Description
Hijacker A, also known as Masked Takenouchi, is a character whose entire identity stems from a case of mistaken identity and a thwarted crime. His real name is never revealed, and he is perpetually seen wearing a white wrestling mask marked with the kanji character for bamboo, which means "take" and is the first character in the name Takenouchi.

Before his arrival at Cromartie High School, he was an amateur criminal attempting to hijack an airplane that was carrying students on a school field trip. The situation took an unexpected turn when he engaged in conversation with a student named Yutaka Takenouchi, discussing personal anxieties such as the hijacker's agoraphobia, or fear of open spaces and crowds. In the ensuing confusion, the hijacking was successful, but the two men essentially swapped places. The real Takenouchi ended up being flown to the Nevada desert in the United States, while the hijacker remained stranded in Japan. To maintain his anonymity and avoid capture, he adopted the identity of the student he had displaced, enrolling at Cromartie High School while hiding his face behind the mask.

Personality-wise, Masked Takenouchi is defined by a notable contrast between his criminal past and his surprisingly mature, measured demeanor. Having attempted a serious crime, he is nonetheless characterized by a certain nervousness and unease in social situations. However, after the hijacking incident, he reforms his ways and decides to abandon a life of crime. He is considerably older than the other students, likely being an adult in his thirties. This age difference manifests as a sense of world-weary wisdom; he frequently offers advice to his younger, more hotheaded peers, speaking from a place of experience. His motivations are simple: to avoid being discovered as a criminal and a fraud, while quietly integrating into the bizarre society of Cromartie High.

His role in the story is almost entirely dependent on the absurdity of his situation. The core joke is that despite wearing a conspicuous mask and bearing no physical resemblance to the real Takenouchi, almost no one at school questions his identity. Fellow students simply remark that Takenouchi seems to have a different "atmosphere" about him. He lives at the real Takenouchi's house, and even the family does not recognize the substitution. This creates a series of comedic scenarios, especially after the real Yutaka Takenouchi eventually returns from America. Rather than the fraud being exposed, the two are simply seen together, with other students nicknaming him "Masked Takenouchi" to differentiate him from the original. Many students were apparently aware of the deception all along but accepted it without issue.

Key relationships include his connection with the real Yutaka Takenouchi, which is less a friendship and more a bizarre, accidental swap of lives. He also forms a unique working relationship with fellow student Shinjiro Hayashida. The two take off their disguises—the hijacker removes his mask and Hayashida removes his fake mohawk—to work part-time jobs under different names, completely failing to recognize one another as classmates. While the series is largely static, his development is the shift from a nervous, aspiring criminal to a settled, if absurd, member of the school community who is respected for his "adultness" by the other delinquents.

In terms of notable abilities, Masked Takenouchi has no superhuman fighting prowess. His primary skill is deception and improvisation, having managed to seamlessly replace another person in his home and school. He also possesses a degree of esoteric knowledge, such as mastering a fictional martial art called "pillow-jutsu," which involves the technique of softening a pillow with a sharp blow from a long stick. Ultimately, his most defining characteristic is not a skill, but the sheer, inexplicable power of the status quo that allows his disguise to go unquestioned in a school filled with delinquents, robots, and gorillas.
