A Villain Reborn A Devil
King is gathering fruits and vegetables from the forest alone. While he was doing so he stops and remembers the time when Meliodas and Ban went missing and when Merlin disappeared from the room. "Where are you guys?" he thinks to himself. He collects the rest of the fruits and flies back to the tavern. There he sees a giant stack of dead animals. "What the hell is this?!" King shouts in shock. Behind the stack appeared Rimuru. "Oh King. I got us all lunch." Rimuru replies. King is really confused but smiles and awkwardly laughs then Rose appeared from behind the stack. "Uncle Rimuru! I caught another one!" she yells with excitement while holding a dead rabbit. "Good job Rose!" Rimuru praises and pats her head. "Just put it on the stack. We'll bring it all in later." he adds. She nods and throws the rabbit in the stack before running inside the tavern. "She's been speaking better and better every day." King says. "Guess she's a fast learner." Rimuru replies.
They both start to smile. "Come on let's bring it all inside." Rimuru says. King nods and they bring everything inside. They placed it all on the counter and turned to see Elizabeth carrying and playing with Rose near another table. They look at her for a moment before smiling and walking towards them. "How's everyone doing over here?" Rimuru asks. Elizabeth turns to them while smiling. "We're okay. Did you get all the food?" Elizabeth asks back and Rimuru smiles. "Yup." he replies while pointing to the stack behind him. Elizabeth looks at the stack with shock. "Oh my! there's so much." Elizabeth says. "Hehe. Don't worry about it." Rimuru replies.
Suddenly Rose runs over and jumps into Gowther's arms. "Gowther let's play!" Rose asks with a laugh and smile that infected everyone around her. "Calm down Rose. We'll play after we eat." Gowther replies. Rose got upset and starts to pout. "I wanna play first! Let's play!" Rose asks more loudly. They then hear Elaine calling Rose. They all turn to see Elaine at the stairs. "Now now Rose. If you don't behave you won't get to play." Elaine says. Rose looks at her with a sad look on her face. "but I wanna play." she replies in a low voice. "You can play after we eat. I and Elizabeth will finish lunch until then just wait for a bit alright?" she says. Rose pouts again before replying. "Okay."
"She's quite the handful isn't she." Rimuru says. King looks at them with a smile. "I wish the others were here to enjoy this." King replies. Rimuru looks at King before looking at everyone. "We'll get them back so they can enjoy this as well." Rimuru reassures.
A man walks into a room where he sees Professor Mab doing something on his desk. "Excuse me, professor?" the man asks. Mab turns to look at the man. "Ah yes, what's the matter?" Mab asks. "One For All has returned and has asked for your presence." the man replies. Mab sighs before standing up. "Where is he?" Mab asks. The man tells him where he is and Mab rushes out the door and heads to the medical station. He opens the doors and see's an injured Toshinori on the medical bed. "What happened?!" Mab asks. Toshinori didn't say a word but instead began to laugh and his laugh became more maniacal before he calmed himself down. He stuck out his arm to Mab when suddenly lightning began to surround his arm and then his whole body. He curls his hand into a fist before responding with a grin. "I've taken back what is mine." Toshinori replied.
Mab began to smile as well and started laughing with joy. "You did it!" Mab says. Toshinori tried to move but felt a sharp pain in his abdomen and stops, his smile now gone. "Professor, get me started on that Upgraded Demon's Blood." Toshinori says. Mab looks at Toshinori with shock before responding. "That blood is too dangerous to be given to you. If your body can't handle it you'll die immediately!" Mab replies. Toshinori forces himself off the bed and stands up. "I could care less. If some measely old men could injure me to this degree then I must get stronger." Toshinori replies. "But this blood isn't the same. It's far more powerful and dangerous to-" Mab interjects but was cut off by Toshinori. "I want it Because it's more powerful. I wasn't asking you either. That was an order and I expect you to follow without further intervention." Toshinori says before walking out of the room. Mab slams his hand on a table. "That foolish little-!" he says to himself before calming down and walking out of the room. He walks towards his lab to which he finds Toshinori about to enter the door. "Perfect let's begin." Toshinori said before opening the door and walking in and Mab following shortly after.
Toshinori lays down on the bed and Mab began collecting everything necessary to begin the injection. He collects everything and prepares the Upgraded Demon's Blood in the syringe before walking up to Toshinori. "This is your last chance to end this." Mab says but without hesitation, Toshinori responds. "Do it."
Mab injects the blood into Toshinori and he began screaming in pain, his body strapped to the table and the straps barely holding him down. One For All suddenly activates. This time with black lightning surrounding him. Toshinori still screaming in agony breaks through the straps and Mab runs out of the room leaving him inside. He rushes out and he could still hear Toshinori''s screams when the building suddenly shakes and everything went quiet. Mab can no longer hear Toshinori scream. He slowly walks up to the room he was in and when he arrived found blood flowing out of the room's door. He feels a large weight of fear and nervousness but forces himself to open the door and to his horror, the room was filled with blood and in the center appears to be what looks like a giant heart attached to the room.
He walks away and puts on some safety equipment before returning to the room and collecting samples of blood and parts of the large heart for research purposes. As he began to collect a sample from the heart he could feel vibrations coming from inside. He brings himself closer when suddenly an arm ripped out of the heart and grabbed Mab's neck. Toshinori proceeds to rip himself out of the heart and walks out and see's Mab. Mab is shocked to see Toshinori with White hair, a black and red left eye, a pure white right eye, grey skin, black arms and legs, and horns on his head, and a line of black marks surrounding his whole body. Toshinori begins to laugh maniacally before letting go of Mab.
"Professor it worked! I feel incredible!" Toshinori says. Mab quickly tries to collect his words. "I-I can't believe it worked. I was sure you would be dead." Mab replies. Toshinori laughs even more maniacally. "I must test this power! with this, I'm sure I can bring many worlds to its knees!" Toshinori yells with excitement. "One For All." Mab says. Toshinori turns to Mab. "What is it, professor?" Toshinori asks. "There's something else I would like to show you. Another experiment I have been working on. It should be useful to allow you to test your newfound power." Mab replies. Toshinori's smile grows even wider before replying. "Show me."
They headed to the training grounds and to which Mab calls out to someone and suddenly 3 girls with a similar look to Rose appeared. "What are they?" Toshinori asks. "My special weapon. They are equipped with something that may be of use to you." Mab replies. Toshinori walks forward. "Let's see what they can do." Toshinori replies. All three girls rushed him and attacked him but Toshinori found them to be incredibly slow. He easily blocked their attacks and threw them all away. "Professor, If this is your latest experiment then I'm very disappointed." Toshinori says when suddenly Mab began laughing hysterically. "Alright girls. Let him have it." Mab said. Suddenly all the girls had lightning surrounding them similar to One For All. They jumped him and this time they were so fast Toshinori could barely dodge. "One For All?!" Toshinori thinks to himself. All three of them attacked simultaneously and pushed Toshinori back significantly. Toshinori began to smile before asking. "What did you do to these crazy girls professor?" Toshinori asks. "This is the one of the few of their kind. The first-ever to have an artificial quirk and as for what those quirks are...well you've already figured it out haven't you?" Mab responds with a grin. "How many percent can they use?" Toshinori asks. "As for now they can handle 1000% just fine but if they push it can reach 1 million but that's where their bodies will give out." Mab replies.
"This is going to be fun."
