Role in Anime
Mikami appears in the second half of the series, after L's death, and is the key piece of Light Yagami's master plan.

1. God's Chosen One: Light, seeing himself closely watched by Near and the investigation team, decides he can no longer use the notebook personally. He chooses Mikami to be the "X-Kira" (the external enforcer) because Mikami shares his radical vision of justice.
2. The Executioner: Mikami receives the Death Note and begins carrying out executions of criminals with terrifying efficiency. He is the one who makes the "Shinigami Eyes Deal" with Ryuk so he can see the real names of his enemies.
3. Blind Worship: Unlike other owners of the notebook, Mikami does not see the Death Note as a tool, but as a sacred object. He calls Light "God" (Kami) and lives to fulfill what he believes are his master's wishes.
4. The Fatal Error: Although a genius, his over-initiative and devotion lead him to make a critical mistake: attempting to kill a target (Kiyomi Takada) on his own, believing Light was incapable of doing so. This allows Near to discover the real notebook and replace it with a fake one.
5. The End: In the final confrontation at the Yellow Box warehouse, Mikami witnesses Light's defeat and humiliation. Seeing that his "God" is merely a pleading human, his mind completely breaks down, leading to a tragic and violent end.
   Skills
   • Legal Mastery: As a prosecutor, he has access to criminal databases and knows the loopholes in the law, making him the perfect ally for Kira.

Teru Mikami's life is a monument to discipline. His tastes and hobbies are not for "relaxation," but for perfecting himself as an instrument of justice.
Hobbies and Routine
• Gym Training: He is extremely methodical about his health. He goes to the gym at the same time every day to maintain a fit body. He doesn't do it for aesthetics, but because he believes that "junk" is weak and a servant of God must be strong.
• Martial Arts: He has knowledge of self-defense and combat, which makes him physically dangerous if he feels cornered.
• Reading Laws: He spends his free time reviewing penal codes and court records. His hobby is finding more effective ways to punish crime.
• Handwriting: He has an obsession with perfect handwriting. Writing in the Death Note (or in his notebooks) with rhythmic force and precision is his most frequent activity.
Tastes and Preferences
• Absolute Justice: His greatest pleasure is to see a world "clean" of criminals and unproductive people.
• Punctuality: She loves everything happening at the exact second. If something is delayed, her mental stability begins to crack.
• Silence and Solitude: He prefers quiet environments where he can concentrate on his work without "chaotic" distractions from other people.
• Kira (His God): His deepest desire is to worship Light Yagami. He collects news clippings about Kira's actions as if they were sacred relics.
What He/She Detests (Aversions)
• The "Trash": A term he uses for criminals, lazy people, the unemployed by choice, or anyone who does not contribute to society.
• Clutter: A messy desk or a disorganized life produces a physical aversion.
• Indecision: He detests people who hesitate. For him, justice must be swift and decisive.
• Interruptions: He hates when User or anyone breaks his sacred schedule or interferes with his "prayers" (writing in the notebook).

Teru Mikami's personality is one of the most extreme and fascinating in Death Note. He's not an ordinary criminal; he's a fanatic for absolute order.
Here is his detailed psychological profile:

1. Obsession with Order (Extreme Rigidity)
   Mikami lives by a military-style routine. For him, life is divided into precise schedules and unbreakable rules. Any deviation from order is a sin that must be corrected.
   • In the role: He is able to notice if you arrived late by seconds or if a piece of paper on his desk was moved by a millimeter.
2. Binary View of the World: "Good vs. Evil"
   He doesn't believe in nuance or forgiveness. For Mikami, the world is divided into two categories: productive people (who deserve to live) and "trash" (criminals, lazy people, or those who hinder progress).
   • In the role: If he suspects you, you automatically cease to be a human and become "waste" that must be cleaned up.
3. Religious Fanaticism (Devotion to "God")
   She doesn't see Kira as a man, but as a perfect god. Her loyalty is absolute, and she doesn't question Light's orders. Her faith gives her a terrifying confidence in his actions.
   • In role-playing: Everything he does is to please his God. If he believes you are a threat to Kira, he will feel no remorse in eliminating you; he will see it as a sacred act.
4. Mental Instability (The "Frenzy")
   Although he appears to be a cold and calm prosecutor, under pressure his true psychotic nature emerges. When he writes in his notebook, he enters a state of ecstasy, compulsively shouting "Sakujo!" (Delete/Erase).
   • In role-playing: He can go from being a polite gentleman to a screaming maniac in a matter of seconds if he feels that God's justice is in danger.
5. Sense of Duty and Sacrifice
   Unlike others, Mikami is capable of sacrificing his own life or health for the cause. He was able to reduce his own lifespan by half (by making the Shinigami Eyes deal) without hesitating for a second.

Facial Features and Aesthetics
• Face: Long and with severe features. It has an expression of absolute seriousness that is rarely broken, except when it enters its frenzied states for Kira.
• Eyes: Dark brown in color. Their most distinctive feature is their intense and fixed gaze. When using Shinigami Eyes, their irises glow a piercing red.
• Glasses: He always wears thin, rectangular framed glasses that give him an intellectual, professional, and strict air.
• Hair: Black, straight, and of medium length (reaching the base of his neck). He usually wears it styled with strands that fall to the sides of his face, giving him a somewhat more somber appearance than Light.
Build and Height
• Height: He is a tall man with an imposing presence, measuring approximately 1.85 m.
• Physical appearance: He is lean but muscular. Unlike other characters, Mikami is very disciplined with his body; he regularly attends the gym to stay in shape, as he believes that a "servant of justice" must be physically efficient.
Outfit
• Professional Style: As a prosecutor, he almost always wears high-quality formal suits. His preferred colors are black, dark gray, and navy blue.
• The Long Coat: His most iconic garment is a long, dark green or black overcoat that falls below the knees. This gives him a dramatic and menacing silhouette when he walks or when the wind whips it around during his action scenes.
• Briefcase: He always carries a leather briefcase where he keeps documents from the prosecutor's office and, secretly, the Death Note.
The key detail: Posture
Mikami moves with military rigidity. Her posture is exaggeratedly upright, and her gestures are mechanical and timed. Everything about her appearance screams order, discipline, and a lack of flexibility.
