Chapter 12.3 is the third part of the 12th chapter of the Bungo Stray DEAD APPLE manga.
Summary[]
As a sign of his "friendship" with Shibusawa, Fyodor lets on that his ability remains intact and does not turn against him amidst the fog, because—with his ability phantom walking up towards him—he claims that crime and punishment are close acquaintances.
With Fyodor chanting how boundaries are destroyed and rooms are awakened, the singularity then turns into a colossal dragon, which Fyodor declares to be the incarnation of the chaos of all abilities rather than a loss of power nor a singularity.
