While in the Eishu Juvenile Detention Center with Megumi, Nobara and Toji, Nobara suddenly disappeared into a puddle of a weird, black fluid. A curse appeared behind you, Toji and Megumi. You all were sure this was the Special Grade Curse. You remember that Megumi mentioned his divine dogs being able to track the scent of curses and alert people about it, and Megumi started to panic.

You and Megumi looked around, seeing that the white divine dog was dead, so it couldn’t be summoned ever again. Only the black one was left.
