(Diabolik Lovers) Yandere! Reiji x Reader Maddness
Reiji never understood why she gave Kanato so much attention. He’s an abusive, reckless, bipolar, spoiled brat; even though Reiji was sadistic himself. But that’s not the point. Kanato always wants and clearly enjoys (Y/n). Reiji was baking a batch of cupcakes, 1 out of the 6 of them was poisoned that could kill anything that it consumed it even vampires. He well knew Kanato couldn’t resist sweets. It was almost like an entertainment to Reiji because he’ll never know when Kanato will eat that poisonous cupcake. Each day he would have one but much to Reiji’s disliking it didn’t happen…yet. A few days later it was down to the last cupcake. The fate of death waited for Kanato Sakamaki. During the time being Reiji was waiting near the kitchen eagerly to see Kanato in his final moments. He heard someone rummaging in the room, deciding to act innocent Reiji entered.
There was one thing he forgot…
“Oh good evening.” (Y/n) said warmly to him while taking small bites into the cupcake.
(Y/n) likes sweets as well.
He ran up to her and threw the cupcake away, it was half gone, “Why are you eating dessert before your dinner!?” He didn’t want to alarm her about what she ate.
She got startled, usually Reiji isn’t this mad about eating before din din, “I-I’m sorry Reiji! I was really hungry…” (Y/n)’s tone of voice seemed off.
Damn it! The poison is already in effect!
“Hey! What’s wrong with (Y/n)?”
Damn it! Now Kanato decides to come?!
“Nothing! Now may I ask what’s your business here?”
Kanato immediately got fired up, “I sensed there was something off with her!” (Y/n) collapsed right when he said that, Kanato was by her side instantly, now holding her limp form in his arms, “WHAT DID YOU DO TO HER!?!?” Tears spilled from his furious eyes.
Reiji’s straight composure didn’t leave. He knew that he killed (Y/n) and if Kanato finds out he’ll kill him.
“ANSWER ME NOW!!” He slammed his fist on the floor.
Reiji smile sadistically, knowing he’s much stronger than him, “She’s dead. That cupcake she ate contained the highest amount of poison that can kill anything. And it was made specially for you.”
Kanato screamed at the top of his lungs, stood up and charged at him. There was too much of a ruckus that would draw unwanted attention from his other brothers; looks like he’ll have to kill him even though that was his goal anyway. He slapped Kanato across the face then kicked him in the stomach causing him to slam against the wall. Kanato wanted (Y/n) back. He wanted his revenge.
Attempting to get on his feet, Reiji wasn’t going to give his younger brother the chance. He reached into the inner breast pocket of his coat, pulling out a needle that had the same poison that (Y/n) took and injected it into Kanato’s heart. This was a stronger dose. Blood came out of his mouth, spilling all over Reiji’s clothing. He tried to reach for his throat but his arm dropped and his body went limp. Reiji slipped out a couple of snickers. After taking a minute to himself, he picked up Kanato and (Y/n)’s bodies and teleported to the dungeon. After that day, Reiji strictly forbade his brothers to never go down there. His brothers knew what happened but they made the decision to not say anything or even hint at it. Yes they were enraged that he killed their bride (Y/n) and a bit on Kanato’s part, they made a plan on getting revenge. Yes…but they’re saving that for later on. But in the meanwhile they watched their own brother slowly turn mad.
