How can Levi be so fast when approaching the Beast Titan's nape in season 3 part 2?


In episode 17 of _Attack on Titan_ season 3 part 2, when Levi takes out the
Beast Titan's arm, eyes, and legs, Levi is in the air above the downed titan.
When Levi goes for the kill, Zeke says that he doesn't have enough time to
harden his nape. ([YouTube

Levi was in the air, reeling in towards the Beast Titan. The ODM wire was
still taut but the ODM gear was set to reel speed. It's demonstrated time and
time again that when people using the ODM would listen to the order from the
captains/whoever was in charge, they all move at the same speed and don't seem
to rehook. They just stay there.

We saw Annie/the Female Titan harden quick enough to be protected from Oluo
which was really fast.

But back to Levi, there weren't any tall freestanding objects in sight, so how
did he move so fast? Please don't say it was gravity. He wasn't falling, he
was reeling.




  1. First: He's using more gas, as Mikasa did in S1E7.

But how can they use more gas? There is no valve as you can see in the
pictures.

I re-watched episodes 7 and 8 from season 1 multiple times but they said:

> No one knows how the ODM works except engineers

So I can only guess maybe they hold the "gas fire button" (as you can see in
the second picture there are two buttons on the handle, the bottom button is
for using gas) for a long time or maybe push it rapidly or push it with more
power. I really don't know and I searched the whole of the internet and it
seems no one knows.

  2. Second: He's an Ackerman as explained on the [Fandom Wiki](https://attackontitan.fandom.com/wiki/Ackerman_clan):

> The Ackermans have an "awakened power" displayed by some members of the
> clan. Levi Ackerman describes it as "knowing exactly what needs to be done,
> and it lets the Ackermans exhibit physical abilities far above the average
> human. Eren Yeager learns from Zeke that this is because they were the
> result of the old Eldian Empire experimenting with the Subjects of Ymir.
> They can manifest the power of the Titans as humans, without becoming a
> Titan or inheriting any of the Nine Titans. When awakened, the Ackerman
> gains the battle experience from every single Ackerman before them via
> paths.
