One Hell of a Girl (Ciel x Reader)

Undertaker (Part One)

You were running towards Ciel's mansion, when you saw Claud chasing you. He tried to grab you but ended up ripping some of the skirt part of your dress. You ripped the rest of your dress leaving you in the top and black booty shorts, like Alois's. You started to fight Claud, you managed to get him on the floor you put your knee on his back and twisted his arm. "Tell Alois I'm not interested!" You screamed at him. He nodded and started to let out a few tears of pain. You let go of him and he ran back to his master. "Well, Well. I think I underestimated you to be a weak human." Sebastian said jumping off the tree he was watching you and Claud fight. You then notice Suzo jump right behind Sebastian. "Michaelis. I win the bet. She took Claud out with no problem" he said and gave you a high-five. "Bassy! I'll take you on any day in a hand combat dual!" You said sorta imitating Grell. Sebastian looked at you mad that you were imitating Grell. You walk in the mansion to see Ciel standing in the stairs. "Sebastian where were yo-" he stopped talking as he saw you with the half of your dress on and booty shorts. He stared at you and said "what happened to you?". "Young master, y/n got into a fight with Trancy and ended their engagement. Then Claud chased her and she sorta... Beat him up." Sebastian explained. Ciel dropped his jaw and said. "Y-you took out Claud! But but your only 13 and, Human!" He said surprised. "Ciel I can take Sebastian out to. You want me to show you." You said. "Sure.." He responded unsure. You walked to your room and put on a black top. Then you walked to the garden to see Ciel and Suzo sitting down waiting for you two to start fighting. "Begin" Suzo said. You stood there as Sebastian threw knifes at you. "Sebastian stop!" Ciel said scared that you would get hurt, but to his surprise you caught all of them. Everyone's jaw dropped, including Suzo's. You threw them back hitting Sebastian with all of them. He was pined to the ground as you looked at him. Then turned around and bowed to the audience. "How?" Ciel asked, "Sebastian is she human". "As human as you are Master." Attempting to get the knifes off him. "He let you win!" Ciel said. "Actually young master if you don't mind close your eyes I want to go a little harder on her" Sebastian said. "Fine but don't kill her!" Ciel said and closed his eyes. Sebastian turned into his ultimate demon form. "My my, Sebastian you are sure beautiful." You said. He started to fight you and you fought back. He threw a knife at you and you caught it and threw it back him. He got tired but you didn't. "Ciel it's over" you said. He open to see Sebastian on the floor panting and black feathers all around. "Y/n can I give you a quick cut" Sebastian asked. "Sure" you said. Ciel had no words at the sight of his butler being defeated by a 13 year old girl. "That's what I thought." Sebastian said. "Y/n do you have anyone that is part of your family" he asked. "Yeah. Why." You asked. "Who." "You may know him as.... The Undertaker" you responded.
