Im the one using it

Last time in i was reborn in attack on titan as a bender

"You heard them, give your explanation genius,"Shadit said looking at me.

I walked onto the stage that he was standing on before walking next to the ODM gear.

"This is an omni-directional mobility gear or ODM gear for short, is a type of equipment developed by humans that allows great mobility when facing the Titans in combat, even tho it still take 10 humans using them to kill a titan. It allows the user to fight in a 3D space as opposed to a 2D one. The equipment itself takes the form of a body harness that encompasses much of the body below the neck.

Although the equipment can grant a skilled user tremendous mobility, it is a demanding art that requires both strength and skill, both of which must be honed through constant practice.That if I'm being honest the only one practice you will getting is here,the second you make a mistake against a titan you going to be in trouble."I said before pausing

Now we continue where we left off

"Do any of you guys have any questions before I move on? "I said looking at all the cadets

Nobody answered or even raise their hands,so i continued."The simplest move possible with the ODM gear is simply aiming and firing the grapple hooks at an object and then activating the gas mechanism to reel oneself toward the said object. Granted it become less efficient if you are in an open area because you have less place to hook yourself unto"I explained

"If you are creative and talented enough you can manage to do some really great stunts to help you out of a sticky situation, but apart from that i don't think you guys need to know anything more, make sure you have a great balance before trying it or you will fall,"I said before looking at the crowd of cadets, I was getting stared at by a bunch of them but I frankly didn't care.

"If there are no more questions, I'm going to go back to my spot,"I said making sure that everyone understood, because I don't want to explain this stuff again.

No one said anything, and i just slowly got out off the stage.

I did not pay attention to anything that happen afterward in i was just lost in my mind just thinking of random stuff.

So while everyone was trying out their turn in the ODM machines, I was just lost in thought,I decided to pay attention for a second and i saw a green eye kid that was going on one of the machines, and he looked very confident in himself.

He got on it and managed to balance himself for a few seconds before he fell and his head was about to imprint itself on the hard wooden floor.

The sound of his head hitting the wooden floor was heard throughout the training area.

"That must have hurt"I muttered looking at the kid.

"So much for killing all the Titans"I heard a voice say next to me

"He was talking so much yesterday, guess he all talk, "Another voice said

'Guess i missed Eren's Speech about killing all the titans,'I thought.

"Cadet jack,it is your turn to try it out, "Shadit said

I walked onto the stage and because Eren's machine was the only one available, that was the one that i used.I got on it and for some reason, i felt like it was loose.

As soon as i thought that,i was no longer in control of my own movement as the machine try to give me the same treatment as Eren but unlike him,i did not hit the floor but my face was literally an inch away from getting the same treatment.

"Why is this thing so loose"I muttered before using air to push myself back into a standing position, to everyone else it looked like i magically got back to standing when my face was literally inches away from the floor.

I leaned back as my body went back at breakneck speed but stopped before my head hit the floor,I was just looking at the sky when i heard the voice of Shadit say "Cadet Jack do you think this is a game"

I flipped back into my normal position before saying"Nope but this machine is busted"

"Then how can you use it so well if it is busted," He said staring straight into my soul

"Because I'm the one using it, make anyone else use it and they will have their face implanted into the wooden floor just like Cadet Eren showed us"I answer nonchalantly

He looked at me for a while before he told me to get off which i did, he checked the machine and saw that it was broken.

"Arogante bastard"I heard a random voice say

"Mister Shadit are we doing anything else today"I said looking at the bald teacher.

"No," He answers

I just nodded before walking off somewhere in the background,i didn't even look back in continue to walk with my hand in my pocket.

Time-skip

I was just relaxing under a tree when I felt the familiar presence of someone approaching me,i open my eyes to see Mikasa looking at me.

"Sup" I mutter still with my eyes half open.

"Nothing much"She answers

"Did anything else happen after i left?"I asked half bored

"We just continue to practice after you left, Shadit told us that we will have to work harder" She added

"So nothing much, to think that I'm stuck here for the next 3 years of my life,"I said dead tired

"You said that as if you are going to work hard at all, "Mikasa said with a deadpan expression face

"I'm just happy i don't have to sleep in a dorm with everyone else"I said

"What do you mean by that"She said a bit surprised

"You seem to forget that i can fly, and can sleep where even i want"I answer

"Sorry that i can't remember all your abilities,it not like you get a new one every year or so,"She said with sarcasm clearly present in her voice.

"Oh I'm sorry that i try to evolve what i already have,"I said

A gentle breeze pick it up and i fell asleep under the tree not caring about anything.

A/N if yall wondering why Shadi is not treating him like everyone else it is because he knows Jack and he knows full well why he is here and what Jack is capable of.
