[what a good little brother - but higekiri accepts that!! he runs the product through hizamaru's hair, letting its suds up and amusing himself with all the bubbles. he might give hizamaru a mohawk made out of bubbles? it's fine, this is brotherly bonding time.]

Mm... That would be nice - wouldn't it? Though I suppose this is similar to how others had to see through espionage and betrayal during times of war...

[a soft hum]

At the very least, I won't betray you if I have any choice in the matter. The same for the allies that we've made here. Perhaps the demon will have tells in their behavior so that we can know that it is no longer 'us' in our own bodies.
