Once the conversation that I had with Rin yesterday ended, he lead me back to my room making me rest up for a very early morning.

And that's where I was. Laying in the early morning grass very exhausted because Rin has been making me do hand to hand combat with him. Trying to get me mad to unlock the demonic side.

"Tell me. What gets you extremely angry. Not pissed like your dad leaving the toilet seat up or the pervert mineta making you wear a cheerleading outfit. What makes you go batshit crazy with rage." Rin says and I think, my dad getting hurt but I don't know why the image of endeavor kicking Shoto is playing over and over in my head, but it's working cause I could feel the bones bones growing. All I'm seeing is black and I see Rin take out his sword making him burn. Until I'm finally in my demonic form.

"Good, now unlock the hellfire." Rin says and I reach down for the flames and the come up, I look at them seeing that there a blue and purple mixture. Making my whole body burn with those flames, but I didn't feel the heat at all.

"Attack." Rin says and I started using it, I made numerous attacks but the most successful one was the blasting the hellfire out of my hands and using those.

"I see you have sword! use It!" Rin yells and I grab the sword and once I brought them out they were covered in the flames and I started attacking Rin with the sword making it even more difficult to control. But that's what we worked on all day making me have a grasp on what I can use with this demonic side while managing to keep my sanity up so I didn't murder people, but that was a huge step.

The two days was the same but with different techniques, but today we only trained for half of the day because we were gonna go on patrol tonight because of the hero killer was still on the loose. So after we ate and relaxed a bit,

I get on my suit and walk out seeing Rin waiting there in his hero suit as well.

(A/n: ignore yukio please.)

We then head out onto the streets.

"I want you to look out and don't get distracted, stick with me incase something happens. Got it?" Rin says.

"Got it Rin." I say and he nods, we start patrolling and looking around until we see a a lot of smoke uphead. We run towards it seeing pro hero's fighting against Nomu's!?!

"Stay here!" Rin says and takes out his sword and starts fighting a nomu. I then felt a vibration coming from my pocket, I take out my phone and see that midoriya sent his location to everyone and he's in a alleyway in Hosu city a block away from here.

I look at Rin and see that he is too distracted to notice me gone, I then run towards the location and see that Iida and a pro hero is on the floor immobilized and shoto and midoriya is fighting, they all haven't noticed me yet so I think of something that makes me truly angry and I start to become my demonic form. Once I am fully in my demonic form I use my hellfire to blast the hero killer stain into the concrete wall making everyone look my way.

"(L/n) get out of here!" Iida tells but I don't listen and run towards midoriya and shoto.

"What is going on?" I ask and I see stain slowly get up.

"Just don't let him consume your blood. He can immobilize you that way." Midoriya says and I nod.

"What are you doing here (Y/n)?" Shoto says while blasting Ice at stain to try to immobilize him again.

"I got the text and I was close." I say while blasting hellfire out of my hands and then grabbing my sword that is consumed by hellfire then covering my body in also hellfire.

"My...that quirk seems very powerful." Stain says and running towards me and I smirk not saying a thing as me and shoto run towards him and I bring my sword up and send a wave of hellfire towards him making stain stop so that shoto can freeze his feet to the ground.

Then shoto sends a wave of of fire towards him as I emit the fire and mix it with shotos to make the fire much hotter and powerful making stain fly in the wall again but I didn't notice stain throw a knife towards me cutting my cheek. Then stain runs towards me and gets very close but a ice spike stops him but he grabs me and licks my blood but I use my hellfire to push him off of me, but I notice I'm not fallen. I then see stain spitting my blood out as shoto stands infront of me protectively.

"(Y/n) how are you not fallen?!" Midoriya yells from the place he's laying immobilized in.

"I have no idea!" I yell back and I look at stain as he get up and I see the blood is darker than usual.

"Your blood....is very unusual. My quirk doesn't work on it." Stain says and I smirk.

"Then looks like I don't need to be careful." I say and he throws another knife towards us but towards shoto but I make the fire go up to 3000° degrees and shooting it out of my hands making the knife melt instantly.

"Looks like you only have one more weapon, be careful I don't melt it." I say and shoto notices that midoriya is up and he runs towards stain and punches stain very hard making stain lose a bit of balance but he caught himself and he starts attacking all three of us with his last weapon, I couldn't melt the weapon or I would've hit midoriya or shoto, but we kept fighting until the hero killer stain cuts my stomach deeply making me fall to my knees.

"(Y/N)!" Shoto yells and the hero killer smirks at his reaction and kicks me in the stomach that's bleeding out, making me fall on my side of the concrete floor he then puts his sword above his head and was about to stab me but a huge wave of ice impacts him making him go in the wall. But I feel my demonic form disappear making me feel even more pain, I then barely hear shoto calling my out my name. I look over at shoto slowly seeing him crying his eyes out.

"Hey..you'll be okay I promise (y/n). But you need to stay awake for me! God your father will kill me." Shoto says while crying so much that I feel some tears go on my face. I don't even notice that shoto is stopping the bleeding from his hero shirt making him shirtless, but I then start getting dizzy but I look and see that midoriya and Iida tied the hero killer up before I see darkness.

❄️Todoroki's POV🔥

After I send that massive ice blast at stain I quickly take off my hero shirt and go on my knees trying to stop (Y/n) from bleeding out as I'm crying my eyes out. I can't lose her too, I already lost Touya and my mother, I can't lose (Y/n) as well.

"Hey..you'll be okay I promise (y/n). But you need to stay awake for me! God your father will kill me." I say and applying more pressure. When I look at midoriya, Iida and the pro hero native for some help. But when I look back at (y/n) her eyes were already closed, making me scream her name louder.

"IIDA GO GET THE PARAMEDICS! USE YOUR GOD DAMN QUIRK!" I yell while crying more and I check her pulse I feel a slight one and I hear Iida run away and native comes to me and takes his cape off and uses it as a new gauze to stop the bleeding.

"She'll be okay kid. Just keep pressure on her wound." Native says and I nod with more tears in my eyes and I hear the sirens and running and wheels. Then I see the paramedics run towards us as well as the pro hero's and they see stain tyed up.

"Move kid!" The paramedic says and I move away and let them do there job and I feel a hand on my shoulder. Seeing it's Iida.

"Todoroki...I'm sorry, this all my fault." Iida says and I just focus the paramedics using there quirks to stop the bleeding, Then I see my father and Rin comes towards the hero killer stain and they grab him and take him somewhere. I swear, if (y/n) doesn't make it...
