The second defense (a Kny hashira story)

What would happen if all the hashira suddenly died. The slayer Corp would fall without it's pillars to keep it up. So this is the reason the second defense was made. As strong as hashira without the hashira actually knowing, a group of humans and demons together fighting side by side. When a hashira goes on a mission 2 or 3 of the second defense follow them to protect them if needed. So when Sanemi (the wind hashira) finds 2 of them a human and demon talking with the leader of the Corp before a hashira meeting he tells the rest of the hashira. At the meeting they bring it up but aren't prepared for what they hear.

Author here if I put a personal note in the story it will [look like this].
