The_Essence_
Dude, you literally copied my thoughts! In my free time, I often thought about the concept of reincarnation into Neito Monoma. I'm so glad someone turned my fantasies into fanfiction! P.S. Have you read the spin-off MHA:Vigilantes? There was a villain with an interesting quirk that would allow him to further accelerate the accumulation of OFA's power. I think that it will not be able to accumulate more energy in seven years than OFA in 100 years. P. P. S. MC is too focused on OFA. The only quirks he needs to defeat AFO and Shigaraki are Twice's and Aizawa's. Imagine 1000 Todoroki burning Shigaraki until he can't use his quirks.
I meant the main villain of MHA:Vigilantes. His name is Number 6 or Nomura. One of his quirks is called Overclock. It allows the owner's body and thoughts to accelerate while his brain receives enough oxygen. Overclock can also speed up the owner's quirks. For example, using Overclock you can speed up the Regeneration quirk, which will lead to instant healing of wounds. The weaknesses of this quirk are brain injuries. Any hit to the head will prevent you from using Overclock normally. Another weakness is the short usage time: 2 seconds every 10 seconds. But this weakness can be overcome if the brain is supplied with enough oxygen.
The_Essence_:You can’t really blame the MC for being so focused on OFA currently. Midoriya proved that all you need to beat Shigaraki or atleast have a fighting chance against him, is to just have OFA. Based on that, it’s understandable why he would be so fixated on OFA now. If he eventually manages to gain OFA, then you’ll see if his behavior changes or not. Also, who is this character you mention. I’ve checked and I can’t find him or her.image
