Prologue
After taking care of the bomb threat, the taxi driver is revealed to have died during questioning which is relayed by Fukuzawa to Kunikida. Shortly after, Rokuzō contacts Kunikida and reveals that the emails sent is coming from Dazai's computer.

After the call, Kunikida invites Dazai for a drive and heads to an old abandoned storehouse. Kunikida confronts Dazai pointing a gun against him. Kunikida demands Dazai to prove his innocence, otherwise he will shoot him.

Afer Kunikida's confrontation against Dazai, Yosano contacts Kunikida and tells him that the agency has received another threat from the Azure Apostle.

It is revealed that the Azure Apostle is planning on framing Dazai as the mastermind behind the string of events.

Case
Kunikida and Dazai starts their search and heads to the location of the tracking device planted by Dazai to the enemy. Before they reach to the location, Kunikida is contacted by the agency and says that they were contacted by someone on the plane. The agency soon transfers the video call to Kunikida's cellphone.

Kunikida soons gets in contact with a girl named Chiyo who is crying as the aircraft they were in rocks back and forth. Kunikida calmly asks Chiyo the situation in the place. Chiyo responds that the engine stopped moving and the steering wheel doesn't work. Dazai takes over the call and helps the girl calm down and calmly orders Chiyo to take the communication device to the captain.

Shortly after, Kunikida and Dazai is able to get in touch with the captain of flight 815S revealing that they are unable to contact with any control towers and had to resort to internal navigation. He then asks who is on the other end of the line. Kunikida and Dazai reveal themselves to be the Armed Detective Agency and will be handling the situation as the military's deployment forces won't make it in time.

The two tels the pilot that the plane has been purposefully sabotaged and asks him if there are strange devices on board. Thepilot responds that his copilot discovered a large iron box in the freight room.

Kunikida deduces that the device must be interfering with the aircraft system. He then remembers about the defunct National Defense Force developing equipment capable of crippling aircraf functions. Kunikida givea a thought that cutting off the control unit's signal on ground would likely restore control of the plane.

Kunikida gets in touch with the pilot, telling that they are going to remove the source of the problem but the pilot needs to be prepared to regulate the plane's altitude.

Following the location of the tracking device, they soon arrive at the defunct National Defense Froce. Out of nowhere, they are attacked by four men shooting with rifles. Kunikida urges Dazai to enter the building while Kunikida distracts them by throwing a flash grenade on them.

Dazai rushes to the maintenance depot where the tracker's device signal is coming from. He then arrives at the operations room. As he approaches the communicator, a big man stands behind him. Dazai tries to trick the man telling that he works undercover for their boss and the agency have found them. Much to Dazai's bewilderment, the man takes on the lie and leaves the room. As soon as the man turns his back, Dazai attacks him with a bottle of liquor causing the man to fall to the ground.

Meanwhile, Kunikida follows Dazai. However, some sort of patterns appear below Kunikida. He finds a blonde guy appear from the shadows. Kunikida is then slammed to the ground by the guy with an ability user who is responsible for the taxi driver and Alamta's death.

While Dazai tries to operate the communicator, he is attacked by the big man who was knocked out before. Dazai is continuously attacked by the man in the process. While being restrained by the big man, Dazai glances at the window at the storage room below and finds Kunikida fighting against an ability user.

Kunikida continues to take on the ability user. The ability user reveals to be a buyer in the organ-trafficking syndicate. Soon after, the ability user gets hold of Kunikida's notebook making his ability completely neutralized. He shows the release key needed to control the plane and snaps it. Meanwhile, Dazai takes another blow into the face causing the window to be shattered on impact. Dazai and Kunikida's eyes meet and the two switches place.

Dazai nullifies the blond man's ability and is able to defeat the blond man. Meanwhile, Kunikida is able to throw the big man, eventually hurling him though the window frame where the big man falls off down to the first floor.

Kunikida soon recreates a release key for the communicator. He soon is able to operate the communicator's control panel and press the disable button that will let the plane have full control again. Kunikida contacts the pilot and tells him that he shoud be able to control the plane. After much trying, the pilot is able to get control of the altitude.

Resolution
Kunikida and Dazai is able to save the plane from crashing and the case came to a close.

Since then, the agency has been busy dealing with the aftermath, interviews with the police, insurance claims and dealing with news agencies.

Novel and Anime Differences

 * The former defense force facility in the light novel houses a transmitter to a device that paralyzed a passenger airplane's operational systems, where Kunikida and Dazai head to in order to override the transmitter to prevent the airplane from crashing into Yokohama. In the anime episode, the facility is the location where the transmitter can deactivate the bomb itself.
