When transfer student Ryoichi Kyogoku appears things take a turn for the weird. Students are missing school, the student council bans cellphones, and Kyogoku begins changing students by awakening their psychic abilities to prevent a future disaster on Earth. Kenji Seki and his friends get caught in the middle and must try to figure out what is going on in time to save their friends and the future.

Claude sets his plan in motion, pitting several international organizations against each other by offering Yin up for sale. As a war between factions erupts, Hei rushes to rescue the Doll - but it might be too late to keep her safe.

Hei hears of a coming event, one predicted fifty years ago: the arrival of a girl with world-changing power. Later, after his past with Amber forces him into battle against several Contractors, Hei learns Yin could be in trouble.

Hei is troubled by Yin’s changing demeanor and her risky plan to draw their enemies from the shadows. The Black Reaper’s concerns are validated when he’s forced to battle a sultry Contractor and her twin enforcers.

After the events of Season One, Hei and Yin are on the run from the Syndicate, posing as newlyweds in Okinawa. Unfortunately, their faux honeymoon ends when a violent group of Contractors attempts to abduct Yin.

Prophesies are fulfilled, and Suo faces her destiny. Even as her memories fade away beneath the shining moon, hope remains - and a new era begins.

Suo encounters someone she thought was dead and learns the truth behind the mysteries of her past. Unfortunately, the meeting is cut short when several Contractors launch an attack.

As Kirihara uncovers the connection between Dr. Pavlichenko’s family and the Syndicate, the incredible secrets of Suo’s past are revealed. Later, Hei becomes the main suspect when a member of Section 3 is brutally murdered.

Kiko and Kurasawa help Suo search for her mother. After a mysterious stranger points the young Contractor in the right direction, a long-awaited reunion leads to an unbelievable revelation.

Aboard a speeding train, Hei’s team is ambushed by Russian authorities. In the ensuing battle, Suo and Tanya recall the times they shared in the past as friends - and clash violently in the present as Contractors.

Suo and July find themselves in a dangerous situation thanks to a double-crossing supposed ally. Later, when the young pair is abducted by an especially sinister Contractor, BK-201 must spring into action.

Hei learns the truth about the mysterious Izanami. If BK-201 wants to reach the object before it’s destroyed, he’ll have to defeat Genma - and stop Suo from pulling the trigger.

After Section 3 pushes Suo and Hei deeper underground, BK-201 must resurface to steal an object known as Izanami. The mission could get complicated - the agent tasked with guarding the object is none other than Kirihara.

In Japan, Suo begins honing her combat skills under the watchful eyes of Hei and July. Meanwhile, Kirihara - still puzzled BK-201’s disappearance - gets acquainted with the agents of Section 3.

Hei and Suo attempt to flee Russia, but their escape efforts are hindered by Contractors and gun-toting soldiers. As the body count rises, Suo finds herself undergoing a shocking metamorphosis.

On the run from several Contractors, Suo hides out with Nika and decides to take action. She devises a plan to attract the attention of the deadly BK-201 - and chaos erupts when her plan works perfectly.

Suo’s life changed forever the night a meteor fell to Earth and turned her twin brother into a Contractor. Now, two years later, the authorities launch an attack on her home - but her biggest problem is the sudden appearance of a masked killer.
