"Recollection of the Demon: A Symphony of Steel and Inferno"

Prompt: Yelena Belova regains her memories and power from her past life as Vergil Sparda. Yamato and her devil trigger forms return to her and she kills the red room with Yamato and summon swords not needing to transform. Years later after training, Yelena slaughters hydra men. Fury shows footage of Yelena’s chilling power and skill to the avengers. They all react and talk about this. They see Yelena skill where her speed, precision, and discipline bestowed to her allowed her to outpace and utterly them cut down as if akin to an artform; with great concentration in only splits of a second and issuing a number of blows at her discretion, they see how she time her victim's demise, and sheathe in sync with the damage done, resulting in a display of destruction that slays the opposition before they could even realize it. Yelena triggers turning into blue, humanoid demon, but it has several white imprints detailed on the trench coat with the three coat tails separating into four (with its design when airborne being bat-esque wings), her silky blonde hair changes into a crest that has a fin shape at the top, her neck gains a membrane that curves inwards, the spine merges with two dark-colored bones exposed at the top as well, her sheathe alters and attaches to her sleeve while becoming a clawed appendage, and her vest changes to a undercoat. Also, Yelena’s feet are unchanged but darkened, she obtains a bright blue aura and her teeth are fangs that show.
