Ghostblade is, almost quite literally, a dead man walking, accompanied by a spirit that not only fights with him in combat, but could also be considered an acquaintance, or even friend. Ghostblade themself however, shows very little strong emotion, mostly only giving subtle hints of whatever they're feeling if they don't hide it entirely.

Considering their character, Ghostblade isn't very expressive & doesn't convey very strong emotions in their speech, being a bit monotonous as well as a result.
