In June 2016, the first season of Ajin: Demi-Human concluded, leaving viewers on the edge of their seats. Based on the manga by Gamon Sakurai, the series introduced Kei Nagai, a young man who discovers he is an 'Ajin,' an immortal being hunted by the government. The show was lauded for its intense action, CG animation style, and its exploration of what it means to be human when stripped of mortality.
Fans still discuss Ajin for its gripping narrative and its unique take on the immortal trope. The series' blend of high-octane combat and philosophical questions about identity and societal fear makes its conclusion a memorable point in modern seinen anime.
