Izuku's POV
I was walking around and I felt a presence of a person I smirked and said " I know you're there , so come out." he went out and asked "How did you know I was here?" he was so rude but I used my siren quirk and said "Since you are the one following me I will be asking the questions ok." he opened his mouth to say something but he didn't he just had a slight blush I laughed and asked " so who sent you or was it a teacher?" he looked surprised looks like somebody is after me and since he was under the affect of my truth telling quirk he said "The person that sent me here is Aizawa he said to keep an eye on you." so I smiled 'so it looks like he is catching on.' I put the slave contract on him for second his eyes looked lifeless but, afterwards he asked "What can I do for you young master?" I had a great idea I could have him be a spy from the inside since he won't be suspected or noticed since he is a weak less popular hero and said " Can you be my little spy?" it wasn't really a question more like a demand but I wanted t make him feel like he had a choice he nodded then left after that I kept on walking 'Things are getting interesting.' and left.

After I finished my walk I went to my dorms to see Todoroki waiting for me and he said "Mr.Aizawa wants to see you." I smiled at him and laughed at his adorable reaction then left to see Aizawa he was in his sleeping bag but once he saw me he got out of it I put on fake smile and said "what did you want to talk to me about sensei?" he looked straight at me and used his quirk not knowing he only got rid of my least important one which was to change my ye color to green luckily I put contacts on just in case, I smiled and said "I would like for you to not use my quirk on me." he looked shocked to say the least and before he could ask how did you know I said "Well I knew your quirk was erase so sometimes I try to make a small gust of wind when your around and when I couldn't it proved me right." he had a blank face and said "I knw your hiding something I will get to the bottom of it." I just smirked and said " I'm looking forward to it." he was speechless.
I left to get a shower, put on my disguise, and go to kill All Might since I wanted to have fun with Aizawa I made it to his house he has a lot of security I used my super speed to get the first three with a quirk I made to make my nails sharper, longer, and way more endurable With the other hundred I just used my soul taker quirk it takes their souls and make me more powerful 'I love using this quirk.' after that I went to All Might looks like he was already informed so I made an injection so h could be really sensitive to pain to make him easier to kill I kept on giving him scars afterwards I stabbed him multiple times but left him alive while teleporting a note that said 'if you want to save all might come to **************7008***8*.' it was a "abandoned" hotel.
Aizawa POV
I saw a note appear on my desk I looked at it what was written on it frightened and shocked me to the core I had to save All might and when I got to the place there was a note it said 'play doctor get the ticking time bomb' I was looking for the time bomb to hear a ticking and see Toshi's motionless there was a knife right by him so I cut his stomach open with caution because if I didn't he could die from blood loss and saw a bomb I froze in disbelief 'How cruel' I had looked at it to see it had 2 minutes left I opened the bomb trying to figure out how to shut it down it only had 30 seconds left I tried and tried until I shut it down I sighed and then saw that All Might wasn't breathing. I heard a laugh and looked up it was a big tv a person with long silver hair had said "Did you like my surprise?" I responded by saying "why did you do this? who are you?" he frowned then smiled and said "I did it because I can and who I am I'm sad you don't remember me." but he shifted he had green hair and eyes the traitor was Izuku Midoriya he left with a final laugh.

Shigaraki's POV
I was watching TV when suddenly it turned onto the new by itself it said "Tonight at 9:30 PM All Might was found dead at his house the heroes said it's a new villian from the LOV I will now pass it on to Ms. Petra." I smiled 'That's interesting I wonder who did it.' after that I heard a knock when I saw who it was I got happier it was Jiyū he smirked and said "Are you happy with the news, also what took you so much effort to kill him? He was so weak." I was shocked to say the least he was the one that killed him I had to ask "So how did you do it, and who are you really?" then I saw a change in his appearance he now had green fluffy hair with red eyes he looked just like one of the students 'it can't be?' he said "Let me formally introduce myself I am Izuku Midoriya from class 1-A number 1 villian that killed All Might." he was smiling I ran and hugged him if it was anybody else in the LOV I would make them decay but I was happy since it was him but I stopped 'but what's his actual quirk' so I asked "what is your quirks?" he smiled and said " My first one it reaper, my second one elementals, and the last one is copy." I was rendered speechless once again..
Izuku's POV
Once I was finished with shigaraki I left and got in U.A. with my invisibility quirk to see people going to the multi-purpose room and saw Aizawa he said to everybody in the school "As you all have heard All Might was killed and also I know who the traitor is it is Izuku Midoriya." when class !-A heard this they broke down Todoroki acted surprised but a flash of relief washed over his face but I to talk to him telepathy style and said "You are4 not the only traitor there but I will be watching from the shadows." I then shot Aizawa and the last thing he said was "Truth be told I suspected you from the beginning." everyone looked shocked while the teachers got in battle stance I said "this is my announcement of war on heroes." and left.
