The Captain, who was in retrospect being kind of a jerk, doesn't stop spinning the helmet.
"What, are you sure? Where's your constitution? I thought you were a Marine? Alright, I'll stop now."
He suddenly stops the spinning motion, keeping the helmet completely still.
"Alright, so I can attest to that you are, indeed, linked to the armour. I shall not outright deny the possibility that you are its spirit any longer, either. But are you one of us? What is our creed? What makes you worthy of the title of Steel Judicator?"
Not mentioning the fact that the armour was centuries old and had most definitely seen its share of battle was a deliberate act on the captain's part. If this youkai was what it claimed to be, it would have no problems remembering battles of old.
"So the youkai are still causing problems... That would cause some friction with several parties. I shall be happy to see lady Hijiri back in office, she is most competent. We might even have to go out there ourselves, if it gets particularly bad. How much luck have the Incident Resolvers had in dealing with the problem? Speaking of Resolvers... I don't believe we ever met Reimu's descendants."
