soldiers to further Nyoko's cause, stealing from merchants and battling bandits simply because they were good nourishment as well as fighting any imperial guards that showed up.
They weren't the imperial guards of the north but to Tagawa's mind they weren't any different, surely they've let people down as well so he'd merely kill them so that they wouldn't be able to give false hope to anyone.
