"Stop I-it kachann you're making him cry" I heard Izuku say, tears welling up in his eyes. "Stupid Deku you can never be a hero," Katsuki said his words angered me. "SHUT UP KATSUKI MORI-SAN MORE OF A HERO THAN YOU'LL EVER BE!!!!" I yelled running in front of Mori-San. "Oh yeah and what about you a quirk like yours is the quirk of a villain," Katsuki said, he really knows how to piss me off. My quirks where my parent's quirks. I was the only kid in the family to get both. My quirk is called "blood control" and "bone chains". What this means is that I can control things in my blood like, temperature and I can turn it into weapons I also make blood faster than normal people. With "bone chain" it is what is it says I can summon chains from my arms; these chains are made of bone. (Wow really author-Chan) "you don't know anything about me katsuki!" I yelled "then let's end this" katsuki said with a large grin on his face. Then out of know where he used his quirk to make a giant explosion in front of me. But because I already had cuts on my body from training with mama and papa, I didn't have to hurt myself. Instead, I use my blood as a wall.

'Why is she doing this she's going to get hurt' I thought as (N/N)-Chan yelled at kachann. "Then lets end this" I heard katsuki say with a twisted smile on his face. 'That smile is really scaring me right now' my thoughts were cut off by kachann. 'Oh no, he used his quirk' I thought as I saw an explosion surround (Y/N)-Chan. "Hah, you'll have to do better than that katsuki!" (Y/N)-Chan said 'she's okay thank the gods' I thought as I saw (N/N)-Chan standing there unharmed in front of...... a really pissed off kachann. 'Oh no,' again my thoughts were cut off by kachann. He swung his fist at (Y/N)-Chan, but before he hit her she grabbed his wrist. 'What is she going to do know' I thought as she flipped katsuki over her shoulder making his back hit the ground hard. As kachann struggled to get up he mumbled "you may have won this time but next time, I'll take you down"

I turn around to see a scared shitless Mori-San. "Are you okay (Y/N)-Chan?" Izuku said as he ran up to me. 'Man I really hate worrying him' I thought as I walked to Mori-san "yeah I'm fine what about you" I asked 'I swear to god if katsuki hurt you I'm going to rip his head off' I thought as Mori-san ran up to me, then he incase me in a bone-crushing hug. 'He must have been really been worried' I thought with a small smile. I hugged him and pat his back "I'm okay Mori-San promise" I said he pulled away from the hug, then looked me dead in the eye. He looked so worried "you promise," he said tear in his eyes. "Pinky" "remember (Y/N) I get to break your pinky if break a pinky promise," Mori-san said. I smiled remembering his promise to me "yeah I remember Mori-San" "okay then (N/N)-Chan let's go to the nurse"
"Okay Mori-San"
'What would I do without you'
