"A Mother's Edge"

Prompt: Yelena Belova is now the mother of her three year old daughter Emma Belova, they are at the park, where Emma is riding her bike. It’s been three years since Yelena Belova abandoned the life of her assassin lifestyle for Emma. Her past comes back to haunt her when both the red room and shield come into her life. Her older sister Natasha brings trouble. Yelena is forced to defend herself and her child from forces who want Yelena to return to being the cold ruthless swordswoman she was as the white widow. Yelena in the past was known for her dangerous swordsmanship wielding her katana with unrivaled precision and versatility; her technique is based on battōjutsu (drawing blade techniques), a style of Japanese swordsmanship which involves directly attacking with quick, precise sword slashes through drawing the sword from the scabbard. However, it is also mixed with other hints of Japanese-styled swordsmanship but also with a bit of iaidō/iaijutsu (which normally involves quick-drawing the blade for an attack before re-sheathing it to take on another incoming attack). When her katana is still unsheathed, Yelena also often uses the scabbard itself as a weapon, using it for blunt strikes, or to block an enemy's attack. Due to this style, Yelena commonly wields Yamato with one hand, holding the scabbard with the other. On lesser foes, the 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, one of yelena's signature traits is to 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 is forced to grab her katana and fight back to make sure her daughter has a childhood. This mother will always protect Emma from her past.
