For the most part, Saburo is a fairly laid-back individual. Like his friends, he is always willing to help others in need, although he usually waits for Kyouhei to extend the offer before doing anything himself. He also shares Kyouhei's second-hand embarrassment for Walker and Erika's open obsession with anime and manga. Saburo's most noticeable characteristic is his strong attachment to his van, as he is shown to fly into a rage should it be damaged in any way (intentional or otherwise).
