Heartbeat

. . .

"Unfortunately All Might will not be joining us, Nurse Higurashi will be joining us in his steed, however she will late due to an injury she's attending to in class 1-B."

Is what Aizawa said at the start of their class that day. And most if not all had forgotten that their loveable nurse was coming in as the substitute, especially in the midst of a villain attack. So it was a surprise when a pink barrier came to life around Aizawa, protecting him from a particularly deadly punch from the Nomu.

"How dare you." Kagome spat. Aizawa weakly looked up at her, eyes begging her to not get involved to save the students first.

But little did he know she had already checked on the students, and made sure they were okay. Glancing down to him, Aizawa saw the anger ablaze in her eyes and knew he could not change her mind. His vision started to fade and he desperately tried to fight it, but the blood loss was significant.

"Some villains you guys are, needing a muscled up experiment to do the dirty work." She taunted, the Nomu though recognising it could no longer touch its victim, started to run towards her looking for a new punching bag.

Shigaraki who watched his Nomu changed targets did nothing to stop it, merely looking disinterested in her.

Midoriya screamed for his teacher, he had been witnessing it beating up his teacher and she was just the school nurse. He watched in horror, terrified at the thought of the damage the Nomu was going to inflict upon her.

Kagome's eyes glowed, her blue eyes now a neon pink as her hair floated around her. Power crackled around her, electrifying the air. The atmosphere of the battlefield had shifted, it had become humid and everyone in the area felt their skin crawl. Kagome, though looking unbothered, silently raised her hand towards the Nomu and clenched it into the fist.

"How pitiful."

The Nomu, barely a metre away from her, stopped in its rampage towards her. It started to howl in pain, grabbing its head, wailing and throwing itself around. It collapsed onto the ground, groaning and whimpering, it started to experience seizures and its whole body started to convulse.

"Whats wrong with it?!" Shigaraki growled out, his creature continued to writhe in pain. It's howling caused many battles to stop and observe the newcomer.

"That things soul is fragmented, there are multiple pieces of different souls being kept together by a small thread." Kagome stated, her eyes electric pink and her hand glowing, she made a slow plucking motion and the Nomu cried out. "I'm merely unravelling the thread. One by one. It's an excruciatingly painful and slow process to feel yourself slip away."

"You…" He seethed. "Who are you to deny me my right to see All Might crushed?" Shigaraki vexed, this woman, he had not predicted All Might not attending and one hell of a substitute. Said woman calmly walked to Aizawa, she positioned herself so that his injured body was between her feet, she knelt down and began to ease his pain by healing him, never taking her eyes off Kurogiri and Shigaraki.

"I would suggest you retreat, unless you want to end up like this creature." She nodded towards the Nomu, who was now foaming at the mouth, her hand aimed at the Nomu started making a swirling motion, and it cried again.

"Tomura, I think it's time for us to go." Kurogiri informed, hand on his shoulder pulling him back towards the newly opening portal. This was't a pro-hero threatening them, this was different. Her face was cold, calloused, her eyes…. they were sharp and calculating, as if a hardened warrior defending her comrades was standing before them. She was protective, yet efficient, debilitating the main threat and intimidating the others. Whether it was premeditated or heat of the moment decisions she was making, one thing was clear.

She was dangerous.

"Fine." Shigaraki gritted out, his frustration clear on his tense form as he backed slowly into the portal.

Both villains left, and All Might smashed his way through the doors. The other pro heroes appeared and sorted out the low-level goons, taking roll call of the students and teachers. Kagome's adrenaline still ran through as she used her quirk to heal Aizawa's eye injury, said man had been unconscious since she stepped in. Principal Nezu and Recovery Girl came up to her, the rodent principal placed a hand on her shoulder.

"Kagome, it's okay. We are here." She looked at him, wanting to protest, but her nose started dripping blood.

"You've done enough, please cease." She still hesitated at his command, she pulled her hands away and her eyes stopping glowing.

Before she could take care of her bloody nose, a sudden wave of exhaustion came over her, her vision dotted black and she started to fall. All Might rushed and caught her before she fell to the ground.

"She hasn't used those abilities properly for well over a year now, I'm impressed she still had so much control." Recovery Girl stated, assessing her and Aizawa.

Midoriya eyes followed his teachers as they were carried off, however just as they were about to carry Kagome, Recovery Girl stopped them and placed her hand on her intern's neck.

"Her pulse is slowing, place her on the ground immediately!" They began prepping the nurse for transport to the hospital, as class 1-A watched in horror that their loveable nurse was currently about to go into a cardiac arrest.

The class was tense, the teachers tried their best to push the students out, however the whole room was thick with worry. It wasn't until Jiro confirmed to the class that she heard Kagome take an audible breath, and they got her heartbeat back to normal, that they relaxed visibly.

Aizawa was also being carried away from their view, the blood still staining his clothes and with no sign of consciousness.

Eyeing their teachers being carried away, Midoriya and his class watched tensely. They were scared for their teachers… yet even more worried for the future.
