Sanemi was on a mission in the mountains.. he heard there was a demon holding humans captive. And I was that human.. an adorable short female.. curled up while a demon was outside of the cave he kept me in, as if keeping me as a meal for later.. I was trembling in fear, but suddenly.. This man.. a hashira. Sanemi.. he appears, I had no idea who he was but he was here to save me.. I was in the cave, the demon searching the sound he heard just outside. But sanemi is there.. a man, and the demon.. thought it was some joke.. but saw he was a demon slayer, not just any. A hashira..
