Killua As Deku

3

(Never expected them to collaborate, different styles and all. Bring me the horizon is actually good though)

They all stood there, alarmed. Aizawa turned on his quirk, tsukaichi got into a stance and so did hawks. Killua just sighed.

Killua pov
I knew there was someone outside eavesdropping, I couldn't tell them what I really thought. I'm pretty that this isn't my universe, maybe the future, since it may have evolved that much.
"Calm down, I won't do that to you if you don't mean any harm to me."
"Truth." Tsukauchi said.
They relaxed, but were still kinda on guard.
"Also, there are people outside eavesdropping, and I need to tell you something that has to be kept a secret."
They got the signal, and went out to tell them to leave. I kept en on so I would know if they came back.
"Okay, what I am telling you must be kept a secret unless I give you permission to tell others or else..."
They got my point and all agreed.
"Just to confirm, do you know who the zoldycks are?"

"Yes. They are famous assassins that started long ago, but no one saw their face. They started to separate into two, one which they are vigilantes and the other is considered villians. They were never caught."
Yep it is confirmed.
"Okay, don't freak out, but I'm from the past."

"WAIT WHAT!" They all screamed in sync.
How slow...
"My full name is killua zoldyck, and I am an ex-assassin. I was forced to be an assassin and was going to be heir of the family, but I didn't want to kill, so I escaped home. I'm sure you know what hunters are. I went to the exam when I was twelve but got disqualified, but I passed the next year. My the enemy I was talking about is my brother illumi. If you wanna know more, bust ask. Don't try finding my files, pretty sure they don't exist."
They all just stood there. Pretty sure I broke them. Baka.

"Wait, so you killed before?" Hawks spoke up first.
"Yep, didn't like it, but I think my kill count is higher than most mass murderers and villians."
"Truth"
"You're a hunter?"
"Yea, so technically killing is legal for me."
"Truth"
"Wait, do hunters still exist?" I asked.
"Yea, but there aren't a lot left. I think like... 10?"
"Can I meet them?"
...
There was silence.
"I mean... If you can find them..."
"Oh, I'll find them easily... does hunter licenses still work?"
"Yea, but best not to use it, we haven't seen them in ages." Tsukauchi replied.
"I'll keep that in mind..."
"Does that mean you can get into kukuroo mountain mansion?"
"It's still here? Yea, I can."
"Without getting killed?" Aizawa asked
"Yep!" I said popping the p.
Is Mike still there? I hope so...
Suddenly, a doctor came rushing in.
"How are you standing? You're supposed to be unconscious, or at least in immense pain!"
"Training."
...
"Get back in bed, you have to heal."
"Yea, lie down, lie down."
Suddenly, everyone was just trying to force me in bed. In the end, I just gave up and sat down.
"We'll come back when you're better. Goodbye." Aizawa said, then they just left.
I lay in bed, thinking.
Is my family still living in there?
How will I get back?
Is nen still used?
Where are the rest of the hunters?
Is Gon ok?
Gon...
I started feeling out of breath, anxiety building up.
Dang it, my separation anxiety.
I was fine when I had alluka, but now...
The heart monitor started beating abnormally fast, alerting the nurse.
"Calm down!"
She was also panicking.
Someone came in, I'm assuming it's a therapist or doctor.
She saw the situation and let out a calming aura, and a familiar scent. No, scents. There was a forest scent, Gon's scent. Then there was a sweet one, alluka's scent. I calmed down soon, and turns out she was a therapist.
"Are you feeling better now?" She asked. I just nodded, not wanting to be engaged in a conversation.
"I'm aki, if you ever want someone to talk to or anything, just ask for me or give me a call. Here's my number." She gave me a card, and just left.
Handy quirk, she could be a hero, but I guess it is more useful here.
(I don't really like OCs but I'm making and exception)
I'm really tempted to escape, but I still stayed. I need more information, and the way to kukuroo mountain.

(Time skip cause idk what else to put here)
My separation anxiety is getting worse, but I guess I'll manage.
Today is the day I'm getting discharged, and the day those heroes are coming back.
"Killua?" A familiar voice said. Aizawa. (I just realised they never told him their names, so let's just say they did)
I just nodded as a greeting, you know, I have manners.
(Don't lie killua)
I'm not lying! Now back to what's happening...
"We bought someone new. Meet nezu, the principal of the top hero school of japan."
When I saw him, I immediately jumped into action. I scaled the wall and stuck on the ceiling corner(cieling, get it? No? Sorry... fun fact, ciel means sky in French. If you get the joke, comment, and you are royalty), hissing at him.
"What's a chimera ant doing here? I thought we killed them all!"
"How do you know I'm a chimera ant? And killed them all?" Nezu said.
"I've met them! They're the reason my friend was on the verge of death!" The images of the incident flooded my mind.
"I promise, I mean no harm." Nezu said.
I could feel my breath quicken, an anxiety attack creeping up. I fell down from the ceiling corner, curling up in the corner of the room.
"Dang it! Call a therapist or something!" Hawks yelled. I couldn't think straight. All I could see was blood, gon's blood...
The familiar scent and aura came in the room, and slowly, I calmed down.
"Aki."
She sighs, and looked at me. "You know, I could put a permanent scent in something. Would that help?"
I nodded, face flushed from embarrassment.
"Tell me something that you like, preferably an animal, so I can get a plushy or something like that."
"... frogs." They always reminded me of Gon. "Can it be a necklace, please."
She smiles softly, and nodded in agreement.
After that, she left. The heroes decided that if I should stay anywhere, it could be with Aizawa or in kukuroo mountain. So we set off for the mountain.
When we got there, the mountain was even taller than I remembered. The heroes started walking, while I just looked at them amused.
"We're never getting there at this pace. Follow me."
I knew we were going there today, so I booked the travelling bus in advance for them they were full so I'm going up there myself. We got to the bus stop and waited, being last in line, and it was pretty convenient for my plan. Hehehe... *insert cat face*
