New Student (Reader x HAREM) (Jin x Reader!Sister!)

Chapter 9

NORMAL P.O.V.

Opening your eyes, you could see the white ceiling of your bedroom. You sat up and yawned. You looked at the clock beside your lamp and grit your teeth. "I can't believe I overslept" you whispered to yourself. You pushed yourself up and did your morning routine. It was 9:57 in the morning and class started at 8:00 a.m.

You put on your uniform, socks, and shoes, grabbing your bag, you walked downstairs and didn't bother to eat. You went up to a vending machine and bought yakisoba bread. You munched on the bread and felt a sudden strong gust of wind blew by you. Due to the strong wind, your Yakisoba bread fell to the ground. You looked down and sighed.

The air suddenly became dense. You sensed a familiar scent making you drop your bag and take out your talsimans. "Kegare (Impurities) ?" you mumbled to yourself. The whole island began to look like it was devoid of life. The grass no longer there, the sky looked like it was contaminated. The trees were all cut down and everything looked like a contaminated, and unhygienic area. The buildings all broken down. "The seal must have broke" you mumbled and sighed. "Onii-sama, I trust you with the students" you stated. The ground began to shook. Several Kegares began to walk around the island. "This is gonna take a while"

Jin's P.O.V.

I never thought that the seal broke. I guess someone is responsible for it. I'm sure Y/n is already taking care of the Impurities, I have to lead everyone to the gymnasium since Y/n put a seal around it. I walked in the audio room and pressed the button. "Everyone, please head to the gymnasium asap. I repeat, head to the gymnasium. Security level 5 has been breached, head to the gymnasium immediately" I pressed the button, ending the announcement. I hurriedly walked through the hallways and ushered all the students to go to the gym.

I then saw Yuno helping out Jenock. "Guys! Kegares are here! Let's head to the gym!" I widened my eyes at that. "Yuno-san, how do you know about Kegares?" the brunette looked at me with a determined look on her face. "I was taught by my cousin, everyone let's go!" I grabbed her shoulder. "If any Kegares come near them, help me, okay?" the brunette nodded as we began evacuating the students. They headed outside quickly. Some began to panic once an Impurity headed towards us. I took out a talisman. "I may not be as strong as my sister, but I'll do anything in my power to protect these students" "Bind! Vines!" Yuno shouted beside me, holding a talisman. The talisman I held began to glow and soon changed to a katana. I ran towards the Impurity, I cut across it's neck and once I landed on the ground, the Kegare blew up.

"Hurry, everyone!" Yuno shouted behind me. ( I recommend that you guys watch Twin Star Exorcists )

The students and staff were now in the gym, some we're huddling in groups, scared for dear life. Hanako was shaking, crying on Yuno's shoulder. The headmaster walked up to me with a frown. "I've never thought that the seal would break so soon" I nodded and looked at the scared students. "I feel a bit worthless, my sister is out there fighting while I'm here, doing nothing" I stated bitterly. I'm so weak. I should be stronger than Y/n. I need to protect her. I'm supposed to be the one to protect her.

"Don't say such things, Jin" I looked at the headmaster as he patted my back gently. We then heard a scream. I loud crash was heard and I saw Y/n creating a hole on the roof and landed on the ground on her feet. "Sis!" I shouted. Blood was slowly dropping from her left arm. I haven't seen her this injured before. I looked in horror when a Basara created another hole on the roof and landed in front of Y/n. The students were getting scared by the second. The Basara had wild red hair. He had dark skin and yellow orbs like any other Basara. I never thought a Basara could break the seal.

Y/n quickly went behind him and snapped her fingers. "Everyone, cover your ears!" I shouted nd covered my ears. A wild and strong gust of wind began to swirl around the gym like a tornado. A few seconds, the wind died down. Y/n had a blank look on her face while the Basara had his eyes wide. A bright beam shot down to him from the skies as the star symbol was carved in front of the Basara. The Basara was now gone. Y/n wiped the blood on her katana. "Now my uniform is all bloody" I heard her say in annoyance.

She took out a golden talisman and made the seal around the island. I sighed in relief. I ran up to her and wrapped my arms around her body. She looked so fragile. She looked up at me. Her lifeless eyes was now bursting with life. She had a warm smile on. How I missed her smile. She hugged me back. "I was so worried" I whispered in her ear. She nodded and smiled more. I kissed her forehead as she hummed. She hugged me tighter and soon we let go. Her face was blank again. Her eyes turned dull and lifeless. I grit my teeth. If the accident never happened, would she still be happy and cheerful like before?

Normal P.O.V.

"This is bad" you stated. "What do you mean, N/n-tan?" the headmaster questioned you. "It was a Basara" you stated bitterly. "I have to strengthen the seal around the island, it'll probably take about 3 days" you closed your eyes and activated your Overload. "Everything is back to normal, I'll be on the mountain, strengthening the seal" you stated. Jin wrapped an arm around your waist and cupped your face. "I'll visit you, alright?" Jin told you. You nodded as Jin kissed your forehead, making your heart feel warm. Jin let go as you smiled at him. You flicked your finger and your katana got dissapeared. "I'll be going now"

Three days passed and the seal got 10x more stronger. Jin visited you as promised. He would bring you food, water and sometime takes turns with you while you take a bath. You were now on top of the mountain, a small smile on your face once the seal was finished. You looked at your wrist watch and smiled slightly. "I'm 8 minutes late, a quick bath won't hurt" you mumbled to yourself and ran to the dorms and took a quick bath and changed clothes.

You greeted Ms. Tome and left the dorms, the satchel of your bag around your shoulder. You noticed the gym door open and saw students inside. "An assembly? Atleast I'm not late for class" you muttered under your breath. Once you stepped inside, you saw the headmaster call someone. You blinked at the blue-haired male but you smelled a familiar scent. The scent of your master. You looked at the male on the stage and blinked. "I'll ask him later" you began to walk away, but you then smelled a scent of blood from the male.

You quickly took out your gun, the sound made some students look at your way. And with that, everyone looked at you. Seredy had an innocent smile but his eyes had a glint of mischief. "Who are you? Why do you have the smell of blood on you?" you stated loudly. Seredy smirked and before you knew it, you were on stage, body on the ground, hands pinned behind your back.

"Those eyes" you turned your head to him. Seredy had a look of confusion. "It's the same eyes as Shinsou" with that said you widened your eyes.
