One for All, you say?
A hero for everyone? Becoming the greatest? Being strong? Loyal admirers? Having friends and rivals alike? Happiness?
Child's play.
This name I bear...this ache...this memory. My name, my identity. Ah, how I love it so much. Like how I love my precious Bakugou so dearly...after all, he's the one who made this happen.
I admit, the villain life can get...hectic, sometimes. But my underlings, those people who side with me, they're all here, and I don't need to be some flashy hero to get what I want. I still respect All Might to this day, but sorry, I've chosen this path for myself.
Speaking of siding, villains are meant to fight authority, right? The oppressors? The people who don't understand? Without strong villains, the world will not see revolution. That's why I picked the weak to be with me, preying on them, but ultimately falling in love with their desires...and making those wishes a part of me as well, and we strengthen.
I know Shouto's wishes are mine now, too.
Now I ask again, do you still think this is One for All?
Haha.
No, my darling, let me tell you just one thing.
This.
This, is All for One.
For me.
For this sinister heart of mine, that beats to surpass heroes and villains alike...to surpass anyone breathing on this earth of mine...this...earth of mine, where I'm on the throne, looking down instead of up. I will be better. I will be stronger. I will be ultimate.
Aren't villains just heroes of their own terms?
Then let's have some fun tonight...let me be a hero, by being a villain that all can fight in unison, in fair game, with fair play, and we'll see those sparks of hopes of victory fade away into despair.
The world will be united by this idea, either that or they'll unite when an uprising is staged against me. Who knows, right? But in the end, the heroes are the villans.
So let's just enjoy tonight, alright? Please have some tea. Let me tell you a story of the past, and my path to a heroically villainous throne.
Kanda Kyoichi transmigrated to Konoha and became a temporary instructor at the Ninja Academy. Fortunately, he awakened the Mentor System.
By teaching others, he could earn rewards.
Thus began Kyoichi's career as a "teacher" in the ninja world.
Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!"
Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!"
Kakashi: "He's my life mentor. He transformed Konoha!"
...
Years later, in the memoirs of Kyoichi, now the Hokage, he wrote:
"I honestly just wanted to be a life mentor!"
