Due to their parents being deceased, Tadashi is Hiro's primary voice of reason and father figure. In the film, Tadashi and Hiro live in San Fransokyo with their aunt Cass. Although his age is not explicitly described in the film, Tadashi acts very mature for his age. Additionally, Henney describes the character as "pure", even comparing Tadashi to an angel. Tadashi is also a "tech-wizard" who attends the San Fransokyo Institute of Technology, where he conceives, builds and programs Baymax. In the film, Tadashi suggests that Hiro should attend the San Fransokyo Institute of Technology as Hiro is also gifted in robotics and engineering, even more so than Tadashi, his intellect allowing him to graduate from high school at 13. Initially, Hiro dismisses the request, as he chooses to pursue monetary gain from his domination in illegal bot fights in San Fransokyo, even in spite of any risks. Tadashi responds to this by redirecting his little brother's intelligence, taking Hiro with him on a quick trip to his college. From it, Hiro sees just how remarkable the institution really is, and is introduced to Tadashi's friends—Honey Lemon, GoGo, Wasabi, and Fred. Tadashi also introduces Hiro to his project Baymax, a personal healthcare robot. Tadashi designs Baymax to have a huggable build. The film's animation team researched at Carnegie Mellon University to help conceive Baymax's design. Directors Don Hall and Chris Williams wanted Baymax to be "appealing but also huggable." Ryan Potter (Hiro's voice actor) states that Hiro sees Baymax as a representation of Tadashi. The experience inspires Hiro to want to attend the school himself, and, with a small amount of help from Tadashi, he begins working on his own endeavor in order to gain admission. Hiro showcases his project, Microbots, controlled by a neurological headband and highly versatile, at a student exhibition held at the school.
