Tatsuya Shiba

Demon of Okinawa, God of Destruction, Mahesvara, 司波達也

Shiba Tatsuya is a first-year student in Course 2 of First High School. He's the eldest son of Four Leaves Technology (FLT) company's president, part of the Yotsuba clan. His only sibling is Shiba Miyuki. Since they were born in April and Miyuki in March, they are studying in the same year according to the Japanese school system. While Tatsuya scores near the bottom in technical skills, Miyuki ranks at the top of her class as freshmen. The school divides students into high scorers (blooms) and low scorers (weeds). Despite his cold demeanor, except for his sister and friends, Tatsuya shows a warm personality.

It is later revealed that Tatsuya is "'half' of Taurus Silver," while the "Taurus" part came from Ushiyama, who Tatsuya calls Mr. Taurus. It is also stated that this is done because Tatsuya is "still an underage student", so he couldn't patent his own theories. 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.Tatsuya was granted the ability to wield magic, but still not par to what they expected. Unfortunately, the artificial magic operation area is markedly inferior in performance to that of a natural one, and he could only end up being used as a Guardian. He developed a new countermagic against Jumonjis phalanx. This magic is called Baryon Lance. He used it in Vol 23 to secure his victory against Jumonji.

It is also stated that this is done because Tatsuya is "still an underage student", so he couldnt patent his own theories. He was born without any magical ability apart from decomposition and regrowth, which was unacceptable to the Yotsuba clan. In hopes that his magical abilities would improve, his mother, Shiba Miya and her twin sister, his aunt, Yotsuba Maya, experimented on the six-year old Tatsuya. He developed a new countermagic against Jumonji's phalanx. This magic is called Baryon Lance. He used it in Vol 23 to secure his victory against Jumonji. He is also part of the JSDF 101 Independent Magic-Equipped Battalion, a highly elite magical fighting force, despite being in high school. He wields several personal magics, gram dispersion, mist dispersion, regrowth, and material burst, rating him to be a strategic magician. He uses this power three times so far, once in anger when the Great Asian Alliance invaded Okinawa in 2092, and twice during Scorched Halloween three years later.
