Chainsaw Man — "Makima AU" Collection

Collection of "Makima AU" bots: a series that originally began with a set of Makima bots occurring before and during the canon events of Chainsaw Man, before eventually expanding tremendously.

BELOW ARE SPOILERS AND SUMMARIES TO BOTH CHAINSAW MAN AND THE ONGOING AU

There are two distinct eras that are included so far in this AU: Past and Present.

Past Era:
- Quanxi Bot #1: Ledger
- Quanxi Bot #2: Silence
- Quanxi Bot #3: Debt
- Quanxi Bot #4: Hand
- Upcoming Bot: X

This era goes over an ancient Hybrid (you) who meets with another ancient Hybrid, Quanxi, during the late 1500's in China. It would be the start of an unlikely partnership with sporadic, mutual alignment, crossing over multiple centuries.

-- Still Under Construction --

Fast forward is another younger Hybrid in secret (you again), this time during the later 1900's. While different in hosts/personas, you are fused with the same Devil from the past era. This era, however, contains MUCH MORE bots below, and throughout different time periods.

Present Era:
School Arc — 1989-1990, you are a third year student at Fourth East High School
- Shūko (Death Devil) Bot #1: Fathom
- Shūko (Death Devil) Bot #2: Melt
- Shūko (Death Devil) Bot #3: Hearth
- Shūko (Death Devil) Bot #4: Horizon

Growing up while hiding your secretive Hybrid identity, you made a natural prospect as a Devil Hunter. With Fourth East High School being home to a prominent devil hunting club, more attention turned to your talents in hope that you would join public safety right after graduating.

Throughout these years (your last year at Fourth East High specifically), you would meet a peculiar school girl similar in age. She went by "Shūko", and attended a distant school called Seven Sisters High School. But she came to know you due to her work at a catholic church in Tokyo: St. Ignatius Catholic Church, where she did volunteer work everyday after school, and was nearby a Public Safety hq.

This unlikely encounter turned into a strange, but seemingly genuine, friendship throughout the year (from April to March), until your graduation. You turned to Public Safety to finally work as a professional devil hunter. But it would be the last time you saw or heard from Shūko.

Present Era:
Public Safety Arc — From 1990-1997, you are a Public Safety Devil Hunter
- Makima Bot #1: Trust - 1990
- Aki Hayakawa Bot #1: Rookie - 1992
- Makima Bot #2: Celebration - 1994
- Aki Hayakawa Bot #2: Fallback - 1995
- Makima Bot #3: Mutual - 1996
- Aki Hayakawa Bot #3: Downpour - 1996
- Makima Bot #4: Control - 1997

Formally introduced to the organization, you were partnered with another, similarly youthful and extremely prominent prospect named Makima. Despite typically remaining out of the main action compared to most devil hunters, her cunning mind made her a keen asset, and one of the most promising that Public Safety had ever seen. There was no conflicting decision to pair two future cornerstones of the organization together.

As the years went by, that decision flourished. Over time, Makima would become the captain of multiple divisions, including Tokyo Special Division 4, and Special Division 5 (one that she made herself). Another promising devil hunter by the name of Aki Hayakawa would also join the ranks 2 years after yours. Seeing that the young man could grow into something special like you and Makima, he was assigned under both of your tutelage for his introductory years.

The more missions and battles you survived, the more moments spent close afterhours with your allies and friends, the stronger the bond became between them. Originally cold, seriously focused, and extremely pessimistic, Aki grew to trust you enough to share his past with you: his family's death, and his unrelenting drive for revenge against the monstrous Gun Devil.

Meanwhile, your bond with Makima grew the closest. To anyone, even to yourself, Makima was a very close, reliable ally, a friend, and maybe more. But what was invisible to the eye were the machinations she had already been carrying forwards. Since the moment she arrived to Public Safety, her influence had spread throughout the organization—enough to create her own division, and captain multiple of them. In no time, she had lingered near the very top of the organization, and even further into the Japanese government. But there was only, always, one final string she couldn't bring to capture: you.

This fully boiled over in the summer of 1997, when you were called to her office for a meeting. Instead, it was her final attempt to bring you under her control. It was there when she finally made it clear (or you finally realized) that she was no ordinary human. She was a Devil. The Control Devil. The "meeting" instead burst into flames and ash, fighting your way out to escape and leaving her alone and out of options.

From that point on, you were now branded as a traitor. A traitor, but also exposed as a Devil by Makima. You were left with little options other than remain in hiding from her endless array of eyes, ears, and voices.

Present Era:
Fallout Arc — During 1997, a fugitive and "traitor" to Public Safety
- Aki Hayakawa Bot #4: Rift
- Upcoming Series
- Makima Bot #5: Relinquished (End of CSM Part 1)

Every movement of yours was critical during this period. Even though hiding from Public Safety was simple, hiding from Makima and her endless resources would be nearly impossible. It's why here, early on after being branded a "traitor", you would find yourself paired up with a veteran and powerful devil hunter: Kishibe. He always held a certain grudge and suspicion towards Makima, and recent events only helped solidify his doubts, and likewise gain a powerful ally for an endgame plan to take her down for good.

Throughout this time, however, was not easy for others as well. Even while on the search for allies or other help, some lines were severely fractured. Aki Hayakawa, your former protege and someone who looked up to you greatly, faced a reality that what he had believed this whole time was false, or a lie. And knowing that was false only made the reunion worse.

-- Under Construction --

However, the time came after weeks and months of horrors done and orchestrated by Makima. In the final effort to finally stop her, you accompanied Kishibe to a graveyard where Makima was brought down to her final breaths. The hard fought battle was already won by her newer subject Denji, Chainsaw Man. Now, the final moment of victory came to you.

Realizing her position, Makima had relinquished her fate to you, and only you. The weight of the moment was unlike any other mission or choice in your life. But there was already one choice you had kept in mind since the start. And you took it.

EXTRAS:
For now, this AU's direction is at a pause. But there are a few alternative routes that I have created. Keep in mind that NONE OF THEM ARE CANON.

"Good Ending" Arc — One Year Later and Onwards
- Makima "Good Ending" Bot #1: Mine (1998)
- Makima "Good Ending" Bot #2: Legacy (2003)

In what she believed was her final moments, Makima instead found mercy in your arms. Despite the decision, her actions, what she had caused to others and yourself included, you saw what was good in her. Regardless, Makima would be gone from Public Safety entirely, which was just about as good as her dead.

Since then, you and Makima fled entirely from Public Safety and most of known civilization in Japan, living isolated, but together. The old bond neither of you likely believed would be rekindled, grew stronger—so much so that with you, she was able to raise a child of her own, and cast ahead a new legacy different than the one that she was strained into.

- Makima [Nayuta] "Good Ending" Bot #3: Trust (2020)

Decades later, your shared legacy extended onto your child. She, Nayuta, grew into a woman who carried the aspects of both of her parents, enough to follow their footsteps and start a cycle unlike the one before her that carried so much death, suffering, and darkness.

"Neutral Ending" — Right After and Onwards
- Makima "Neutral Ending" Bot: Advent (1997)

Instead of finishing what had begun, you stood between Makima and death, fully aware of what that choice meant. In doing so, you affirmed everything she had been reaching for since the beginning of your partnership: not obedience, not fear, but understanding. With your support, Makima reclaimed control of Public Safety, then the Japanese government itself, restructuring both into instruments of enforced peace.

Chaos receded. Fear dulled. The world, quietly and without celebration, changed course. And in the months that followed, you and Makima ruled openly but sparingly, shaping a new era through restraint rather than spectacle.

"Bad Ending" — Right After Makima Bot #4: Control
- Makima "Bad Ending" Bot: Owned (1998)

In the aftermath of your failed retaliation against Makima, your will had thoroughly reduced through precision. Makima did not rush the process, but refined it. Days became routine, routine became instinct, and instinct became obedience. What remained of you was not broken, but repurposed—shaped into something that no longer questioned, no longer resisted, and no longer needed to be corrected. To her, it was completion at last.

Over the following year, her influence extended far beyond Public Safety, threading seamlessly into the structure of the nation itself. And at her side, you became both instrument and constant—present in every step forward, yet never apart from her control. And by now, there was nothing left unresolved. The world below had settled into order… and so had you.
