"Basic first-aid?" Sorry Codi, first-aid isn't a thing yet where he's from. Rokuro has more knowledge and experience than most, in that he is aware of how to fashion a tourniquet, set a bone, and remove an arrow-- the basics of battle-field injuries. For most other issues people of his time tend to rely upon opium, acupuncture, and offerings to the gods.

"I know how to stop bleeding, and stitch wounds..." Rokuro's brow is similarly creased, although heroism couldn't be farther from his thoughts. Once again he finds himself ignorant in the worst way, and now innocent people may suffer for it. "If you give me directions, I will follow them to the best of my ability."
