Description
Daichi Ishizaki is a male student of the Advanced Nurturing High School, beginning his first year in Class 1-C and subsequently advancing to Class 2-C. He carries the student identification number S01T004656 and was born on April 14, making him 17 years old.

Ishizaki has a background as a problem child, known for fighting and delinquent behavior during his middle school years, where he was reportedly feared by almost everyone. He possesses an appearance that matches this reputation, with dark green hair and dark green eyes, and he wears his school uniform in a modified, disheveled way that includes an unbuttoned vest, contributing to a rough and rebellious impression.

In terms of his official school evaluations, Ishizaki has a very low academic ability, rated at D- (21 out of 100), indicating he does not excel in his studies and is below average. His strengths lie in his physical capabilities, which are rated at C+ (60), making him a capable fighter and enforcer. His thinking and adaptability are rated at C (52), meaning he is not unintelligent but can be naive and is not a high-level strategist, often being susceptible to psychological manipulation. His social contribution score is low at D+ (40), reflecting his aggressive and disruptive attitude, though this shows signs of potential growth. His overall rating is a C- (44), placing him slightly below average overall.

Ishizaki is characterized by his volatile, impulsive, and quick-tempered nature, always appearing ready to pick a fight. He behaves in an arrogant and domineering way toward students from other classes, leading many to avoid him. Beneath this tough exterior, however, he is portrayed as surprisingly straightforward, honest at heart, and possesses a strong sense of duty and loyalty. He is the type of person who understands once a situation is properly explained to him and is willing to put aside past grievances to cooperate with former adversaries, as demonstrated with characters like Teruhiko Yukimura and Kiyotaka Ayanokōji. Despite his tough persona, he also exhibits typical teenage boy reactions, such as becoming flustered around girls like Honami Ichinose or Mio Ibuki.

Ishizaki initially opposed the rule of Kakeru Ryuen within Class C but, after being defeated and overwhelmed by Ryuen's strength, submitted to him and became one of his most loyal and faithful followers. Despite frequently being criticized as useless by Ryuen, Ishizaki deeply admires him and sees him as a legitimate leader. This loyalty is so profound that when Ryuen was defeated by Kiyotaka Ayanokōji and announced his intention to take sole responsibility and withdraw from school, Ishizaki, along with Albert Yamada, was willing to stake his own expulsion to prevent Ryuen from being forced out. His primary motivation is his unwavering allegiance to those he deems strong and worthy of respect, believing that following powerful individuals like Ryuen is the correct path.

In the story, Ishizaki serves as a primary enforcer and subordinate for Ryuen, carrying out his orders without hesitation, even when those orders are morally questionable or cruel. Early in the first year, on Ryuen's orders, he provoked Ken Sudo into a fight and then falsely claimed to be a victim in an attempt to get Sudo expelled. He also participated in the psychological torture of Kei Karuizawa on the rooftop, where he emptied buckets of ice water on her to force her to reveal information about Ayanokōji. During this incident, he and Albert attempted to attack Ayanokōji but were effortlessly subdued.

Following the rooftop incident, Ishizaki's attitude toward Ayanokōji drastically changed, shifting from hostility to a surprisingly friendly and respectful relationship. He began speaking to Ayanokōji cheerfully and casually, as if to a close friend, and developed a genuine trust in him, especially after receiving help to save Ryuen from expulsion during the class vote exam. He later collaborates with Mio Ibuki to seek Ayanokōji's advice and assistance, showing his willingness to work with former enemies for the sake of his leader. During the mixed training camp, he was able to reconcile with Teruhiko Yukimura and learn to work as part of a team, demonstrating his capacity for growth and cooperation.

His key relationships include his absolute loyalty to Kakeru Ryuen, who acts as his class's strategist and leader. He shares a close friendship and bond with his large classmate, Albert Yamada, with whom he often works as a pair. He develops a camaraderie with Mio Ibuki through shared missions for Ryuen. His relationship with Hiyori Shiina is one of respect, as she often tries to restrain his violent tendencies and act as a voice of reason for him, though she finds him difficult to control physically. Finally, his relationship with Kiyotaka Ayanokōji evolves from antagonism to a close, friendly alliance, with Ishizaki even attempting to recruit Ayanokōji into Class C, believing that a combination of Ayanokōji and Ryuen would be unbeatable.
