The idea is good, but the development of the story is horrible.

I liked the previous chapters, but I think I could have had more time with them as children.

I'm not fluent in English, I apologize if you hear a lot of mistakes.

I found the plot development too fast, if you want to make a longer fanfic, I recommend you to have longer daily lifespans, read The Devil of Yuragi-sou and anhihilation maker DXD for example. Ps: this is my opinion dare if you want.

he was 16 years old, but he cannot use the basic aspects of his own innate technique.

This fic is bad, because the author didn't know how to balance the power, he's trying to copy the canon even now it's impossible to repeat everything like the original.

if it wasn't for the system, Cell would have killed him without breaking a sweat.

I looked for it, but I didn't find it, it may not even be the original name.

Do you know who the original author of the story is?

Is the story yours, or do you just translate?

the protagonist has a magical basement to train every day, even so he is weaker than his sister.

it does not produce an aim field, nor has it absorbed telesma in order to awaken.

the plot is escalating to something terrible, no offense but what will super strength do against vector control.

my senses of putting this story down are tingling.

he's a level 3, accelerator with less than half the brain power continued as the strongest of the levels 5.

vector manipulation, works in a more conceptual way, ignoring the difference in power, so even if it was a universe-destroying punch it would be redirected, as long as it was calculated.

I understand Kobeni, but I don't see Power getting into a relationship, for me that's the same thing as the last order dating Accelerator, well that's my opinion.

At the end of the Devil of Eternity arc, Himeno forms an alliance with Denji, in which she would help him stay with Makima if he helps her stay with Aki.

Himeno likes Aki, I find her and Denji strange, I can't see Makima loving anyone, and Reze matches better.
