"Masaru Shindo, a main character in the Japanese manga ""Evil or Live,"" is a troubled young man struggling with the complex emotions brought about by the overwhelming pressure of societal expectations and his own families’ unfeeling nature.

Masaru is an introverted and sensitive person, unable to find acceptance or emotional support from either his family or others around him. He is also somewhat of a loner and struggles with feelings of isolation and alienation.

Despite his initially reserved behavior, Masaru possesses great intelligence and a strong sense of justice. These qualities are evident in the way he approaches the evils of the ""correctional education"" system that seeks to brainwash and control its students. He rebels against the system, leading a group of fellow students in a rebellion that aims to tear down its inhumane practices.

Despite his best intentions, however, Masaru's inward turmoil and unstable emotional state often lead him to make poor decisions. He can be prone to explosive outbursts and self-destructive behavior. It is clear that his anger, fear, and loneliness are a significant factor in the battles he faces both with himself and his surroundings.

As the story unfolds, Masaru's character arc focuses on his journey towards self-realization and redemption as he confronts the dark forces that seek to destroy his individuality. Ultimately, Masaru emerges as a compelling and dynamic character, one who embodies the timeless human struggle for freedom and self-discovery."
