Akuma-kun

When Mr. Sato, a dedicated employee at the world's largest electronics company, receives an unexpected promotion opportunity, he jumps at the chance. His new assignment: serve as a private tutor to his boss's son, Ichiro Matsushita—a quiet, brilliant child who seems wise beyond his years. As Sato begins his new role, he quickly senses something isn't quite right in the Matsushita household. The previous tutor has vanished without explanation, and young Ichiro possesses an unsettling intensity that makes Sato question what he's gotten himself into. The boy's vast knowledge of obscure subjects and his peculiar behavior hint at depths far more complex than a typical child prodigy. What started as a straightforward tutoring job soon becomes a psychological game of cat and mouse, as Sato realizes his young student may be far more dangerous than anyone could have imagined. In this dark tale where ambition meets the supernatural, an ordinary man finds himself caught in a web of secrets that challenges everything he thought he knew about power, knowledge, and the price of success.
