well, dunno if he is kinda of detective or not
he never said he is as it, but one thing is true
HE IS GENIUS, even people around him acknowledge it
as the story tell on very first volume, he is just want to enjoy his high school life which (dunno if right or no) he lost when he jump into MIT when he young, he just want to experience it
But even now he is High school, he is already (correct me if i'm wrong) graduate from MIT
he is acknowledge by another researcher there
mostly in math field (so don't be surprised if you got a case which involve math formula, which is fun to read but you never understand)
Well, Kana, I know your feeling 😛
as wuhugm said he is not famous as detective, but at least as researcher he is acknowledge by people around him
well, mostly the case is murder, but it just coincidence when he or Kana are around,
but to make you interested to read it, this manga have comedy on his own
while it's like Conan in term of comedy, the stoic and dense Touma is main point here
give it a try, the charms of this series lay on the math, the comedy duo, and the short-solved case
