     Tatsuya & Miyuki Shiba 

Tatsuya Shiba

Voiced by: Yuuichi Nakamura
Course: 2 (Volume 1~11), Magical Engineer Course (Volume 12~)
Year: 1st (Volume 1~11), 2nd (Volume 12~)
Class: E
The male protagonist and the elder brother of Miyuki. He is a Guardian/servant of the Yotsuba clan, one of the 10 Families. He is also the Special Lieutenant of the 101st Independent Magic-Equipped Battalion.

  • Action Hero
  • Affectionate Gesture to the Head: His default method to soothe Miyuki.
  • A Lady on Each Arm: Courtesy of Miyuki and Honoka.
  • Almighty Janitor: He constantly outperforms Course 1 students despite being a Course 2 student, due to poor results in practical testing. However, it turns out that the criteria used for testing practical magic ability is faulty for irregulars like Tatsuya.
  • Almost Kiss: Twice. Miyuki nearly kissed him while he was sleeping and they needed to be very close in volume 11 for Miyuki to kill a Parasite.
  • Aloof Big Brother: Was this to Miyuki until she decided to get closer to him.
  • Always Someone Better: A lot of people got massive inferiority complexes after seeing his skills.
  • Accidental Pervert: When he saved Honoka from drowning.
  • Anti-Hero: The Pragmatic variation.
  • Anti-Magic: He is able to use the two strongest Counter Magics Gram Demolition and Gram Dispersion.
    • He also found a way to use Cast Jamming without Antinite.
  • Animal Motifs: Dragon. His Code Name, Oogura Ryuuya means Great Black Dragon.
  • Asexuality: He has almost no sexual lust. He can still feel physical arousal, but avoids actions and thoughts that would cause it.
  • The Apprentice: Yakumo's.
  • Awesomeness by Analysis/Super Senses: Elemental Sight.
  • Badass:
    Mayumi:... Tatsuya-kun, are you planning to fight them?
    Tatsuya: That's an incorrect way to put it. I'm not going to fight them, I am going to annihilate them.
  • Being Watched: Sometimes he doesn't even need to use Elemental Sight to know it.
  • Berserk Button: Don't touch his sister.
  • Beyond the Impossible:
    • Flight magic was considered impossible using Modern Magic (it could be done with Ancient Magic) before until he discovered a way for Modern Magicians to do it.
    • Elemental Sight allows him able to read activation sequences, which is impossible for other magicians meaning that they can't use Gram Dispersion or his version of Cast Jamming.
  • Big Brother Instinct: Endangering Miyuki is the only way to genuinely anger Tatsuya. The one time Miyuki's life was actually in danger he went on a rampage so devastating it earned him the nickname Mahesvara from the Chinese. He killed their guys so hard an entire nation dare not even speak his name.
  • Big Brother Is Watching: Literally. Can keep an eye on Miyuki at anytime with Elemental Sight. Not that she minds.
  • Big Damn Heroes: To save Erika and Mikihiko from the parasite.
    • Also to save Mizuki from being possessed.
  • Blood-Splattered Warrior: After killing a terrorist at Yokohama.
  • Bodyguarding a Badass: As Miyuki's guardian.
  • Born Winner: Even though not everybody can use magic and some lineages are more powerful than others, Tatsuya qualifies. The Yotsuba is the most powerful clan among the 10 Master Clans in Japan. There are two magician lineages in the Yotsuba clan. Some of them are born with a strengthened mind manipulation magic (Miyuki and Miya) and the others are born with a very strong ability. Tatsuya and Maya belong to the latter category.
  • Bridal Carry: Done to Miyuki from times to times. Who totally loves it.
  • Broken Ace: His practical school results aside, he is a Teen Genius and is good at every sports, he is so good that point his friends joke that he is omnipotent. But most of his friends aren’t aware of his troubled past and how Tatsuya views himself because of this operation.
  • Brother-Sister Team: When working with Miyuki.
  • Bullet Catch: Played with in Volume 7, he used his Decomposition on the physical body of the bullets, giving the impression that he was catching them.
  • Celibate Hero: Justified. He can't feel emotions like love.
  • Chessmaster Sidekick: During the Nine School Competitions, as an engineer.
  • Chick Magnet: A lot of girls fell for him, even his own sister. He became more popular with girls after demonstrating his prowess during the Nine Schools Competition.
    • Clueless Chick Magnet: His lack of a normal range of emotions means that he often misses the hints that a good number of the girls/women around him are romantically interested in him. When clearly faced with a declaration of love, he demonstrates himself to also be a Celibate Hero.
  • Child Soldier: Joined the army at 13.
  • Combat Pragmatist: His tactics.
  • Code Name: Oguro Ryuuya.
  • Cool Gun: His CADs, Silver Horn, Third Eye, and Trident, are shaped like one.
  • Covered with Scars: Has many scars all over his body though it's hidden by his clothing.
  • Curbstomp Battle: He won against Hattori in less than 5 seconds. He had made his preparations beforehand though.
  • Deadpan Snarker
  • Death Glare: He gives one to a committee organizer who he catches trying to upload a virus into Miyuki's CAD in episode 17. He's only stopped because Retsu Kudou personally came to the inspection area to see what was the ruckus was, the latter also being displeased that there was someone like that working for him.
  • Declaration of Protection: To Miyuki. Many times.
  • Disintegrator Ray: Can perform this with his Decomposition magic.
  • The Dreaded: Those who know his true powers, most notably the Chinese, are very scared of him.
  • Earn Your Title: Got named Mahesvara after the battle of Okinawa where he restored soldiers who were fatally injured and decomposed completely his enemies
  • Emotion Suppression: He can't feel fully his emotions due to the process that made him an Artificial Magician, leaving him somewhat disconnected from the others his age.
  • Energy Ball: Gram Demolition is a cannonball of Psion.
  • Experienced Protagonist: He is still training and becoming stronger but he was already one of the strongest magicians at the start of the story.
  • Fantastic Nuke: Material Burst.
  • Fighter, Mage, Thief: In Monolith Code, as the thief.
  • The Gadfly: When he's feeling playful.
  • Gadgeteer Genius: He invents a lot of interesting CAD's that prove to be useful for his friends, such as the flying spell Miyuki uses during the Nine Schools competition.
  • Good Thing You Can Heal: His Self-Restoration will automatically restore his body when he is significantly injured or when an abnormality occurs which reduces his combat ability. He can restrain it through conscious control to punish himself or prevent others from noticing his ability.
  • Goal in Life: His dream is to develop Gravity Control-Type Thermonuclear Fusion Reactor so that Magicians won't be treated as mere weapons.
  • Guile Hero
  • The Gunslinger/Mage Marksman: Very good with guns and gun-shaped CADs.
    • Guns Akimbo: He is one of the few magicians who can use two CADs at the same time. He actually has three CA Ds—twin pistols and a bracelet-type—during the Newcomers Monolith Code competition.
    • Gun Fu: In episode 16 to destroy Masaki's Air Bullets.
  • Healing Factor: To the point of being able to survive a shot through the heart like it was nothing.
  • Healing Shiv: He can apply his Healing Factor (Regrowth) to anyone by shooting you with his gun.
  • Homage: To Batman in volume 12.
  • Humble Hero: Despite his strength and his talents he thinks he is nothing special.
  • Hyper Competent Sidekick: Hence the reason why most of his Senpais abuse of him.
  • I'm Having Soul Pains: Can inflict this with Far Strike.
  • Improbable Aiming Skills/Spread Shot: Can snipe 36 targets simultaneously.
  • Ignore The Fanservice/Not Distracted by the Sexy: See above as to why.
  • Incest Subtext: Tatsuya plays it for laughs.
  • Invincible Hero: He always loses against Yakumo but has yet to lose against other opponents. He wishes to remain unbeatable so that Miyuki will be proud of him.
  • Lovable Rogue
  • Mistaken for Romance: When they go out together people tend to assume he and Miyuki are a couple.
  • Mr. Exposition
  • Mr. Fixit
  • Names to Run Away From Really Fast: Mahesvara, the destroyer and restorer of worlds.
  • Nerves of Steel
  • Oblivious to Love: He never notices when a girl likes him. This is due to Tatsuya's lack of strong emotions.
  • One-Man Army:
  • One-Hit Kill: When using Mist Dispersion to decompose the whole body.
  • Person of Mass Destruction: As a Strategic Class magician. His strongest magic "Material Burst" is capable of converting matter to energy according to Einstein's E=MC 2 equation.
  • Promoted to Playable: A non video game example. After the schools Monolith Code Team gets badly injured, he's forced to participate.
  • Razor-Sharp Hand: Can coat his hand with Decomposition magic to tear the flesh of his enemies.
  • The Rival: Seen as one by Masaki and Shinkurou.
  • Role Reprisal: Was played by Yuuichi Nakamura in the Audio drama CD.
  • Savvy Guy, Energetic Girl: With both Erika and Mayumi.
  • Science Hero:
  • Second Year Protagonist: Starting from volume 12.
  • Secret Identity: He is the software developer half of the legendary CAD technician known to the public as Taurus Silver; his mom is the sister of the current head of the Yotsuba clan.
  • The Stoic: Largely due to not being able to show emotions any longer due to various things done to him. However, threatening Miyuki will still set off his Berserk Button and he will show you a Death Glare so terrible you'll regret incurring his wrath.
  • The Strategist
  • Superpower Lottery: Decomposition magic and Regrowth are very powerful, he also masters the two most powerful Counter Magics. There is Elemental Sight too.
  • Super Soldier: He's an artificial magician and consider a top-secret asset of the military—equaling a strategic weapon like an ICBM.
  • Teen Genius
  • Terror Hero: Due to the mystery surrounding his magics, people tend to be afraid when he uses them and he is fully aware of it.
  • Touch of Death: His Decomposition magic at full-contact.
  • Training from Hell
  • Tranquil Fury: Partly due to not being able to really display emotions any longer.
  • Troubling Unchildlike Behaviour: He was a Child Soldier after all.
  • Tykebomb: Trained since his childhood to be Miyuki's guardian, his mother even removed all his emotions save for his love for his sister so he'll do his best to protect her at any cost.
  • Urban Legend: Many persons think Mahesvara doesn't exist.
  • Vitriolic Best Buds: With Mayumi. Most of their interactions are verbal sparring.
  • Weak, but Skilled: He is this when he is not using his innate magics.
  • What Is This Thing You Call Love?: Sometimes wonders what is love since he can't feel it.
  • Willfully Weak: Since he must hide most of his abilities, he can't fight at full power. Granted, a few of his abilities are also not readily available to him. An example would be his Decomposition magic "Material Burst" which requires the "Third Eye" CAD in possession of the military as well as Miyuki removing her suppression effect on his power.
    • The thing about "Material Burst" is that he can use it(Reminiscence Chapter), but he was also in range of the enemy's attack(Ships that could launch rockets at 20km). The "Third Eye" CAD just allows him to fire "Material Burst" at a safer distance.
  • Wise Beyond Their Years: Many persons think Tatsuya is too mature for a teenager.
