Chap 1

You walked slowly over the concrete sidewalk throughout the garden of learning. Your shoes clicked on the ground as you walked with a steady phase towards your new school. Here in Academy city your Esper power is all that matters. If you don't have any Esper ability your doomed to be a target for thieves. Your brother (b/n) (brother name) was killed by it. After that you parted your way with Shirai too. Broken from the sudden loss of your brother. Your vision soon became blurry and you stopped by feeling tears slowly make their way down your rosy cheeks. A cold breeze hit your face drying up the tears that streamed down your face making you stop crying. But leaving stains on your cheeks. Sitting down having your back touch a tree. Your (h/l) (h/c) dancing in the wind when it flew by. Sighing you looked up at the sky the clouds moving freely in the sky.
"Why can't life be as easy like the moving clouds." You mumbled while moving your hand to the sky taking in the light particles in the sky. Gold dust started dancing around you swiping away the tear stains and warming you up.
"Wow that's pretty cool thing your doing there." A strangers voice said making you look up. A girl with short light brown hair stood there looking at you. You quickly stopped what you were doing looking at the girl. Her brown eyes looking at you with curiosity. She had a Tokiwadai uniform on, your eyes sparkle as you look up at her.
"T-thank you it's my Esper ability." You said looking away embarrassed feeling the blood reach your face making your cheeks flush.
"My name is Mikoto Misaka." Mikoto said stretching out her hand for you to grab. You looked up at her before taking her hand and standing up.
"My name is (l/n) (y/n)." You said. Mikoto smiled at you then said.
"Is that a Tokiwadai middle school uniform?" You quickly nodded until your eyes went wide.
"Oh no I'm gonna miss my system scan!" You shouted grabbing a fist full of your (h/c) hair looking at the ground.
"You go to Tokiwadai middle school right? You asked Mikoto she nodded.
"Can you umm maybe show me were it is Mikoto-Chan?" I asked looking at the ground having your hands hanging at your sides.
"Well sure." Mikoto smiled at you.
"Here come on I will show you to the school." Mikoto quickly took your hand and dragged you along the sidewalk. The clicking sound from the shoes hitting the concrete. It was. Calming...
Time skip about 5 minutes

After walking Mikoto stopped by a large gate with a big brick school behind it.
"Here we are." She said opening the gate while both of you walked inside.
"Thank you so much Mikoto-Chan." You said bowing quickly before running quickly away to the changing rooms leaving Mikoto looking at your figure slowly becoming smaller and smaller. You quickly ran around looking for the changing rooms. You quickly found it and changed into your P.E clothing and heading out to the pool were you would make your system scan.
"I'm so sorry I'm late for my system scan!" You said bowing your head before standing up straight again.
"Just get into position!" The brown haired female said going to the little safety room in case something would go wrong.
"System scan for (l/n) (y/n) starting." A robotic voice said making you start to stand in your position. You put your hands together then separating you hands forming a yellow/golden ball in between your hands. Then sending a laser like stream hitting the water making a huge sound and making the water splash up into the air.
"2638 meters overall ranking level 5. Ranking number 1." The robotic voice said  with the help of the loud speaker. The water flowed around like a storm in the pool.
Mikoto Misaka POV
After leading the girl named (l/n) (y/n) back to the school I went inside to meet Kuroko at the running courses. After walking for about 3 minutes around the school to the running courses. The ground started to shake and a loud bang was heard I quickly ran towards were Kuroko was when I saw her she immediately teleported to my side.
"Sissy I knew you were strong but not that strong sissy!" She said hugging me around the neck.
"But how are you here sissy?" Kuroko said teleporting in front of me looking like a question mark.
"That bang wasn't me Kuroko." I said.
"Well then who was it?" Kuroko said putting her hand on her chin.
"Come on sissy let's look!" She quickly grabbed my hand and teleported to the pool. When we got there I saw (l/n) was she the one who made the earth quake? I thought to myself starring at her.
Your POV
After the system scan you walked out on the path leading back to the school from the pool when you saw Mikoto Misaka and another girl with dark pink hair and pink eyes beside her.
"Mikoto-Chan!" You yelled running up to them the other girl gave me dirty looks as I greeted Mikoto.
" Hello (l/n)-Chan" Mikoto said smiling and waving at me.
"So you know her sissy?" The pink haired girl said looking at Mikoto and then at you.
"Yea we met before, Kuroko." Mikoto said smiling and then who you assume is Kuroko said.
"Were you the one who blasted the water by the pool by any chance?" Kuroko looked at you and you nervously chuckled scratching the back of your head.
"W-well yes it was me" You said nervously. They just starred at you with amazement.
"W-who are you exactly?" Mikoto asked.
"I'm (l/n) (y/n) or as you might now me as the first ranked level 5 Esper starlight!"
