I’ll give you some of the best of my thoughts — as One For All. Because it would ease me to teach something to my children. Because civilization is sustained by its norms. So the higher the norms, the easier it will get for me to teach the children how to fly.
It might sound too philosophical, so you probably would refrain from absorbing them. But that's the idea.
And it might not be in its best forms, because my current knowledge and language is limited. But that’s also what makes it perfect.
I’ll give it to you now, and you will have to pass them down — here what you got by mixing them, fusing them with yourself, to the next generation of heroes. Or you can just pass anything. It doesn’t matter, as long as you pass something down, right.
But I’m not sure you could pass anything new without it. So I guess mastering them is the only way.
Deal with it.
You got your One For All, now you're officially Pro Hero.
