"The story moves violently in the interstice of the memory."

Baldr Sky is a Cyberpunk Visual Novel that takes place in a world where nanotechnology has advanced greatly and that the newer generation people have brain chips, making it easy for them to connect to the virtual space net. Baldr Sky is part of Team Baldrhead’s long running series (along with Baldr Force, Baldr Bullet and Baldr Fist). The visual novel contains elements of action gameplay with Kou piloting his simulacrum to fight. Unlike the majority of visual novels, every single character in the story is fully voiced.

Kou Kadokura wakes up and finds himself in a cyberspace battlefield controlling a giant simulacrum. He faintly recalls going to sleep in his bed at the school dormitory, but now swarms of viruses are attacking him. He later realizes that he had just suffered a brain injury and lost his memories of the past few years. His subordinate Rain Kirishima informs him that he is a lieutenant in a mercenary group and that they were chasing after the Drexler Organization, a group believed to be responsible for the tragedy "Gray Christmas" that changed Kou’s life.

The first game is named Baldr Sky: "Lost Memory" Dive1 and the second one is named Baldr Sky "Recordare" Dive2. The two games together form the complete story. If both games are installed at the same time, Dive2 will carry over saved data and also play the routes in Dive1. There is also a fandisk named Baldr Sky DiveX "Dream World", which contains several short side stories including the period that Kou spent training as a mercenary. The fandisk also includes different battle modes where you can use any mecha that appears in the story.

    • Noi has this hatred towards her father Neunzehn who illegally clone her by planting his genetic information into an ovum and caused her all kinds of suffering.
    • Kou in Sora’s route becomes depress when he realized he is a NPC, meaning that the real Kou can never be with Sora. He gets over it when he realizes that his existence is a linked with the every single Kou from different worlds and even has some of their memories.

    • In the last route, Father Gregory’s simulacrum can make two doppelgangers in battle. Killing a fake will just cause him to resurrect it at full health.
    • Neunzehn also can create one in the final battle. The real one can also quickly turn invisible to heal himself so that the player might not realize that there is a fake.

  • The End of the World as We Know It
  • Enemy-Detecting Radar: There's a map on the upper right corner that shows where all the enemies are.
  • Eroge
  • External Combustion: Nanoha’s parents died from a car bomb.
  • Evil Mentor: Kurihara is this to Kou as he was in charge of Assembler when Gray Christmas occurs and somehow was able to escape despite being in center of the incident. He was good all along but was being controlled by Neunzehn.
  • Evolving Attack: Attacking gives the specific weapon some EXP and that makes it better as it use less of the Overheating Meter. Use some weapons enough times also unlocks even better attacks to use.
  • Faking the Dead: Rain fakes Kou’s and her own death since the entire mercenary group they were part of was wiped out.
  • Fan Translation: A translator originally associated with a.f.k. had started a project, but it seems to be stalled. A new project has started up on The Imageboard That Must Not Be Named.

  • Inside a Computer System
  • Interrupted Suicide:
    • Isao in Makoto’s route. Makoto just wants some information from him though.
    • Rain in Sora’s route. Rain believed that the Kou she was seeing was a trick by Father Gregory, so she planned on killing herself when she was defeated.
    • Kou and Sora in the "Eternal" ending. Sora was dying and Kou was going to disappear since the link he has with the other worlds' Kou ends when he kills Neunzehn. They decide to die together using a grenade. Kuu stops them both and they find another solution.

    • Rain blames herself for Sora’s death since she believes that Sora went to Isao to request for her school transfer. This caused Sora to be near Assembler when Gray Christmas occurs.
    • Aki feels responsible for connecting Kurihara to the Baldr system.
    • Makoto also blames herself for pulling a prank on Sora that delayed her from taking a train to leave the location of Assembler. She also feels responsible for not stopping Kurihara.
  • Joke Character: Since DiveX allows the player to use every single mecha that appears in the game, that includes all the weak viruses. The weakest joke mecha is that one Nanoha uses, which is really slow and two of the her three normal "attacks" involves her tripping on the ground.
  • Katanas Are Just Better: Kurihara dual wields it, both in this simulacrum and in real world. Kou also has a move where he uses iaido and in Dive X a force crash version of it.
  • Kill Sat: Gungnir
  • Kill the Ones You Love
  • Knowledge Broker: Eddie
  • Legal Jailbait: Noi
  • Lethal Chef: Sora and Rain.
  • Limit Break: All characters and bosses have multiple limit breaks. In Dive1, they can charge up one limit break bar. In Dive2, there are two bars so the characters can use two limit breaks consecutively. Kou has over a dozen of them.
  • Logic Bomb: Can prove to be fatal in cyberspace. Kou’s brain chip was damaged from one and that caused to him to suffer amnesia.
  • Lotus Eater Machine: Dominion believes that the entire world is a fake and that they have to return back to the real world.

    • Gregory also uses a mental trap program "Enchanter" that shows the person the illusion of their worst nightmares.
  • Memento MacGuffin:
    • The pendant Rain has is from Kou as an apology for breaking Rain’s gift pendant. In virtual space, the pendant acts as a self destruct mechanism.
    • The pendant Sora got from Kou was originally suppose to be Rain’s gift to Kou. The pendant appears in the hands of Agent and acts as a quantum dice that detects what world it she is in.
  • Multiple Endings: There are different endings depending on choices Kou makes, on time it takes for specific battle and the victory/defeat outcome of major boss fight. The titles of the good endings are the heroine’s name.
    • Rain has a good ending and "Ghost" ending that depends on the choice of whether Kou struggles to survive or gives up trying to escape.
    • Nanoha has a time specified battle when Kou has to rush to save Nanoha. Taking more than three minutes in the battle will lock out the good ending and lead to the "Dreamland" ending. Taking more than five minutes causes a Nonstandard Game Over. Finally, losing the final battle gives the "Embrace" ending.
    • Chinatsu has one divergence path choice that leads to "Departure" ending if Kou doesn’t believe in Agent’s actions. Choosing the other path leads to the good ending or "Connected Machine" ending depending of if Kou wins the last battle.
    • Aki has a good, "Ark" and "Nirvana" ending. Good ending occurs if Kou fights a time specific battle as fast as possible before GOAT prevents them from gathering information and an important choice of accepting Aki as she is. Otherwise it leads to the "Ark" ending. "Nirvana" ending occurs if Kou loses to Tranquilizer or Isao.
    • Makoto only has a good ending and "Object Lost" ending that depend on the final battle.
    • Sora only has one ending but she has an extended "Eternal" ending that shows more on the multiple worlds ending on a happier note.
  • The Multiverse: Neunzehn and Sora have been struggling against each other in influencing parallel worlds. Originally, all worlds where Kou survives Gray Christmas end with Assembler activating and killing humanity. So Sora tries to send instructions to a revived Kuu who takes the name of Agent to save Kou. Worlds 1 to 5 (the other heroines’ routes) are results of the battle. In Sora’s route, Kou becomes a being similar to Agent in sending messages to himself in other worlds to make a better ending.

  • Nanomachines: The technology is advanced enough to that it can accomplish things ranging from human cloning and slow body repairing.
  • Naughty Tentacles: Gilberto releases this on Rain and Kou has to rush through several battles to save her.

    • Kou also qualifies as he personally takes down numerous viruses by himself in several battles.

  • Our Souls Are Different: Humans have wired ghosts that separate them from NPC in cyberspace.
  • Overheating: Kou’s simulacrum can continue to use different weapons in a combo until his Overheat Meter is filled up. Then he has to wait for the meter to fall back to zero. Limit Breaks can go over the meter and there is one limit break that allows Kou to continue using weapons even pass the meter.

  • Retraux: Aki’s personal level in cyberspace resembles old 8-bit games.
  • Say My Name: Soraaa!

    • Rain’s "Ghost" ending, doubling up as a sad reveal that the Sora Kou sees is Rain.
    • Kou and Sora in the "Eternal" end.

  • Stealth Hi Bye: Agent, who randomly appears and disappears in front of Kou.
  • Subordinate Excuse: Rain is following Kou because she loves him.
  • Sex Bot: The pirate NPCs that were illegally created from Kuu’s data. Therefore this annoys Kou since they look like Sora.

  • Inner Dialogue: In Sora’s route, almost everyone thought Kou was talking to himself but he was actually talking to Kuu.
  • Time Stands Still: Occurs several times on the virtual net where every single AI freezes up.
  • Title Drop: "Baldr Sky" is the keyword that Kurihara used for the nanomachine capsule that he gave to Kou. When the keyword is stated, it provides data about the restoration program for the Assembler.

  • Three Quarters View: The gameplay part of the visual novel is from this perspective.

  • Tomato in the Mirror: Kou in Sora’s route is actually the NPC that Aki created and doesn’t have a wired ghost. The real Kou died on Gray Christmas in that world.

  • You Gotta Have Blue Hair: Nanoha has natural green hair and Makoto has purple hair.
  • Your Mind Makes It Real: Dying in cyberspace without a limiter will most likely cause brain death from the feedback.
