Good guy bad girl(DTK x reader)

School with a very cool grim reaper

Kid's pro
I watch the class move in as I do I notice a girl with long white hair and red eyes. She got pulled to the side by Stein. I watch as she sits next to me. "Hi I'm Death the Kid. You can call me Kid." I say. She smiles. "I'm Storm. Crona's sister." I look at her then Crona. They look nothing alike! Not even their souls! "Hello!" Storm was shaking me. "Oh sorry. But how are you related?" I ask. "We have the same mother. And both have black blood." She list off. I look at her soul once more to find a bit of something else....witch. "Ok class Storm and Crona will come up and show us their black blood weapons." Stein anouced. Storm rolls her eyes and heads to the front of class. When they do Crona has a bit of trouble with Ragnorock. "Listen you stupid black bool do as Crona says." Storm hisses and Ragnorock listens. Storms has a thinner sword and more light weight. "Ok now you can go sit down." He says. Storm comes up and sits again. We go through class and when it's over we head to lunch. "Hey Kid what's up with the stripes." She comments. I look at her almost perfect hair. "Well I'm unsemetrical." She laughs. "Well I like it."

Crona's pro
After school I was running with Storm and Alois the dragon.. "Hurry up!" She called to us.She ended up tripping and falling on her face. "Storm!" I say help her up. "Ow." She groans and looks at her scrape. "Rar!" Alois roars at us. "I'm fine." She smiles and uses her magic to heal the scrape. "Wow." I say to her as it heals completely. "Ya that's what magic can do." We head back to the room. And when we do Miss Marrie was there. "Hey." Storm says and jumps on the bed. "Hello Storm. I was here to get you. Your moving to a new apartment!" She cheers. Storm frowns. "What about Crona. I'll never leave him alone again." I smile at that. "Well he is supposed to stay here under order of Lord Death for betrayal." Miss Marrie says. "Then I'm staying right here." Storm lays down and then Miss Marie sighs. "I'll talk to Lord Death about it." She walks back and I sit with Storm. "Did you mean it? About never leavening me?" I ask. She nods. "Ya stupid. I'm nothing gonna leave you again." She smiles. After a few minutes Miss Marrie comes back. "Lord Death okayd it. But it right next to Kid so if anything happens." She smiles. We get our things and head to our new apartment! Storm doesn't look to pleased. When we arive she sets her things down in one of the rooms. "I'm going to take a nap." She yells and closes the door. I smile and set my stuff down. "What a good day."
