The Ultimate Mastermind Detective // Mastermind! Shuichi x Reader

IM THE MASTERMIND!!!

Shuichi's POV

"Im the MASTERMIND!!!" I shouted. Finally~!

"Shuichi... your... your the mastermind!?" Maki said in disbelief, i grinned. "Why of course, miss ultimate assassin~!" I mocked, she looked away. "Nyeh... the ultimate detective was the mastermind the whole time!" Himiko shouted.

"Why!? Out of all people, its you Shuichi!?" Himiko shouted right at me, i just laughed. "You dont have to ask! " i said as i held onto monokuma and played with his ears.

"Sh-shuichi..." i heard Y/N say my name, i looked at her and smiled sweetly. "Yes my love~?" I said, everyone turned to me in shock. "L-love...!?" Y/N repeated what i said to her.

"Yes, got a problem, my love?" I said, i stepped out of the podium and walked towards Y/N's. "N-no... st-stay away... i dont w-wanna g-go near you..." she said, i kept walking towards her. "Hey! Shd said get away! Do you wanna die!?" Maki threatened me, but i only laughed. "Like that can scare me! Im not the Shuichi Saihara that you all knew!!" I said to them.

"But still get away from Y/N! Why did you plan this killing game anyways!" Kiibo asked me, and i smirked. "Glad you asked Robot~! Well you see, i plan this killing game because this game is the most popular game in history!" I explained to them. "Many people ENJOYED the killing game! They want MORE!" I said to them.

"People...? But i thought the outside world is gone!" Tsumugi said, i laughed at their stupidity to think that the outside was really gone. "Nyeh... what are you laughing at..?" Himiko asked. "Hahha, nothing, just saying, i put up thos game for people to be entertained with killing and murder!" I said to them.

"But why do we have to do their entertainment!? Why are they letting us suffer!?" Tsumugi whined. "Because killing, blaming, accusing is most fun! Just watching despair fill all of the participants in every killing game!! Ah~! Dont you just love it?" I said to them, then i laughed.

"But thats not the only reason i want this killing game..." i said as i had my poker face in this time. "Huh? Why?" Kiibo asked. I giggled a bit. "My other reason its because..." i snapped my fingers and the whole room went dark.

"Nyeh!? Why'd you turn the light off!" Himiko whined. Then i turned it back on to let them see my other reason.

I had my hands wrapped around Y/N and rested my head on her shoulder as she tremble from my touch. "Is for me to have my lovely Y/N dear..." i said coldly, i smirked. "M-me...?" Y/N said. "You made this game... to get Y/N love as well!!" Maki shouted at me. I giggled "its quite easy you know... just gain her trust, then in the end ill handle the rest... for our relationship..." i said as hugged Y/N more.

"You really thinks she'll like you when she knows that your a Mastermind?" Tsumugi said, i gave her a glare. "I know... thats why ill handle it.." i said to her.

"L-like y-you can d-do th-that...ill g-get e-executed a-anyways..." Y/N said as she trembled from my touch. "Oh, but did you forget... there will be 2 survivors in the game...and those survivors is us, my love..." I said to her.

"Wh-what...!?" Y/N was not convinced. "Nyeh!! When did that rule applied!?" "Since i said so..." i said.

"Welp... im now bored, lets get into the fun part shall we~?" I aaid with a wide grin spread across my face. "N-no... please... dont k-kill them..." Y/N pleaded, its so cute~

"Im sorry~ but rules... are rules~" i said to her then i giggled a bit, i reached for the pocket in my shirt and took out a red button.

"Dont you even dare!" Maki shouted. "Ill never forgive you after what youve done with everyone!" She said, i giggled. "Aw~ is miss assassin mad because i executed her boyfriend~?" I mocked her, her eyes widened and looked away.

"Nyeh... same here! Tenko and Angie died because of you!" Himiko shouted, i grinned. "Like i can let those annoying girls survive..." i said, Himiko was surprised and started crying.

"Anyways... shouldnt we start? The viewers are waiting~!" I said as i held up the red button. "Dont... dont..." Y/N said softly, i hugged her more. "Its alright Y/N, front row seat to watch their execution is all yours Y/N... then we'll be together..." I said to her.

"Arent you just gonna suffer her more..!" Tsumugi shouted, i ignored her. "Lets give it everything weve got...." i said.

Himiko cried, Maki looked away, Tsumugi pleading to stop and Kiibo looking down, while Y/N trembled and tried to stop me. "Its PUNISHMENT TIME!!! AH-HAHAHAHA!!!" I laughrd minaicaly and pressed the red button.

"N-no! Please n-no!!" Y/N struggled from me as the collars took the 4 away and started their execution. "Shhh... dont struggle... your mine after these bastards get what the viewers need..." i said to her, she kept squirming.

~~~

Maki's execution was first: 'Orphan Assassin', then its followed by Himiko's execution: 'underwater escape trick', then by Tsumugi's: 'Copycat', then by Kiibo: 'junk destruction'

After the execution, i let go of Y/N who's frozen in place after witnessing them die right in front of her. "Congratulations Y/N... you and i are the survivors of this 53rd killing game..." i whispered unto her ear, then i took out my syringe and injected her with the sleeping dose.

"Your mine... your... your finally mine~! Ah~!"

Y/N's POV

I slowly opened my eyes and see nothing but a blank cieling. "H-huh...?" I was confused then i slowly sat up and scanned the room, until i saw him. On the seat and looking at a folder. "Ah morning love, how's your sleep?" Shuichi asked. I backed away not answering his question.

Then he stood up and walked up to me. "Aw cmon, my love~ answer me~.." he said and suddenly held me by my shoulder. I flinched. "Stay a-away.... y-you murderer... i-i hate y-you...!" I tried to protest but my fright would give Shuichi more satisfaction. "I know you dont mean that... want something to eat from the dining hall?" He asked me. "I-i can go there b-by myself..." i said as i took the blankets off, only to be greeted something.

My ankle has been cuffed to bed! I looked at Shuichi who has a smirk in his face. "Im not letting you go Y/N... after all, you are mine..." he said as he pulled me into a hug. I tremble by his touch. "D-dont touch m-me... you k-killed them..." i said to him, he chuckled. "I did... and im happy..!" He hummed.

"Ill make you love me Y/N... just you wait..." he whispered to my ear.

No... ill still hate you... nothing can change that...

A/N: mastermind revealed boom! But its not the end yet~! Were getting the love ending here! >:3
