Family:
Father: Genichirou, a university researcher specialized in physics and astronomy. He's the type of mad scientist similar to Doc Brown of Back to the Future. He almost never leaves his lab. He'd like Touma to join him in his research. He has a beard which I guess shows how far from the norm he is. (Japanese generally disapprove of facial hair.)
Mother: About a decade younger than her ex-husband, she still keeps in touch with the two. She is described either as a very cheerful young person or an air-head. She is an international journalist and is about 32 when the other Troopers met her in Tenkuden. She gave birth to Touma when she was eighteen. She treats both Touma and his father like friends, Touma-kun and Genichirou-kun respectively.
The name Hashiba was used by Toyokimi Hideyoshi, the person who united Japan before Tokugawa. In history, the Hashiba clan was wiped out by Tokugawa.
In his father's side of the family, there has been a legend about a yoroi that the family once had but lost. Touma was researching ancient history and strategy, taking interest in this opposite to what his father researched. He created a computer program to analyze the data but couldn't understand the output. His mother happened to drop by that day and identified as "Ama no hashidate", one of the three famous sites of Japan and where Touma trains later in the TV series. It is there that he receives his yoroi. The story says he went there during the spring vacation of his second year third semester of junior high. That would mean he got it almost right before the battle. It was probably a year earlier.
Touma's dark blue yoroi is Tenku, Firmament, and draws power from generally air. He has a metal collapsable hankyu, Sho Ha Kyu, that can be hooked on his quiver which supplies an endless amount of golden energy arrows. Touma is skilled both in Eastern and Western archery. His special attack is Shin Ku Ha, Vacuum Wave, which creates a huge air wave that obliterates anything its path (well, except Shuten. And Mukara. And Kikoutei. But that's all.)
Touma has lived with his father in a modern high-rise mansion (i.e. apartment) in Osaka since his parents divorced when he was twelve. His mother has the spare key to drop in whenever she wants. Touma's father's lab is in Kyoto. In the original storyline, Touma's paternal grandfather owned a shrine and Shuu was a foreign student who was staying there (that is, Shuu and Touma grew up together).
Touma has an IQ 250, which means during the TV series, he had the intellectual capacity of a 35 year old. (His mom did say he acted like an old person.) Because of his intellect, others would call him a Living Computer or genius. Adults didn't treat him like a kid, so Touma often acts like an adult (he's the youngest of the Troopers). He actually enjoys studying (what's wrong with that?). He also likes reading detective stories.
Once Touma got a zero on the math portion of the academic tests given as practice for the college exams because he forgot to write his name and the teacher was a substitute who didn't know him.
Though he is usually a cool, self-possessed person, matching his computer-like intellect, his emotions can also make him as violent as a tornado. The Troopers are the first real friends he's ever had and he'll do anything to protect them.
In addition to the interests listed above, Touma's hobbies are sleeping and eating. He has low blood pressure which makes it harder for him to get up but he also likes to sleep. Staying up til two in the morning doesn't help either. His idea of waking early is eleven am. Touma actually eats as much as Shuu (or more in one manga) but it doesn't show and he doesn't talk about food like Shuu either. He does have a sweet tooth.
Touma's blood is AB. By the little Japanese blood-personality chart, that means he has a very high pride, a tendency to insult, and often takes revenge.
