"You heard me, our target's de-" Lisa started, getting a death glare from you.

"ONE more week..." Lisa muttered, heading to her room and getting some gym gear on.

"Well, I'm getting some exercise. Feel free to come if you wish," Lisa says, coming out in her usual gym outfit.

You shrugged. "Why not?" you asked.

"You two go and leave me to the babysitti-" Luna tried only to be pulled out by Lisa.

"Nope, your coming, little sister," Lisa said. "Guess I should too," The Joker said, shrugging.

"Scared?" you say. "Well, I've been waiting for one of my gang members to spot us and kill you," he said with a smirk.

"Oh, a couple of gang members against a gang leader. I'm so scared, not like even you could take care of them let alone me," you say, pretending to be scared.

"Haha, so funny..." he said sarcastically. "Your ego will be the death of you," he informs you.

"No, you will," you say while quickly taking the seat.

"Thats Luna's seat, Lina. Or The Joker's. Or anyone but yours," Lisa protested.

"Not mine! I'm going on my vehicle," Luna says while seemingly disappearing.

"H-How-" The Joker stuttered out. "She disappears into the shadows for a couple seconds, allowing her to hide and run," you and Lisa inform him in unison.

"Ah, understood..." he mutters.

"Well, I'm heading to my vehicle, then," you say proudly, uncovering your vehicle when that annoying voice chimes in.

"Aww, not gonna sit next to your boyfri- HEY!" The Joker had slapped Lisa before she could finish, leaving her with angry muttering.

"Great, meet you at the gym. Think he'll be there?" you asked.

"If that creepy pervert is there I'll kill him and that'll be that," Lisa states, zooming off as you do the same.

We go in and me and Luna go to two lockers and get out our gym gear, sneaking in glances at Lisa to see what happens.

Lisa's POV

I walk in and head to my locker, seeing a note on it.

Let's both get naked, whaddya say?

-Your body stalker

I take the note and crumple it, throwing it away and turning to see the pedophile-like boy behind me as he started measuring me.

"Weirdo, do you even box or do you just come to this gym to stalk me and inspect my body?" I ask, pushing away his measuring tape.

"GOD DAMMIT, stop measuring me!!" I shout.

"Um, girl, of course I box," he says triumphantly. "Prove it, throw a left hook at me," I say.

His expression morphs back to his pervy smile. "But first, can I measure your feet?"

I exhale and spot something in his pocket, picking it up and giving him a death glare.

"Hold up, are these my panties?!"

He nods, proud of himself. "I stole them from the locker room."

"Ok, this has to end right now, dude." I pick him up by his collar. "I'm gonna beat your body."

I pull him into the boxing ring. "Objectifying girls is rude. We have personality's too, we're more then just hot body's," I explain.

"Show me your boobs," he says creepily

"Someone just hit the god damn bell, PLEASE," I plead.

I hear the bell ring and start punching, sadly, he can dodge.

"Can I cover up all of your shapes with some lube?" he asked.

"Here's two shapes I've got just for you!" I say, punching him twice and knocking him out.

Y/N stepped up. "THIS is the sister that killed my gang member with one punch?" she asked.

"Mhm, I can tell your the sister who almost blasted me to Pluto when it happened," I remark with a smirk.

Y/N's POV

Nothing but angry mumbles and mutters were a response. You then went to train by The Joker, pretending you didn't spend most your time looking at him.
