The Cursed Alpha

UA here we come!

Katsuski age 15 (present)

Today is the day of the UA high school entrance exams and the hero placement test. I can't fucking wait!

"Oi! Brat! Get your lazy ass up! School today!" The old hag yells up the stairs.

"I'm up!" I yell back, I get up out of bed and head to the bathroom. I get ready in record time. When I finally get downstairs I see Deku sitting at the table eating eggs and talking to the hag.

"Hey Kacchan!" He smiles happily at me, his tail swishing behind him.

"Oi Nerd your tails out." I point out with a smirk.

"Really?! Shit." He mumbles and after a few minutes it pops out of sight with a puff and green smoke.

"Language!" The hag shouts, making Izu cower and whimper. My Alpha did not like that. I feel myself start to growl and before I can the omega is at my side shoving a piece of toast in my mouth and dragging me out the door. Stupid Alpha being all protective. Why the fuck do I care?

"We're going to be late!" He calls pulling me along. Soon I can see the giant UA building with a mob of people heading up to the building for the exam.

"Oi! Nerd! Remember what we agreed?"

"Y-yeah Kacchan. I don't know you." His face falls and my heart breaks as he releases my arm before he runs up the hill on all fours.

"Good luck Kacchan!" He calls before disappearing into the crowd, his fluffy green tail reappearing for an instant.

Stupid feelings. What the fuck is wrong with me? Izu and I made up but still! He's just Izu! Sweet, Kind, fluffy, cu- What? No! Fuck! Stupid!

Izuku age 14 (present)

The UA entrance Exams are finally here! It took me the last three summers and a few trips to the doctor before I finally found out what my quirk is and how to use it.

My quirk is called Neko, basically I can do whatever a cat can do, its classifieds a mutation and transformation quirk. I can transform into a fat fluffy green tabby cat or a green tiger. It took me one summer to figure out how to hide my tail so it didn't get hurt again, it takes alot of concentration to pull it off bit it works, I still have to have my uniforms modified to accommodate my tail since shoving my tail in paints is uncomfortable and it and my ears don't actually disappear. I have discovered my speed and agility have increased so parkour is a breeze and so much more fun, I also picked up taekwondo, karate, boxing, and ballet. My strength is higher too if you didn't know I was an Omega you'd think I was a Beta. I found a dark green collar that matches my fur when I transform so I've been wearing that.

"Izuku time for school!" My mom calls from downstairs. I head downstairs after I get my uniform on.

"I'm going to Kacchan's house!" I call before leaving the house and climbing to the roof. After a few roof jumps I landed on Kacchan's house. I climb down and make my way into the house through the living room window.

"Izuku! How many times do I have to say use the door!" Antie Mitsuki shouts from the kitchen when she smells me.

"Sorry Auntie." I call back pulling off my shoes and heading to the couch.

"Izuku breakfast is ready if you want some." Auntie says before she yells up to Kacchan. Kacchan used to bully me but after my tail was sprained in 7th grade Kacchan has been my silent protector. I also found out last year that I'm gay. I tried dating a girl right after school ended last year but kissing her didn't feel right plus she wasn't even attractive. Others told me she was considered the hottest girl in the school but I didn't see it. And I couldn't get Kacchan's abs out of my head. So I broke up with her and dated a few guys that summer as I trained. Those felt better but they weren't Kacchan. I haven't told him I'm gay yet, because I didnt want him to go back to the rude, aggressive bully he was the first year and half of middle school. I was lost in thought when Kacchan came downstairs.

"Oi! Nerd! Your tails out." He smirks that sexy smirk of his making me blush and look away from him only to get a face full of tail. "Shit." I mumble and will, myself to hid my tail.

"Language! Auntie shouts unintentionally releasing her Alpha pheromones. My omega instantly submits and causes me to whimper a little. That's when I smell Kacchan. He smells angry. I force myself to stand up. I grab a piece of toast and shakily make my way to Kacchan. I shove the toast in his mouth and pull him outside.

Soon the UA building comes into view and Kacchan says the words I have been dreading.

"Remember what we agreed on."

"Y-yeah. Kacchan. I don't know you." I release his arm and run up the hill somehow needing up running on all fours. I feel my tail pop out and instantly will it back into hiding.

Once I reach the top of the hill I stand up and walk towards the billboards looking for my name.

(AN: everything happens the same as the anime minus the broken bones...Izuku also had help from Katsuski rescuing Uraka from the 0 pointer.)

The entrance exams were hard. I'm sore all over and I think I sprained my tail again. Also my hand is killing me. I hope it's not broken. Oh well. I'll wrap it when I get home. As I'm walking home I hear Kacchan yelling at someone he's affectionately named Shitty Hair. I don't pay attention to his conversation as I make my way past him and the guy, tears threatening to fall. Shit! I can't be jealous! He's not gay! Ugh! Being in love with Kacchan hurts. Fuck!

"Oi! Deku!" I hear Kacchan yell out to me. I took off running down the hill only for Kacchan to grab my tail that reappeared. I hissed in pain.

"Let go Kacchan!" I cry out in pain both physical and emotional, my tears now falling. He lets my tail go only to grab my arm and pull me close.

"K-Kacchan...were in...p-public." I say around my tears. Kacchan responded with his signature "tch" and nuzzled his face into my neck.

"Hey! Bakubro!" I hear someone calling out to Kacchan. Reluctantly I pull away from him.

"Oi! Izu I'm coming over." Kacchan says as a redhead with shark teeth, Eijiro(?) jumps onto his back earning him a place on the ground as Kacchan swung the guy over his shoulder and onto the ground with a loud thud.

"What the fuck shitty hair!" Kacchan shouts some of his anger-filled spicy cinnamon and caramel Alpha pheromones leaking out making my knees go weak and my omega submitting with a show of my collared neck and a suppressed moan as his scent engulfs me.

"K-Kac-chan." I weakly mumble, slightly trembling. Looking around I see other omegas in my position from Kacchan's outburst, they seem more scared of him than me. Huh. Must because I've been around him since childhood.

"Shit! Sorry Nerd." Kacchan says when he notices my position. He takes a few deep breaths and slowly his pheromones start retreating and going back to his normal sweet cinnamon and caramel smell. I collapse onto the ground along with the other omegas around. Too weak to walk or stand, I just lay on the ground and breath the fresh air that's slowly filling with Kacchan's even sweeter cinnamon calming pheromones.

"Shit. Shit. Shit. I'm so sorry Izu." Kacchan whispers when he's close enough to me.

"Whoa, so the green cat was this cute omega?" The red head, definitely Eijirou, speaks up. Kacchan growls a warning at him as he scoops me up and takes me to his house since my mom won't be home till closer to midnight.  With a shout of, "see you in school Ei!"over Kacchan's shoulders, I curl up in his grasp and slowly let sleep take me.
