Fire Force (Manga) Vol 16

THE GRAY OF HAIJIMA

Now that Company 8 has learned that Haijima Industries is using children in an attempt to spark an Adolla Burst, Shinra is eager to put a stop to their heinous practices. To infiltrate their facilities, he agrees to let them study his own powers, and now he must face one of the ghosts of his childhood--the evil Kurono, a twisted pyrokinetic with enough power to rival the toughest soldier on the Fire Force.
