> Zero was my messenger, and now he is gone. But thanks to him, the gods are dead. Why? To bring magic to all of you equally. Why did I kill the Empress? To destroy the ruling order of this world. Now, who will you obey? Or will you live for yourself? Choose. The time has come to decide the fate of this world. This is the last war. And I am this world’s last Demon King.

> Now... that means we have to think of what we say to our own higher power in answer. I want to save not just what’s inside me, but everything in the Law of Identity’s universe. I want to free them from their stories. That is my wish.

**Standard Equipment:** None notable

**Intelligence:**

Gifted; Even as a baby, Akuto was serious. When witnessing being left, he looked as if he was brooding his next move. By the age of 5 he already had reached his mental peak, having astute understanding of the world and great self-awareness. This is most notable in academics, having excellent grades. Junko even stated that the entrance exam for Constant Magic Academy is so difficult that there are many years when no one can pass. Akuto also isn't a slouch when it comes to combat and learning magic. He has been able to keep up with Junko, someone training to become a ninja just after enrolling in the school. Later, he even fought several ninjas at the same time with little to no difficulty. At times he even demonstrates excellent memory, learning healing just by seeing it once the day prior, or learning extremely complicated illusions that can predict the opponents moves, make them fearful, and even cause death, just being seeing them. He even learned Hua Jin, a fighting style The Principal needed years to master. This allows Akuto to control every muscle in his body and deflect attacks.

After Awakening Akuto gained access to Life Logs, which allows Akuto to know every single moment of a human's life, being able to pick and choose ones that would benefit him in terms of information. He also knows the very thoughts and even intentions of people when accessing the Life Logs and their ideals. Virtually nothing is hidden from him in this state. However, he isn't the one to pry in someone's intimate parts of their life and allows them to keep their privacy.

**Standard Tactics:** Akuto has shown the ability to fight at different range's, be it close combat or from a distance. Usually, he holds back as to not injure his opponents, however there are moments where he snaps and can become quite cruel, torturing his opponents by breaking their limbs using mana in the surroundings. Or he can quickly end fight by putting pressure with mana, like he did against Boichiro in act 5. He also is familiar with group fights, taking on several bullies, ninjas and soldiers at the same time.

**Weaknesses:** Cannot control how much strength he uses, leading to far worse injuries to his friends and opponents than intended, however there are moments he snaps and becomes good at controlling, and was practically overcome by act 4.

**Notable Attacks/Techniques:**

* **Hua Jin:** A type of martial art or a fighting style that he learned from The Principal. This allows Akuto to control every single muscle in his body. What's more, this fighting style works well with his magic type and because of that he can lift gigantic structures such as the Genkaku, a ship 350m in length. This also allows Akuto to deflect other's attack as to avoid vital spots, like he did in his fight against Boichiro.
* **Immortality:** After the world was destroyed and Akuto arrived in the afterlife Brave attempted to travel into the past to prevent the world's destruction. He attempted this many times by, amongst others, preventing the development of magic and killing Akuto, but when he returned to the afterlife of the future nothing ever noticeably changed. That was due to The Law of Identity having predetermined the fate of Akuto and the world. No matter what Brave changed in the past, history would always realign itself to keep the end result the same. Akuto could, for example, later on be revived by someone else, as demonstrated in Act 8. When Akuto tried to crush the afterlife and by that erase himself, the Law of Identity stopped that as well, as this wasn't an ending it would allow. In conclusion, while one can kill Akuto in the world of the living, sending him to the afterlife and by that winning against him, it will ultimately make no difference for the fate of him or the world. Furthermore, any action that would even destroy his afterlife self would be prevented by The Law of Identity.
* **All Stories:** All of existence is stories. From the inside these stories appear to be truth and from the outside to be fiction. Akuto is capable of creating all stories that can be described. This includes stories with higher dimensions and without, with time and without time, where the occult exists and where it doesn't and all other sorts of different concepts. Some of these stories contain stories themselves and people like Akuto that can freely create stories. These stories can be called stories of higher story density and can form infinite hierarchies.
* **Void Body:** The void body Akuto is a state archived during the final ritual with The Law of Identity. That ritual brought both the stories and Akuto's body down to zero and created a void. During this ritual, Akuto and all souls in him are taken into The Law of Identity and together with it they enter the Anti-Universe, the place where all stories end.

**Note(s):**

* "God Suhara Arc" is a fan-given name for the first arc of the series, which covers volume 1-5, which would be episodes 1-12 for the anime. This is done for the sake of conveniency.
* The "Empress Kazuko Arc" key covers Volumes 6-9. Volume 6 is a slice of life type of story, which can be interpreted as a fun standalone read where the characters are trapped inside of a videogame. Volume 7 revolves around VPS (Virtual Phase Space) and the ending introduces us to new trouble that will revolve around Empress Kazuko and Zero from Volume 8-9.
* "Formless Power Arc" covers Volumes 10-12, with Volume 10 being a more casual read centered around student council but not much happening. This also includes volumes 11-12 which are centered around The One, an alien from an outer universe and his civilization invading the main world which is known as the "Formless Power".
* The Void Body only existed during a very short time during the end of the story and as such not much is known about it.
