This is tough since anime isn't as much my thing as it used to be--I'm not familiar with the more shonen action genre either (I prefer my Ouran High Schools and my Azumanga Daiohs).
On that note though, a large part of Tarot's thought processes are based of Kyouya Ohtori from Ouran High School Host Club. From his accounting and business acumen to his way of catergorizing folks and information about them for use later, Tarot is actually rather like the Vice President of the Host Club--he also tries to keep a cooler head hen business needs to be done and even does his best to keep CERTAIN people in the company he's involved in on the track to getting the job done.
I'd also like to add in Yuuko Ichihara from xxxHolic who is not only a businesswoman but also far more knowledgeable about the world, its secrets and people then most are--this is the type of thing Tarot prides himself on. Her business model of granting wishes is also very much like Tarot's.
