The Next Day
I had just finished asking ALL of the florists in my region if they had seen someone buy roses at certain dates. Of course, those roses were the ones that were left in the crime scenes, and the dates were near the dates of the crimes.
The only information that I got were that a man in a grey suit bought the roses exactly 24 hours before the crimes, but he changed flower shops each time. Well, after he bought a rose from a specific florist, he waited one year before coming back, otherwise there would not be enough of them. That made him impossible to track.
For normal people, that is. For me it was pretty simple, I left an invisible finger in each flower shop I visited, especially the ones that the man hadn't visited before. I also got a copy of each surveillance recording of the shops in which the man had bought a rose.
Now I had a plan, a simple plan. I would wait for the man in the grey suit to buy to rose, I would follow him and see to whom he would give the rose. What could go wrong? Absolutely everything, but it was the best plan I could make.
The only other option I had was to pay them to assassinate myself and try to capture their members, but it was an even worse plan, who in their right mind would employ a legendary assassin group to kill themselves in hope to find them. No one except a novel's protagonist with an overinflated ego and plot armor. Thankfully, I had both, so I was going with this plan.
Nah, just kidding, I had the ego, but definitely not the plot armor.
And the fact that my plan was sh*t didn't mean that I couldn't be damn well prepared, so I had bought a couple of quirks with the fact that they could make themselves invisible (probably) and that they were assassins.
Infrared Vision (234): Allows user to infrared. Pretty self-explanatory, but if I couldn't see the invisible assassins normally, I would see their heat. Also, it worked with finger eyes so that was a plus.
Instant Reflexes (135): Improves user's reflexes. Scaling with quirk levels spent. Yes, I hadn't paid a lot for this quirk, but even with only 135 quirk levels, my reflexes were nearly three times as fast as before, and I already had extremely good reflexes. So now I had some kinds of impossibly fast reflexes. Also, I could upgrade it in the future if needed.
Those quirks would help me a lot against assassins, Heat Vision to see them and Instant Reflexes if they even managed to surprise me or launch a sneak attack at me, which was highly unlikely, but you never know, and I don't want to die because I was overconfident.
Finally, I had bought a quirk that I realized I really needed, which was:
Unbreakable Bones (485): Improves user's bones toughness and resilience. No, it didn't make my bones unbreakable, but it made them nearly ten times harder than before, so it wasn't bad. Now, I could throw All Might strength punches with my only worry being running out of stockpiled energy, which would happen pretty quickly because those punches took a sh*tload of energy to throw. Also, it would be very useful for my future plans.
The only problem was that, once again, I was completely broke…Only 1 quirk level remaining.
1 week later
After 1 week of watching florists during ALL of my free, the man in the grey suit finally made his move. It was the most boring week of my life, seriously, I was starting to consider plan B, which was the suicidal plan, but I must admit that I am now a specialist of flowers.
The man bought a flower, a white rose this time, which signifying innocence. Quite ironic, I must admit. Still, as soon as he bought it, I left school saying there was an emergency at home as an excuse, and started to follow the man, one kilometer away from him so that he wouldn't spot me. I had a finger spy following him closely anyway.
After walking for a kilometer, he took the bus for ten or so minutes, and entered a warehouse, after verifying that no one was following him. Of course, he didn't see my invisible finger, that was following him inside the warehouse.
The man in the grey suit then simply left the rose inside a vase that was already there, before leaving.
Even though I knew it was useless, I still sent another finger to follow him.
I waited for 7 hours before something happened. The rose disappeared. I activated heat vision and realized, unsurprisingly, that there was someone invisible with the rose in his left hand.
Immediately after I started to see him, I used an invisible finger to knock him out cold, which worked perfectly. After that, I warped into the room and immediately used quirk vision to know what is quirk was, not yet dropping my guard.
Blades (867): User can turn any part of their body into blades.
Well, that was a useful quirk for an assassin, there was no denying it, but it was useless against me. There were cameras inside the warehouse, but, as paranoiac as I am, I had already hacked them.
Now, I only had one thing left to do, and I needed to do it quickly, before The Invisible Rose learned that one of their members had been kidnapped.
I needed to get information out of him, and I had to perfect contacts for this.
First, I asked Giran to help me contact an interrogator going by the name of Nightmare. He was famous for getting answers out of everyone, not matter how strong mentally. Also, he never used physical torture, his means were unknown, but they probably had a link with his nickname.
I said I wanted him to "meet" someone and get them to talk tonight, inside a specific warehouse that I had bought, at 11 PM. I told him it was high priority and that I would pay 5 times his usual price.
As expected, he quickly agreed, money was a powerful motivator.
This wasn't my favourite way of getting information, I much preferred investigating and not destroying the sanity of people in the process, but I really was in a bind right now, as I didn't have much time before the invisible rose realized something was wrong. I was certain that tomorrow morning, they would know that I had caught their assassin, so I needed to be fast.
Secondly, I texted Detective Tsukauchi, using Knockout's account, telling him to meet me at the same warehouse one hour after Nightmare, at midnight. I didn't want someone working with the police meeting Nightmare after all.
He answered me with the obvious, "How do I know this isn't a trap?", so I replied by texting him his address and personal information, saying that if I wanted to capture him, I could've done so a long time ago.
The reason I had asked for him to meet me was that he had a very useful quirk, Lie Detector, which allowed him to know if someone was lying if he was touching them. The only weakness was that, if the person was convinced they were telling the truth, it wouldn't be perceived as a lie by his quirk, even if it was one. I wanted him to confirm that the villain was going to tell the truth when he was going to get interrogated.
Now that all the pieces were in place, I only needed to wait, because today's night was going to be explosive.
