Background / History

William reincarnated as Mitsunobu, the youngest son of the Kudo Family, one of Japan's Ten Master Clans. The original Mitsunobu was a modified human who would have been sickly and likely died before thirty; William's reincarnation made him an anomaly that Retsu Kudou attributed to divine blessing. 1 4

Retsu raised Mitsunobu with unusual care, becoming the family figure through whom Mitsunobu learned familial affection. Retsu later confirms that Mitsunobu is intended to inherit the Kudo Family in the near future. 7 47

Mitsunobu enrolled at First High School despite Retsu's initial opposition. His entrance-exam results broke school records for both magic-sequence scale and target-information rewriting intensity, though he deliberately did not take the final test for undisclosed family reasons. 1 2

At school, he proposed replacing the fixed Course 1/Course 2 hierarchy with semester-end promotions and demotions based on performance. He was subsequently appointed Student Council Vice President under pressure from the Ten Master Clans and with the condition that he demonstrate his worth at the Nine Schools Competition. 3 5

Personality

Mitsunobu is consistently composed, courteous, and difficult to fluster. He maintains formal etiquette even with people he finds immature or provocative, and Saegusa Mayumi's charm initially fails to sway him. 1 3 29

He approaches both politics and combat through analysis. He opposes the assumption that Course 1 students are inherently superior, evaluates people by demonstrated ability, and favors measured action until sufficient evidence is available. 16 29

His restraint does not extend to hostile combatants. During the Blanche incident, he acted decisively against terrorists, used deception to infiltrate their base, and left Shiichi alive only for interrogation. 33 34 36

Abilities & Skills

Eye of Truth-Shattering

An extra-system magic Mitsunobu independently developed at age ten. It observes an opponent's Psion reserves and the programming of their activation sequences.

• Can observe magicians whose strength is equal to or below Mitsunobu's own. 10
• Does not instantly identify the exact spell an opponent intends to cast. 10
• Lets him identify concealed magic activation, analyze physical reinforcement, and assess an opponent's combat condition. 10 13 35
• Its perception led Shiba Tatsuya to become wary of Mitsunobu. 10 13

Kudo Family Camouflage Magic

Mitsunobu is one of the Kudo Family's foremost users of its hereditary infiltration magic.

• Optical Camouflage — manipulates light and uses mental interference to create an invisibility-like effect. 33
• Parade of Disguise — copies a target's personal-information body, including appearance and aura. Mitsunobu used it to infiltrate the Blanche-held library and to make Shiichi's Evil Eye affect a false body instead of his real one. 33 36
• Parade of Disguise is bloodline-dependent and exceptionally difficult; within the Kudo Family, only Mitsunobu and Retsu are stated to wield it with ease. 604

Physical Combat

Mitsunobu combines Kudo martial arts with rapid magic activation and close-range tactical pressure.

• Flash Time — a Kudo martial technique that achieves acceleration comparable to triple-acceleration magic through muscular force and a forceful step, without magical reinforcement. 19 20
• Solid Stone — a C-rank Kudo defensive spell that he used to block Shiba Tatsuya's kick during their mock duel. 20
• Uses physical enhancement magic for sustained movement while retaining a degree of defense against surprise attacks. 9
• Defeated Ichijo Masaki in close combat after Masaki attempted to close the distance during the Monolith Code final. 73

Offensive Magic

Mitsunobu possesses a large and varied offensive repertoire, including original high-rank spells.

• Dispersion Bullet — a C-rank spell that can spread into a broad net of Psion beams. He adapted its normally area-denial-oriented diffusion into precise fire for Speed Shooting. 21 54
• Lightning Flash — emission magic that extracts electrons from matter to induce discharge. His interference power lets him blanket all twelve Ice Pillar Break targets at once. 76
• Atomic Ray — an A-rank particle-wave cannon created through acceleration- and divergence-type magic. It has extreme speed and penetration, but is difficult to control precisely. 39
  • Severed Shiichi's limbs and incapacitated him. 36
  • Mitsunobu estimates that only the Jumonji Family's Phalanx can withstand it. 39
• Dragon Star Cluster — a super A-rank concept derived from Atomic Ray and Split Bullet. Mitsunobu tested it at the school pool, destroying the pool in the process. 39
• Blazing Flame Domain / Inferno Domain — high-output fire magic used against Blanche and in his Ice Pillar Break victory over Ichijo Masaki. 37 76 77

CAD Engineering and Magic Design

Mitsunobu is an accomplished magic engineer as well as a combat magician.

• Developed a fully functional earring-sized CAD, though its early version could store only a limited number of sequences. 18
• Can manually input and activate CAD sequences smoothly. 44
• Adjusted Saegusa Mayumi's competition CAD, removing residual sequences and adding movement-type magic for Monolith Code. 55
• Built the complex activation sequence for Jumonji Takeshi's contact-type Cast Jamming armor using a specialized CAD as reference. 69
• Designed a Strategic-Class Magic sequence and its dedicated CAD blueprints, despite Retsu's concern that successful testing would expose him to military conscription. 46

Equipment / Weapons / Items

• Night — Mitsunobu's specialized handgun-type CAD. 17 19
• Earring CAD — worn on his right lobe; used to deploy a Psion-based sound-insulating barrier. 3
• Three general-purpose CADs — carried because his mastered magic cannot fit within the storage capacity of two standard units. 40
• MARDUK — an unfinished Strategic-Class Magic CAD with a spear-like physical structure rather than the usual sniper-rifle configuration. 80

Relationships

• Retsu Kudou — Grandfather, guardian, and mentor. Retsu raised Mitsunobu with affection, supports his future succession, and worries that his Strategic-Class Magic project will turn him into a military weapon. 7 46 47
• Saegusa Mayumi — Senior, romantic partner, and intended marriage partner. She initially looked after Mitsunobu at school; their relationship became openly affectionate during and after the Nine Schools Competition. 1 49 79
• Shiba Tatsuya — Fellow student, rival, and occasional ally. Mitsunobu recognizes Tatsuya's analytical ability and combat experience, duels him to establish his capability, and later coordinates with him during the Blanche crisis. 10 20 34
• Shiba Miyuki — A fellow modified human whose exceptional level of genetic adjustment immediately drew Mitsunobu's interest. 4
• Jumonji Katsuto — Ten Master Clans peer and strategic partner. They cooperate during the Blanche incident and jointly plan First High's Monolith Code campaign. 33 66 69
• Jumonji Takeshi — Monolith Code teammate whose close-combat ability and Decomposition defense let Mitsunobu focus on offense. 66 68 73
• Ichijo Masaki — Competitive rival from Third High School. Mitsunobu defeated him in both Monolith Code and Ice Pillar Break. 73 77
• Kuki Ken — Kudo Family butler and trusted adviser who supports Mitsunobu's investigations and business plans. 25 45
• Kuki Uichi — Employee entrusted with managing FIRE while Mitsunobu remains in school; he became committed to the company after reviewing Mitsunobu's CAD prototypes. 44 45
• Fujibayashi Kyoko — Investigative collaborator who assists Mitsunobu with the Blanche and No Head Dragon cases. 33 67

Story Role / Major Arcs

• First High School entrance — Enrolls as a Course 1 student, meets Saegusa Mayumi, and pushes for a performance-based route between the two school courses. 1 3
• Student Council and Course 2 reform — Becomes Vice President and advocates for recognizing capability over Course 1 status, including backing Shiba Tatsuya's place in school authority. 5 16 17
• Blanche incident — Leads countermeasures against Blanche's school operation, infiltrates the library, then defeats Shiichi and dismantles the Japan branch's resistance. 33 36 37
• FIRE and Strategic-Class Magic project — Establishes FIRE with Kuki Uichi handling daily operations and begins developing a dedicated Strategic-Class Magic CAD. 44 46
• Nine Schools Competition — Wins Speed Shooting with controlled Dispersion Bullet, leads First High's Monolith Code strategy against Third High, and defeats Ichijo Masaki in both Monolith Code and Ice Pillar Break. 54 73 77
• Public relationship with Mayumi — Uses a dance with Mayumi to repel unwanted attention at the post-competition banquet, publicly kissing her hand and intensifying rumors of their relationship. 78 79

Trivia
