Project A-Ko (1986) Timeline Explained – Every Event in Order

The aliens from the Lepton Kingdom of Alpha Cygni have been searching for their missing princess. D, the spy monitoring A-ko and C-ko, reports back that C-ko matches the description of their lost royal family member. Based on this information, the aliens conclude C-ko is their princess and launch an invasion to retrieve her.

Foreshadowing: D watches C-ko closely every morning, suggesting early recognition of her royal lineage.

B-ko becomes obsessed with C-ko and wants to win her over. Since A-ko is always with C-ko, B-ko launches daily mecha attacks to eliminate her rival and get closer to C-ko. Each attack escalates in power, culminating in the Akagiyama 23 powered suit.

Foreshadowing: B-ko's interest in C-ko is evident from their first meeting at school.

The movie never explicitly explains the source of A-ko's abilities. She possesses incredible speed and strength but believes herself to be an ordinary teenager, mostly concerned with oversleeping and getting to class on time. The origin of her powers remains a mystery throughout the film.

After B-ko rescues C-ko and the group begins working together, B-ko suddenly opens fire on A-ko, D, and Captain Napolipolita. This act of betrayal destroys the ship's navigation system, causing the vessel to crash. B-ko's sudden attack seems driven by her competitive nature not letting her accept a truce with her rival.

Foreshadowing: B-ko's rivalry with A-ko has been relentless throughout the film, never truly resolving.

Sixteen years before the story, an alien spaceship crashed into Graviton City, wiping out the entire population and creating a massive crater. The city was rebuilt around this crater, which becomes the location where the alien ship crashes again at the film's climax, landing on the Military Command Tower built atop the original crash site.

Foreshadowing: The opening narration establishes the crash as the defining event that shaped the current city.

After the ship crashes and the invasion fails, Captain Napolipolita and D are left stranded on Earth with a destroyed spacecraft. The next morning, they are seen disheveled on the streets begging for donations to repair their ship, showing the comedic downfall of the once-threatening alien invaders.

D reports to the approaching alien spacecraft that they have found their lost princess (C-ko). Convinced C-ko is their royal family member, the aliens travel to Earth and launch a full-scale assault on Graviton military forces to retrieve her.

Foreshadowing: D's surveillance of C-ko and the large ship approaching Earth hint at imminent arrival.

When C-ko is abducted by D during the alien invasion, both A-ko and B-ko set aside their ongoing rivalry to infiltrate the spaceship and rescue her. Their shared goal of saving C-ko creates a temporary truce, though B-ko ultimately betrays A-ko inside the ship.

Foreshadowing: The abduction happens in plain view of both A-ko and B-ko, forcing them to act together.

D is revealed to be an operative of the Lepton Kingdom of Alpha Cygni. Since the aliens believe C-ko is their lost princess, D captures her during the invasion to bring her back to the alien ship. This abduction triggers the rescue mission that drives the climax.

Foreshadowing: D's trench-coated surveillance and mysterious reporting to the spacecraft hint at a larger plan.

B-ko's attack destroys the ship's navigation system, causing it to lose control and crash land atop the Military Command Tower in Graviton City. The tower sits on the remains of the original crash site from sixteen years earlier. After the crash, A-ko and C-ko emerge unharmed while B-ko lies unconscious on the tower.

Foreshadowing: The Military Command Tower is mentioned as being built over the original crash crater, setting up the symbolic landing spot.
