Shiba Tatsuya (司波 達也) is the main protagonist of "The Irregular in Magic High School" light novel and animated series. He enrolled at the National Magic University Affiliated First High School in April 2095 with his younger sister, Miyuki (深雪) and got accepted as one of the students to be placed in the Course 2 curriculum, marking the start of both the light novel's and anime's series of events. In his second year, he transferred into the newly made Magic Engineering Course.

Appearance and PersonalityEdit

Tatsuya is 175cm tall (178cm in Volume 3), well-built and often described as mundane-looking compared to other characters in the series. He is usually expressionless and very rarely does he get surprised or enthusiastic, and whenever he does, however, it's often at the minimum level. In the anime, he has dark hair that reaches his clear blue eyes in several uneven cut bangs- he shares both his hair and eye color with his sister Miyuki.

Tatsuya is normally wearing his green, white, and black school uniform, lacking the eight-petaled flower emblem on his blazer. At home, he generally wears a nondescript black shirt and pants.

Tatsuya is intelligent and analytical. His emotions are merely skewed in a certain direction, with one particular half becoming especially sensitive. Thanks to this, he can easily and quickly categorize people into two distinctive groups: hostile and non-hostile (while normal people would see 3 types: hostile, neutral and friendly. They would have a hard time to know who is a friend and who is an enemy since they aren't sensitive). This certainly comes in handy for his military and political life and anything related to conflicts (which is almost everything in life). 

To hunger, but not gluttonous. To arouse, but not lustful. To tire, but not slothful.

— A Narrated Description for Tatsuya , Volume 3: Chapter 2

He doesn't possess the ability to hate nor could he feel any strong emotions like fury, despair, envy, hatred, disgust, gluttony, lust, sloth, and love. 

The only aspect in him that is perfectly natural — the only emotion that remains — is his love for his sister. Because of this, he tends to either spoil her too much, or be overprotective and completely ruthless when there are threats towards Miyuki's safety. In the eyes of their friends, Tatsuya exhibits blatant favoritism towards his sister, and hence is called a siscon[1].

To Tatsuya, for whom not even his own death could induce ‘true fear’ — more accurately, he had been deprived of such an emotion — the fear of losing Miyuki was all the more amplified for there being no other fears to temper him and shook him strongly, deeply, and utterly.

— A Narrated Description for Tatsuya

Due to being treated like a fake magician, he always underestimates his own magic abilities leading to Miyuki taunting him on various occasions.

Shiba sibling's house

Tatsuya is the eldest son of Shiba Tatsurou and Shiba Miya and is eleven months older than his younger and only sibling Miyuki (his birthday falls on April 24th). They are mostly mistaken as twins for being in the same year.

Prior to the timeline at the beginning of the series, their father remarried six months after their mother's death, and the two of them are living alone in a house, which is described as a place that vastly exceeds the average size.

Their house has two basements: one being Tatsuya's lab with state-of-the-art equipment and the other being an empty one where new types of magics created by Tatsuya are tested.

He was not one of them. Even though the blood of the Ten ran through his veins, he was never considered one of them.

— Tatsuya thinking to himself , Volume 4: Chapter 14

Tatsuya is a child born from the Yotsuba family. Although this is the case, he wasn't accepted as a legitimate member due to the fact that he cannot wield magic. The two types of magic he can freely wield are not considered magic by the family's standards due to its nature of only 'destroying' and 'restoring' information, not 'altering' them.

At the present timeline, besides his two natural magics, he was only able to use imitation and theoretical magic, something which could be owed to his other unique ability and superior intellect.

Despite this deficiency, he has taken advantage of his physical prowess and ESP power to become Miyuki's Guardian, which is considered to be a job of the highest importance in the Yotsuba clan. His combat prowess has also become respected enough that he is now a primary combatant of the Yotsuba clan.

Experiment on a six-year old Tatsuya

Main article: Reminiscence Chapter

With the goal of giving Tatsuya the ability to wield magic like everyone else, his mother, Shiba Miya and her twin sister, also his aunt, Yotsuba Maya, experimented on the six-year-old Tatsuya. Miya used the forbidden Non-Systematic Magic 'Mental Design Interference,' forcibly altering the area in the consciousness that creates strong emotions, called the limbic system, by inputting a Magic Calculation Model, creating an artificial Magician.

This is the alias that Tatsuya is using in the military, to be specific, in the 101 Independent Magic-Equipped Battalion.

Physical AbilitiesEdit

Tatsuya specialises in combat and assassinations. His skills in slipping behind enemy lines are almost top notch. 


Main article: Kokonoe Yakumo

Tatsuya is a student of Kokonoe Yakumo, a famous ninjutsu user and someone who passes on traditional shinobi[2] magic know-how. Due to this, he can handle multiple opponents at once and emerge unscathed. Tatsuya's physical abilities surpass normal magicians, who usually just rely on magic to accelerate or fortify their bodies to prevent injuries. It is also thanks to his training that Tatsuya can sense dangerous/hidden presences without relying on

Tatsuya vs Kokonoe Yakumo

his unique magic, Elemental Sight. Yakumo himself has said, "It’s possible that I’m unable to beat Tatsuya-kun in pure martial arts already..." thus proving his physical prowess. Before his present age Tatsuya had learned enough techniques to be considered a master or something close. Through his ninjutsu training, he is a master of chi utilization. 

Magical AbilitesEdit

Main article: Born-Specialized Magician

Tatsuya is a Born-Specialized Magician (BS Magician) and is always emphasized as someone whose capability in wielding magic doesn't classify him as any more than a Rank C Magician, by international standards. The fact that he cannot alter the Eidos is one of the main reasons why the Yotsuba family treats him as an outcast or a fake magician.

Tatsuya can only freely wield two types of magic, based on his innate ability- "direct interference into structural information." One is unknown to the world while the other magic is considered difficult and high-class. Owing to this circumstance, his magic calculation area is dominated by these two powerful magics, making him unable to wield other magics efficiently.

The magical abilities that he has obtained at birth allows him to excel in combat, and makes him a balanced fighter. Tatsuya's magical abilities and talents gives him the greatest advantage in long-range magic. It has been stated that Tatsuya excels in extreme long-distance precision attacks and OTH (over the horizon) sniping, and can easily snipe human targets from a range roughly distanced at 1200 meters. It is indirectly implied throughout the series, that his OTH (over the horizon) magical sniping gives him the greatest attack range in the magical community.


Using his natural magic, Decomposition, his speed was mentioned to be 0.05 seconds for his magic to work. With no retaliation, he is capable of sniping 36 targets simultaneously, but under constant fire his upper limit for mass targeting is 24. By decomposing matter directly into energy with his Material Burst magic, Tatsuya can generate massive explosions that can eradicate anything within their radius.

artificial magic. However, even making one cannonball of psions is something that normal Magicians would be unable to create even if they spent the entire day on it.

Systematic-Type MagicEdit

See Also: Operation

In order to allow him to use "magic," his mother and her twin sister operated on Tatsuya when he was 6 years old, installing a magic processor into his mind allowing him to use magic. However, it was inferior to a natural processor so the only advantage the processor granted him was that it allowed him to instantly access short magics (5 steps or fewer) instantly without any buffer or calculation. Since most combat magics use 5 steps or fewer, they are available to him. Also, because the processor can show him the exact magic that needs to be used, he can only use a very long round-about method to execute complex magics (hence why he failed the speed portion of the practical). He is also very adept at manipulating Oscilliation Magic.

Other spells he often uses: Resonance, Phantom Blow, and Compound Waves.

Miyuki, as a natural Mental Interference Magician, acts as his limiter. This stops him from showing his true might, making him unable to use his Strategic spell and blocking his access to his psion reserves. When the limiters are released, he is surrounded by a maelstrom of psions that would cause anyone to lurch away from him; an amount greater than his sister's and Mayumi's. (This is hinted by Lina to be twice her own count, which is similar to Miyuki's.) The full effects of this limiter are currently unspecified and thus it's unknown if it affects his ordinary magic talent or limits his ability to use his natural magics.

Selective Cast JammingEdit
It is utilizing the Psion waves that interferes with one another when using two CADs simultaneously. One CAD is doing the jamming spell, and the other CAD doing a spell reversal. From two opposing spells, the simultaneous activations will release Psion incident interference waves as Non-Systematic Magic.

Active Air MineEdit

Related Article: Kitayama Shizuku — Active Air Mine

It is a technique specially made for the Speed Shooting event that Shizuku participated in.
This magic sets numerous epicenters within the area where the targets are present, which generate virtual waves that give rise to vibratory waves within the targets. Instead of directly applying the waves to the targets with magic, the user sets up an area which causes the phenomena of applying such waves to the targets. The moment the waves from the epicenter come into contact with such a target, the virtual waves become real waves within the target and affect it in reality.
The effective scoring area in Speed Shooting is a cube of 15 meter proportions set in the air. Shiba-kun's Activation Sequence sets another cube within this which is 10 meters on each side, with the vertices and the center, nine points in total, being designated as epicenters.

Suzune , Volume 4: Chapter 8

There is no need to enter variable coordinates separately each time, but instead, the user can simply input into the Activation Sequence the number they desire and instantly invoke the magic. This magic doesn't require changes in duration or power either.

Silver Horn Model "Trident"Edit

A Specialized CAD based off the long-barreled Silver Series Silver Horn. It is inputted with most of Tatsuya's high level Decomposition magics. Tatsuya has used this CAD to cast high precision magic, decomposing needle-sized holes targeting his opponents' nerves and blood vessels to incapacitate and cause severe pain. It is customized specifically to activate three consecutive magics into one Magic Sequence. In the Battalion, "Trident" is the name given to this merciless triple Decomposition magic as well as the CAD that performs this. This is Tatsuya's favored instrument. This CAD has interchangeable cartridges loaded with different types of magic.

Third EyeEdit

A large caliber rifle CAD designed specifically for Tatsuya to use Strategic Level Decomposition Magic "Material Burst." It has acceleration and movement compound sequences inbuilt and is connected to a satellite to allow for precision targeting. With this CAD, Tatsuya was able to hit a 50mg drop of water from 80 km away. Due to its nature as the only weapon Material Burst can be used reliably and quickly with at long distance, the key card to the CAD case is kept by Major Kazama and the CAD is maintained by the engineer Captain Sanada. It is kept at the Independent Magic Equipped Battalion's headquarters.

He owns an electric motorcycle and a bulletproof car.

  • Shiba Tatsuya's personality, equipment, names, and abilities are heavily based on the god Shiva (Mahesvara). Shiva is one of the most revered and fascinating figures in Hindu mythology; he is the god who represents everything outside the established system, described as being both God and the Devil in one, and is heavily worshiped and feared. Shiva is held to be the Supreme God within Shaivism, one of the four largest sects within Hinduism.
  • Shiba Tatsuya's nickname [The Destroyer] (or God of Destruction) was given to him by Raymond Clark, one of the Seven Sages.
  • Shiba Tatsuya has admittedly called several female characters beautiful in different degrees in his thoughts, though he has never shown any trace of arousal or attraction, as well as embarrassment, regardless of the situations or how any female character present themselves to him.
  • Tatsuya's voice actor is Yuuichi Nakamura, the same person who had voiced Kyousuke Kousaka, the male protagonist of Ore no Imōto ga Konna ni Kawaii Wake ga Nai. Many fans have found this humorous due to the fact that Shiba Miyuki's voice actress is Saori Hayami, the same person who had voiced Ayase Aragaki of the same show. Ironically, Ayase would often criticize Kyousuke due to his sis-con personality.
  • Tatsuya and Miyuki appear in a commercial board at a building in Accel World Episode 6.
  • It was mentioned in the Summer Beach arc that Tatsuya's body was covered with scars all over except for his head.
  • It may be a coincidence that Tatsuya Shiba's initials are the same as Taurus Silver's.
