Over time it took my a while but after two weeks I hand finally put HK and T3 into working condition not quite prime but with them on they can fix the rest of the damage to each other. I also removed the pacifist package I kept in HK, it didn't inhibit his speech or thought but prevented him from harming any humans and now that it is gone he can kill as much as he pleases.
When HK learned of my situation he was righteously furious wishing to terminate he meatbags who harmed his master but I told him our revenge will wait for the right time and be quick. T3 showed his support even refrained from arguing with HK as they supported me and helped to repurpose a lot of tech to make them blasters and other weapons for the two droids to utilize.
After that I had HK act as a inbetween for me and the underground to have a name made for myself taking some work. After the USJ incident there was a little bit of a vacuum in the underground to the sheer amount of grunts that got captured so it wasn't hard to make a quick buck here or there and make connections. The most important one was Giran the info broker who took notice of my movements but had other business at hand as he was trying to set up contact with Hero killer stain.
There was 2 week lull during that time in which I spent it training to my absolute limits with no more school or appearances to keep up I was pushing myself like a man possessed. I got good results as it didn't make a huge leap but what I achieved was a higher degree of mastery over my powers. My adaptable body has combined the source powers from the system with the quirks to finally make them truly mine. To explain it was like the powers and my body were like a wifi router and a computer. The computer can work without wifi but it is more limited but now it is a lan hardwire connection giving me full access to all my capabilities more efficiently all the time.
There I was watching the sports festival in the warehouse from my recliner, thanks to stolen cable, I watched the progress Deku has made with OFA. It seems he went from 8 to 10% and he had the sharingan on now that I'm out of the picture and two people having the exact same quirk would raise questions but there isn't. No one knows or remembers me. Well I think, momo was noticeably sad but didn't know why leaving me hope that I can reverse the Kotoamatsukami but not before killing everyone that wronged me Deku included. From there we can just go to a new timeline or universe.
I settle down as I'm getting worked up, one step at a time. Then I heard a ding in my head [System functionality 100% / system power 5% to peak / Legacy token available for use] "What is a Legacy token?" T3-M4 gives me a weird look as I shift in my seat forgetting to talk in my head [Legacy token is used to select a fictional character's legacy to receive. Legacy tokens are earned from excess soul power gather over time from host or soul power of deceased near host] 'So killing people or waiting?' [Yes, system users are worth more. Progress to next token 1%]
I begin to think about who I should choose since I want a large power boost to help me overwhelm those User assholes. I'm having difficulty picking between Vegeta, Sung Jinwoo, or Dio Brando. Jinwoo would give me access to shadow summons, Vegeta's martial arts could give me insane power but I'm not sure if it will have limits in this universe or be hard to cultivate with my current resources, and Dio would give me his stand Za Worldo to freeze time. They may be powerful but if they can't fight in frozen time. In the end I choose Dio with plans to pick Jinwoo then vegeta for my next two tokens.
[Would host like vampire powers of Dio?] 'No, I don't have a means to combat the sun yet' [integrating memories and base level powers.] I promptly pass out to wake up later with an intense hatred for people surnamed joe star and a stand. I can tell it won't be as powerful without being a vampire or joestar blood but due to my current body makeup and strength I can still cultivate my ability to freeze time up to about 5 seconds. I smile knowing I'm one step closer to my goal of wiping out those assholes if I can use this to its full potential. [System user detected nearby. Recommended to destroy ass soon as possible.] it seems they are here to check up on me. I wondered who the hell was watching this place but since they never caught HK leaving or entering I didn't care till now.
Leaving the warehouse in my Revan outfit I make my way down the street as calmly as possible as I make my way to the local 24/7 stop. It is pretty late so the guy working the register is used to weirdos not caring for my attire as I purchase some snacks and drinks to leave, the whole time my tail watching me. Once back out I keep moving on until I come to the alleyway where he is hiding and stop time using my stand. Being my first time I barely get half a second but I make the most of it using a shushin and getting right behind them. As time resumes they get shocked that I disappeared and look for me running out onto the sidewalk before turning back to the alleyway only to be slammed against the wall.
I remove the mask they wear and peer into their eyes with EMS and read their memories. The information is very helpful with knowledge on their organization and members. She doesn't know anything above her pay grade but it is good enough as I slit her throat and stab her in the heart. I learned that she was a bottom tier system user that got picked up for her expertise in stealth but apparently never ran into a force user before now since apparently pretty much anyone with a system is an otaku and chooses shit like one piece, naruto, bleach, or jojo including her as she bought joestar blood hoping it would give her a stand which I did not.
Lucky for me though as the legacy system can absorb it and give it to me when it takes her soul and system to devour them. [System power 6% / Joestar bloodline gained] I feel my blood growing and it is euphoric as my stand grows with me. I walk out of the alleyway after sealing the corpse away for me to burn later. When I return I find HK waiting with a envelope of cash "Statement: While I do miss the decaying meatbag I like getting out master. I also have a message from Giran that he is interested in meeting my maker." I take the envelope and count the cash and seal it away for later as I tell HK "Set it up to happen after we get news of the hero killer being put captured. It should be soon since the internships should be happening soon."
After that incident and plan I get back to training more specifically my stand as I practice my ability to stop time and get it to a respectable 4 seconds. Things are moving smoothly as Deku enjoys hisself and the Users get antsy since one of theirs has yet to report in from their spy duty. They even come to me seeking to know if I did anything but I play stupid and it isn't like they find anything to prove I did it or am rebelling. I wanted to slaughter them all right there but I have to play it slow and safe as according to the system they still have a couple trump cards I can't overcome just yet.
Once Stain was captured HK set up the meeting with Giran where he showed me the hero killer Stain video to sell me on joining the league of villains. Thinking about how best to destroy this world I look to Giran saying "Sign me up." He gives me that disturbing smile of his and sets me up to join him with the rest.
