By the age of 5, he had already reached his mental peak, possessing profound understanding of the world and remarkable self-awareness. Notably, he excelled academically, earning exceptional grades, with the entrance exam for Constant Magic Academy being notoriously difficult, yet he effortlessly passed. Akuto's combat prowess and magical aptitude were equally impressive, keeping pace with Junko, a ninja-in-training, shortly after joining the school. He even defeated multiple ninjas simultaneously without breaking a sweat. His exceptional memory allowed him to learn healing and complex illusions with ease, and he mastered Hua Jin, a fighting style that took others years to master, granting him muscle control and defensive abilities.**

Awakened: After Awakening, Akuto gained access to Life Logs, enabling him to perceive and select moments from a person's entire life, extracting valuable information. He can delve into the thoughts, intentions, and ideals of individuals, leaving nothing hidden from him. However, he respects privacy and refrains from prying into intimate aspects of others' lives.

Genius: Akuto's combat skills span various ranges, excelling in close-quarters combat and long-range engagements. While he typically restrains himself to avoid causing harm, he can exhibit a cruel streak, utilizing mana in the environment to torture opponents by breaking their limbs. In swift moments, he can apply intense pressure with mana to swiftly end fights, as demonstrated against Boichiro in Act 5.

* **Hua Jin:** Akuto has honed his mastery of Hua Jin, a martial art style acquired from The Principal. Through this discipline, Akuto gains unparalleled control over each muscle in his body.

This combat technique also enables Akuto to skillfully deflect incoming attacks, adeptly avoiding vital areas, as witnessed in his confrontation with Boichiro.
* **Immortality:** Despite Brave's relentless attempts to alter the past and avert the world's destruction, Akuto's immortality remains steadfast. The Law of Identity governs their fates, ensuring that history realigns itself, regardless of changes made in the past. Even if slain in the mortal realm, Akuto can be revived by others, as demonstrated in Act 8. The Law of Identity thwarts his attempts to erase himself in the afterlife, as such an ending is not permitted. Ultimately, killing Akuto or manipulating his afterlife existence bears no impact on his or the world's destiny. The Law of Identity safeguards against any action that would obliterate his afterlife self.

Akuto possesses the extraordinary ability to craft an infinite array of narratives, encompassing diverse concepts, dimensions, and the presence or absence of occult forces. These stories, including those within stories, are known as tales of higher story density, forming an intricate web of infinite hierarchies.
* **Void Body:** The state of Void Body is attained through the final ritual involving the Law of Identity. This ritual nullifies both Akuto's physical form and the souls within him, giving rise to a void.
