The barrier is broken. Monsters are free. Take a deep breath, because between securing monster rights, integrating into a new society, and reviving the lost art of magic there's a lot to worry about. Meanwhile Frisk and their ghost friend Chara realize exactly what is needed to revive Asriel: no less than seven human souls, all given willingly. Sequel to How to Save a Soul.
Long ago the humans went mad. Monsters built massive walls around their cities and huddled for protection, living out their entire lives within these fortifications. One day Chara appears, very much like a human but in many ways not, and insists they are a "person".
Or, "Scenes from a game like Other M that didn't suck".
