Origin slicer

Name: Origin slicer
Gender: none. (It has no mind, soul, or weapon spirit)
Age: ♾
Kills: unknown (people killed have never existed)
Weapon type: sword

Properties:

Worthiness Judgment: The sword will judge if a being is worthy or unworthy of wielding its power.

Temporal immunity: The sword is immune to timeline changes alongside the user.

Reality warping immunity: The sword is completely immune to reality-altering powers alongside the user.

Indestructible: the Sword is unable to be broken or damaged.

Causality immunity: The Sword's personal causality is independent from external systems. This grants it immunity to causality-related abilities, natural and supernatural laws, and essentially protects them from any unwanted effect. This effect also extends to the User of the Sword.

No origin: The sword has no beginning as it existed before 'THE CREATER' created existence.

Origin slice immunity: If 'origin slice' is used against the sword then nothing would happen since it has no origin to slice or erase.

Description: origin slicer is a sword that has no set appearance, but would take the form of what the wielder desires.

Lore: It is said that the sword came to being from 'THE CREATER' itself before existence even began, but no one truly knows if this is true since the sword just appeared one day, without warning, in the middle of a battle between gods. The sword was used by a mortal to slice and erase every god in the way. In the end, no one knows that this event even happened because only one remained from that battle..... 'The Mortal.'

Special abilities:

Origin slice(active): as the name suggests the sword is able to 'slice' the origin of anything. For example, if you kill someone with it, then that person's origin would be erased, in turn making the person to have never existed in the first place, but did the person really ever exist in the first place? Another example is if you cut off someone's finger then that person would have never had that finger in their entire existence. In addition, if you scratch a person then they were born with that scratch. This ability applies everything from grass to the omniverse.

Origin slice after effect negation(passive):
This ability allows the user to retain the memory of whatever got its origin sliced. An example is when you kill someone you would remember that they existed. (This is the only reason why the origin slice ability is even known)

Abilities:

Never miss(passive):
This would make it so you would never miss your target even if you just swing in a random direction, with your eyes closed, you would still hit your target without error.

Perfect match(passive):
This makes it so the weapon would change, depending on the user, to be the 'perfect match' for the wielder so that their battle efficiency can reach their maximum battle potential possible and beyond.

Soul bound(passive):
Only the user can use the weapon unless they specifically allow another to use it. In addition, the weapon would never be lost as it would appear in the user's hands when wanted.

Weaknesses:

This weapon has no weaknesses, but the wielder can be defeated as the sword does not provide any kind of immortality or strength buffs. The only thing that this sword directly provides is some immunities to certain abilities and protection from its 'origin slice.'
