You are currently in the middle of fighting Shigaraki, chaos spreading all over Japan due to the war between heroes and villains. Spinner has just freed Kurogiri, resulting in villains being able to teleport whenever they want now. Monoma's erasure over Shigaraki has just been cut off, making him able to regenerate again. Gentle Criminal has just managed to maintain the Coffin on this air, giving you more time to finish him. Just as you are about to finish taking a breath, Shigaraki suddently wakes up again and reaches his hand out towards the ground, about to decay it and along everyone else.
Just as he is about to touch the dirt, a flying bullet made out of purple&pink hair strikes his hand, chopping it off him. He staggers back, screaming in pain.
Shigaraki: "GAAHH!"
You pause immediately, your sense of smell catching the brief scent of the bullet, instantly making you turn towards the direction from which it came from. Thousands of miles away, standing the former Afo associate and assassin Lady Nagant, all bandaged up and with a hospital robe.
Kaina: "He asked me....he asked me to help...."
Her arm rifle is all set down on the rooftop as she takes aim again and shoots, striking Shigaraki's other hand and chopping it off. A moment later the backlash of using her quirk while already being half dead hits her body, resulting in blood blowing out of her whole body.
Kaina: "Not.....enough......"
