Once Hikari actually got into the car, everything would happen quickly, but she first had to calm the young boy that was screaming or he'd probably break an eardrum or three. She grabbed his hand from smashing against the window and held it gently, but tight enough to keep him from moving, and with the other hand loosened the chest strap on the infant so that it was no longer pressing against his throat. "Hey, it's going to be okay. I need you to calm down though, can you do that for me? Tell me where you're hurting." She said it in the softest voice that she could, hiding just how much it was trembling. She was a shinobi, it was her job to be calm in situations like these, and while there were some things about the accident that she would be unable to ignore as factual, it was hard not to get choked up about the back seat in particular. Most of the woman's chattering in the front seat had been directed at other's so she didn't give a response, but she heard what she had said. It almost made Hikari's stomach turn.
Angels.
She was no angel, but that was a problem for another time. The longer she spent in this car the more at risk everyone was. She didn't have warm clothes on anymore, and it was starting to snow heavier, as well as the smell of gas eventually would just start to make her nauseous. Even she wasn't immune to things like this. While she spoke to the boy after he hopefully calmed down, she started with the baby, and thankfully it was right as help was arriving. An entourage of Nara clansmen rumbled the streets with their footsteps, and Hikari was so glad that one of them would undoubtedly be Hyosui's father. He was like a father figure of her own, which would be inevitable, and it comforted her to have them both there watching out for her.
Angling her body awkwardly against the car seat, she started to undo the seatbelt and loosen the small child extremely slowly so that the little boy didn't slip out of it and tumble to the roof of the car. She was there ready to take him into her arms, supporting his head in the crook of her elbow. The car seat unlatched without issue, but she had a feeling the two older kid's belts would pose more of an issue for her if the mechanism decided not to work for whatever reason. Shimmying on her knees back toward the window, she ducked down and was met by a pair of hands. The clan was preparing to administer medical attention on site, with blankets galore and supplies, and someone was there to help get the children out of the car. She handed off the baby and as someone took him from the person who'd received him, they wrapped him in a thick blanket and took him away to be taken care of.
Hikari held her hand out the window and asked for a knife, and she only waited a few moments before one was set in her hand. "The others are older, they'll be at risk of getting cut up by the glass down here. If there's an extra blanket I suggest laying it down." Her voice almost sounded kind of remorseful as she carefully crawled back over to the boy that was awake. The cuts would be the least of their worries but it would at least help avoid unnecessary injury and for her- well everyone knew what would happen if she got cut deep enough. It was why she was going so slowly and carefully, and making sure that her hoodie was underneath her at all times to protect her from the glass. If her blood was in this car if it went up in flames the explosion would be three times the normal size.
"Okay, it's your turn, and then I'll get your sister out. And then I'll help your parents, but we have to get you out of here and checked out first okay? Just be calm, and moving around will hurt more. Stay as still as you can, and trust me. I'm right here, okay?"
She pat his hand gently before she reached down and attempted the clasp on the seatbelt. The knife was set aside momentarily to free her hands, just in case the belt released- and it did. As he started to slide out of the seat she was quick to catch him, shifting his body as he came out so he was laying in her arms like a princess. As she laid him down across the roof of the car with his head next to the open window, someone was sliding a blanket in to cover up the edge of the window and the broken glass. They took his shoulders in hand and as Hikari lifted his legs behind is knees, she helped slide him out of the car. He received blankets and medical attention immediately as well. Which left only the daughter. Things were going smoothly but now there was more weight on one side of the car than the other if Hikari moved. Right now she was still on the opposite side so it was balanced, but it would very easily be thrown off if she moved at all.
"Hyo, are you holding up okay out there? ... If I move to the other side, the car will tip- it won't be balanced anymore. I need you to keep it from tipping, okay? There's going to be more weight on the passenger side."
