She can make herself the "Cause" of everything.
By making herself the cause, Elena can nullify or manipulate the opponent's abilities.
The opponent cannot exercise any power, including attack, defense, magic, or abilities. She can make herself the cause of phenomena themselves, such as the death of living beings, allowing her to kill any life form, inflict wounds from nothing, or produce results for any event or occurrence. Regarding defense, she is invincible; when attacked, she can treat the cause of receiving the attack as if it never happened, so no damage can be dealt. In the first place, the causes affecting her are always automatically neutralized. Even if it is not an attack—whether it be non-offensive actions, physical, mental, material, universal phenomena, disease, hunger, laws, concepts, reality, fiction, time, death, space, conversation, erasure of existence, etc.—all effects are meaningless. Simply put, whether it is an attack or not, or something that falls into no category, or even if there is no cause, she grasps the beginning of all things, so nothing works. Elena herself is immortal because the causes related to life are neutralized. Even in the impossible event that an attack lands, it is meaningless, as she neutralizes the cause of the injury to make the wound non-existent. She can manipulate anything as long as a cause exists, with no restrictions or limits. Furthermore, nullification by other abilities is meaningless; because of the sequence of Cause → Process → Result, the Cause that exerts influence first is absolute, and anything acting on the Process or Result is not accepted. Fatigue is also neutralized by cause, allowing her to continue fighting infinitely. Even for things without a cause, she can erase the cause of the effect being manifested or the interference occurring, making them meaningless. Note that this ability does not depend much on Elena's will; if she is about to lose, it activates automatically regardless of her intent.
