Akutsu serves as the director of the Supernatural Phenomena Measures Bureau, a government organization dedicated to managing psychic individuals and paranormal events. He becomes the direct superior of the protagonist, Sasaki, and is entrusted with considerable authority, including the power to hire subordinates and delegate responsibilities within the bureau. His leadership style is pragmatic and focused on results, as he is shown assigning agents to missions, debriefing them on operations, and offering recognition for their contributions, such as when he praises Sasaki and Shizuka for their actions during an attack on bureau headquarters.

Akutsu's personality is complex and marked by a clear-eyed understanding of the espionage-filled world he operates in. He is known for taking extensive counter-espionage measures, which include placing surveillance bugs in the private homes of his own subordinates. When this practice is discovered and leads to an accusation of sexual harassment from a female colleague, he deflects the charge by claiming to be homosexual and therefore not interested in women in that manner. This moment reveals a manipulative and calculating side to his character, willing to use personal statements as tactical tools. Despite the invasive surveillance, he also demonstrates a more casual and perhaps performative side, such as when he expresses great pleasure upon receiving and eating pickled plums offered by a subordinate.

A central aspect of Akutsu’s role in the story is his secret and deceptive nature. Officially, he is a high-ranking government official dedicated to protecting the public from rogue psychics. However, it is revealed that he has a secret connection to an Akihabara-type person, an individual who should be an enemy of the bureau he leads. Furthermore, a major battle at a derelict bowling alley, which resulted in the deaths of many bureau members, is suggested to be a hoax orchestrated by Akutsu himself. The responsibility for this incident led to his superior being demoted, which in turn paved the way for Akutsu's own promotion. This revelation paints him as a highly ambitious and duplicitous figure who is willing to sacrifice his own people for career advancement.

Akutsu’s primary relationship is with Sasaki, his subordinate. This is a tense and cautious dynamic, as both individuals are fully aware that the other is hiding significant secrets. Sasaki must be careful not to reveal his magical abilities or the existence of Peeps, the reincarnated sage, while Akutsu works to manage the bureau and possibly pursue his own hidden agenda. Akutsu also plays a key role in the development of the character Shizuka. Recognizing her abilities after an incident, he not only offers her a position within the bureau but also unilaterally decides to give her authority comparable to Sasaki’s, assigning Sasaki to be her mentor and integrate her into the team.

While Akutsu’s specific supernatural abilities are not highlighted, his power derives entirely from his political and administrative position. He holds significant power within the bureau, allowing him to direct operations, assign personnel, and manage information. His notable abilities are not magical but strategic and psychological; he is a skilled manipulator, a cunning planner, and a master of deception, as demonstrated by the alleged hoax he engineered to gain a promotion. His actions drive much of the bureaucratic and conspiratorial tension within the modern-world segments of the narrative, forcing Sasaki to navigate a perilous work environment where his boss is a potential enemy.
