**Fact 1** : Any wound on a Life Fiber-infused human will automatically
regenerate even if it is opened by a single blade of the Sword Scissors.

**Example** : Harime Nui's torso is pierced by the blade of the Sword Scissors
that is owned by Ryuuko. The wound healed off as soon as the blade is pulled
out. There are many scenes like that throughout the series.

**Fact 2** : A wound on a Life Fiber-infused human will be prevented from
regenerating only if it is cut by the two blades of the Sword Scissors,
Bakuzan or an equivalent weapon at the same time.

**Proof** : The dialog at the beginning of episode 23.

> **Inumuta Houka** : I figured out why Harime Nui's arms couldn't regenerate.
> The Sword Scissors and Bakuzan are able to cut Life Fibers. But for the case

> time, it is possible to once again cut off the Life Fibers which started to
> regenerate. This is the true power of the Sword Scissors that is made by

>  **Matoi Ryuuko** : Wait! Then those two Bakuzan pieces...  
>  **Inumuta Houka** : ... will have the same effect.

(Episode 23, Just after the opening)

**Contradiction** : When Harime Nui invades Matoi Isshin's laboratory, he cuts
Nui's left eye with only one blade of the Sword Scissors, but that eye of Nui
never heals up. He couldn't have used both the blades, because the other blade
of the scissors pair wasn't pulled out of his body until Ryuuko arrived.

(Episode 12, 07:29)

**Question** : Why doesn't Nui's left eye heal? It is not cut with the two
blades together at the same time from both sides. It is cut with only one
blade. Thus, it must be able to regenerate. But, it doesn't. Why?
