Several Points to remember before reading:
This is an AU of MHA, with different timelines and the MC has no prior knowledge of the world.
The MC is just your average kid, intelligence-wise, learning as he grows, he can and will make mistakes. He is not some super genius or perfect in any way.
Since this is an AU, do not freak out when certain things are changed, like times, ages, etc. of characters, people, or events.
This will also be decently slow fanfic, which you will see as you read, but keep that in mind.
I will try to keep this in only the MC's point of view the entire time, only maybe switching views for plot purposes. So expect to not know what is happening outside the knowledge of the MC, because if the MC doesn't know something then you won't either.
There is going to be character growth and development, but don't expect it to happen overnight.
