1987 Akitsukuni coup attempt

Dissatisfied with this result, in late 1987 a group of Imperial Armed Forces officers led by Yukihito Tsuge launched a coup on the grounds of restoring order to the nation after the War, using ongoing minor protests by nationalist groups and some armed forces units as a pretext, with the ultimate goal of restarting the war and destroying Elwha. This takeover, later known as Wakizashi Night, soon spiralled out of control as both the public and many in the military regarded the action in an extremely negative light. A terror attack in Heian and the subsequent heavy-handed counter-terrorism activities suddenly resulted in open rioting and clashes between civilians, police, and the military. After the Imperial Square Incident, where coup-aligned military forces fired live ammunition against civilian protesters, the coup leaders immediately stepped down and resigned from their military positions.

Immediately after taking over, the officers arrested the previous PM and Yukihito Tsuge legally dissolved the Gikai and cabinet.

Three years after the events of the first movie,[4][5] Noa Izumi and Asuma Shinohara are now testing new Labors at a facility run by the Metropolitan Police. Isao Ota is a police academy Labor instructor. Mikiyasu Shinshi has since been reassigned as the Tokyo Metropolitan Police's head of General Affairs. Seitaro Sakaki has retired with Shigeo Shiba taking over his position as head of the labor maintenance team with Hiromi Yamazaki, Kiichi Goto and Shinobu Nagumo remaining with the unit as Kanuka Clancy had permanently returned to New York. Most of them had been replaced by fresh labor pilots.

Suspicious events begin to materialize with the face of a military takeover of Tokyo by GSDF forces and martial law[3] after the Yokohama Bay Bridge is destroyed by a missile,[4] with belief that the JASDF was the culprit. Protests in various JSDF bases take place as a means of conveying their denial of the bridge attack. Before long, public panic comes as JGSDF-marked gunships attack in several bridges in Tokyo Bay, various communication centers and SV2 headquarters, coupled by the release of a supposed deadly gas after Special Assault Team snipers shoot down an auto-piloted blimp that was responsible for jamming all electronics in the Greater Tokyo Area.

Goto and Nagumo once more assemble the original Section 2 members in an abandoned subway passage as they embark on a secret operation to apprehend Yukihito Tsuge, a former GSDF officer who planned the terrorist attacks as revenge for the failure of a UN peacekeeping operation in Cambodia back in 1999.[4][5] With the threat of US intervention looming unless the government controls the situation, the team uses an old stretch of the Ginza Line to approach an artificial island Tsuge uses as his hideout. Goto also takes care of things on his end by facilitating the arrest of Shigeki Arakawa, a GSDF intelligence agent who is actually one of Tsuge's cohorts. After a fierce fight inside the artificial island's tunnel which results in flooding, the team evacuates the tunnel while Nagumo breaks through to finally arrest Tsuge.

First day
Wakizashi Night as it started around 7 PM with troops moving into Heian. Some units refused to move and blockade themselves in their bases. The senior military leadership resign immediately. The Gikai Complex is taken and Tsuge legally dismisses the PM, dissolves the Gikai and the Cabinet. Martial law is installed and a curfew is imposed.

Media centres are secured in the night but the local police do not cooperate and block the coup's process.

The first riots begin, and some activists attempt to block more troops from entering Heian as soon as the coup is announced. Protesters clash as nationalists and moderates fight.

Death of Yuria Doi
A truck runs over 6-year old Yuria Doi. This sparks a major protest that locks down downtown Heian.

Second Day
The coup leaders attempt to coordinate, consolidate and move to declare their rule. However, other military units refuse to comply.

Saishi Incident
The Imperial Air Force deploys fighters over Heian, which the coup forces threaten to shoot down.

Nishikawa bridge attack
At around 10 pm, a reconnaissance unit of the 47th Infantry Regiment was intercepted at the edge of Heian. Its commander, Colonel Daisuke Ishihara, issued a plea for the coup leaders to step down. It soon transpired that the 47th was attempting to investigate the situation and was poised to enter the city. Ishihara was ordered to stand down and return to his base at Niihama, but the 47th continued to move into the city limits by 11 pm. Ishihara could no longer be reached.

In response to this, Tsuge approved the deployment of one of his helicopters to provide a warning to Ishihara to withdraw. The helicopter gunship proceeded to the Nishikawa bridge, where the 47th was attempting to cross but was blocked by a coup-aligned unit. Due to communications difficulties and unknown factors, at around midnight the gunship fired a salvo of air-to-ground rockets that destroyed the bridge. Leading elements of the 47th withdrew immediately, with conflicting reports of sporadic gunfights breaking out between the different Army units.

News of the bridge attack rapidly spread, with fears that a full civil war would occur soon leading to more calls for the coup leaders to step down.

Third Day
Things all go to shit.

Imperial Square Incident
In the early morning, the Army opens fire on protesters in Imperial Square, killing a large number of people. Confused orders.

The coup leaders immediately step down.
