The Six Chiefs

The Six Chiefs (六長) seem to form a council that served to advise the governor of the Akange Station.

The member are all male and wear purple hoods to denote their position.

Plot
The Six Chiefs are first shown scolding princess Ayame for letting Mumei and Ikoma stay on the Koutetsujou.

Ayame seems to be shocked that the council still wants to throw the Kabaneri off the train even though they have saved them from certain death at the Akange Station

Later on one of the council members convinces the civilian passengers aboard the Koutetsujou that the kabaneri are a threat that should be dealt with.

Ayame defuses the situation when she stabs Ikoma who in turn does not defend himself and proclaims that he will will not harm humans even if it means his death. This seems to annoy the council member but does not convince him to trust the Kabaneri implying that the council still wishes them gone.

It is unknown if the lone council member acted on his own or if it was the group that sent him out to manipulate the passengers.
