From Easy Going Scans:

Look for him in the boulevard full of sorrow and desires called Slum Street and you shall find yourself at the place of the Necromancer. He has the power and knowledge to resurrect all your loved ones—at the price of your soul or years of your life. Oh! There is one caveat... But no one willing to part with life or soul would listen to such warnings, anyway.

Make a contract with him and you’ll be swept away by a tale of life and death.

From MangaHelpers:

Another version of the story of the Inspectors and Enforcers from Psycho-Pass, but this time in chibi style! All of the main characters are now in chibi form, and are attending a "Psycho-Pass Academy," which is basically a chibi-fied version of the scenario of the original series. New student Tsunemori and her classmates will use their Dominators to keep their school's peace! [tethysdust]

From the author of Necromancer.
