Shuichi Aizawa is the most strictly principled, law-abiding, and down-to-earth member of the Japanese Task Force. Unlike the eccentric geniuses or obsessed killers around him, Aizawa represents the perspective of a realistic, hard-working family man and traditional police officer.Core TraitsDeeply Principled: He believes strongly in the justice system and standard legal procedures. He frequently objects to L's illegal or unethical tactics, such as holding suspects captive for months.Blunt and Short-Tempered: He has zero tolerance for immaturity.

He experiences deep internal conflict between his duty to stop Kira and his financial and emotional responsibilities to his family.Skeptical and Observant: After the time skip, Aizawa matures into the sharpest, most analytical detective on the team.

Touta Matsuda is the youngest, most impulsive, and emotionally driven member of the Task Force. Unlike his rigid peers, he represents the "everyman" perspective.Core TraitsNaive and Clueless: Frequently blurts out inappropriate comments and gets distracted by pop culture. His goofy antics constantly annoy L and Aizawa.Desperate for Approval: Driven by a deep desire to prove his worth as a detective, often taking reckless risks to get noticed.Kira Sympathizer: Openly questions if Kira is truly evil, appreciating that crime rates dropped, which creates tension with the team.Loyal to a Fault: Fiercely devoted to Soichiro Yagami and trusts Light completely, defending him blindly until the final breakdown.

Teru Mikami is a fanatical prosecutor chosen by Light Yagami to act as the "X-Kira." He views the world in absolute binaries of good and evil.Core TraitsObsessive-Compulsive: Lives by a rigid, second-by-second daily schedule. He fills Death Note pages with microscopic, perfectly organized handwriting.Extreme Sense of Justice: Suffered childhood trauma from bullying, leading to a lifelong obsession with "deleting" societal scum.Deity Worship: Views Kira as literal God. He zealously chants "Sakujo" (Delete/Eliminate) while executing criminals.Independent Initiative: Highly intelligent but fatally independent.

Ryuk is the Shinigami (God of Death) who sets the entire story in motion simply because he was bored. Unlike the human characters, he has no moral stakes or ideological horse in the race.Core TraitsPurely Bored: He dropped his Death Note into the human world for entertainment. He views the battle of wits between Light and L as a spectator sport.Apple Addiction: He is completely addicted to human apples, which act like a drug to him.

He wears a dark, tattered skin-tight outfit covered in rings and feathers, and has retractable blue-grey wings.
