Keizoku

After the events of the series, Shibata has lost her memories and is reassigned. Meanwhile, a strange case regarding a cursed tree that kills whoever's name is written on its trunk surfaces among mysterious deaths. Following different leads, Shibata and the Unsolved Cases unit will meet again as they investigate. Asakura, it seems, is also plotting behind the scenes...

Graduating at the top of her class, elite detective candidate Jun Shibata is transferred to the section that handles cases deemed "unsolvable" by the department. Her partner, though a well-respected and experienced detective, has grown complacent after unsuccesfully pursuing these cases that many consider an exercise in futility. With her upper class breeding, her colleagues don't expect much from her either, but she suprises them all with her motivation and astounding powers of deduction. Well-constructed mysteries and colorful characters abound in this stylish and edgy police drama.

Like the original series, "SPEC" will revolve around a pair of police detectives as part of a special division solving difficult cases (Mishou). Touma Saya is a woman with an IQ of 201 and an inability to "read the atmosphere" in social situations. Due to a previous case, her left arm is in a sling. Her partner Sebumi Takeru used to be the star performer of the Metropolitan Police. After some incident however, he was transferred to Mishou. Those two track down offenders with special abilities(SPEC) who managed to get away with their crimes.
